The human brain is a multifunctional and multilevel system that can produce resonant dynamic reactions. In the presence of external influence, the brain is able to change activity and rhythms of activity. Since the beginning of the 20th century, electrical activity has been studied by scientists around the world.

The human brain is forced to generate electrical impulses in order to maintain its normal functioning throughout a person’s life.

The creation of impulses is the area of ​​responsibility of nerve cells, the total number of which amounts to tens of billions.

Alpha activity was discovered by the German scientist G. Berger, who was able to identify an unusual type of vibration generated by the human brain. The frequency of these oscillations ranged from 8 to 13 Hz. Later G. Berger also discovered other rhythms.

Alpha rhythm value

Alpha rhythms were recorded using EEG, which were suppressed by beta rhythms. Beta waves only appeared if the patient opened his eyes during the diagnostic process. With the help of EEG, doctors today can also detect disorganization of the alpha rhythm, which is already a pathological condition.

The human brain operates on a relatively small amount of electricity, but this allows it to be the main control center and regulate the functioning of the central nervous system and internal organs. Therefore, he needs regular stimulation of electrical activity, which is important for both children and adults.

Alpha brain activity, which occurs when a person is in a relaxed state, is most interesting to scientists. For example, it is recorded in a state of drowsiness, when the observed person is not yet asleep, but has not woken up, and it cannot be said that the person is alert and has completely recovered from sleep.

When the brain works in alpha mode, a person has the opportunity to receive a huge amount of information. It is customary to distinguish between slow and fast variants of alpha rhythms.

Positive Impact

When the human brain functions in the alpha activity mode, its state is characterized as calm, the most optimal, so its importance is difficult to overestimate. The human central nervous system has two important mechanisms in its work: self-regulation and self-healing. Due to these functions, brain activity increases and the mental resistance to irritants is supported.

When normal, the alpha rhythm of the brain causes many positive effects:

• There is an improvement in blood supply to the brain structures, therefore the saturation of the organ with useful microelements and oxygen is accelerated.
• There is an increase in the rate of recovery of the human body as a whole, which is important, for example, after suffering serious illnesses.
• Increased energy circulation occurs.
• There is an increase in intuitive mental activity, which allows you to spend less energy on solving assigned problems.
• The brain, working in alpha activity mode, can reprogram consciousness, resolve many psycho-emotional problems and remove the following interference: tension, anxiety, stress, insomnia, etc.
• The manifestations of negative conditions are reduced: childhood traumas, life difficulties.

Ways to stimulate alpha waves

On the EEG, alpha rhythms can be observed only in cases when the human body is completely relaxed. Those observed in this state are distracted from problems, so stress is relieved. A slowdown in mental activity has also been noticed, so the consciousness is “cleared”. This allows you to create new ideas, increases the creativity of mental activity, and gets rid of the creative crisis.

If a person experiences severe and prolonged brain activity for some time, then the normal activity of the organ stops. The solution to this problem is to increase alpha waves and relieve mental stress.

There are many techniques that can stimulate alpha waves:

• Sound waves. A simple and accessible technique in all respects, with the help of which alpha activity increases, and the process itself brings a “dose of pleasure” to a person. The technique consists of listening to special music, which consists of stereo sounds.
• Yoga. Long-term yoga exercises, provided the exercises are performed correctly, act as a powerful activator of alpha activity in the brain, which can moderately and not dramatically increase the required levels.
• Meditation. With the help of meditation, you can teach your body to relax automatically, but this will require spending a lot of time going through a huge number of practical sessions.
• Breathing exercises. The method implies that the person will have to constantly maintain deep breathing. This process saturates the brain cells and internal organs with oxygen. If you do breathing exercises systematically so that it becomes a habit, the creation of alpha waves will occur automatically.
• Hot baths. Relaxation almost always occurs after taking a hot bath, which also eliminates fatigue. The production of alpha waves is the main reason for the relaxation of muscle structures.
• Alcoholic drinks. Not a recommended method, which, oddly enough, also allows you to activate production and get an increased level of alpha waves. Alcohol is used by many people to relieve stress. Immediately after drinking alcohol, alpha waves begin to form, which allows a person to enter a state of relaxation, detachment from the world and relaxation.

Pathological indicators

To clarify the current values ​​of rhythms, electroencephalography is used as the main diagnostic technique. On EEG, the normal alpha wave index is in the range of 80-90%. If such indicators are absent or are below 50 percent, then this characteristic will indicate the presence of pathology.

It has long been proven that in pre-retirement and retirement age the amplitude of alpha activity begins to decrease significantly, which is due to the deterioration of blood supply to the brain and organs as the body ages.

Normal amplitude values ​​during EEG testing range from 25 to 95 μV. Research conducted in the middle of the 20th century made it possible to derive such a concept as “brain dysrhythmia.” But further research has shown that not in all cases dysrhythmia will indicate the presence of pathology in the observed person. The EEG can also show special types of BEA (bioelectric activity), epileptiformity and diffuse changes.

Abnormal and insufficient alpha activity values ​​are usually detected in certain diseases:

• Epilepsy (various forms of this disease, including those associated with drug use). With this pathology, the patient develops direct or interhemispheric asymmetry in the cerebral hemispheres of the head. Both frequency and amplitude suffer. This may indicate disturbances in interhemispheric integration.
• Oligophrenia. There is an abnormal increase in total alpha wave activity.
• Problems with blood circulation. Pathology of alpha activity almost always develops with circulatory disorders, narrowing or dilation of cerebral vessels. If the severity of the disease is high, then there is a significant decrease in average activity and frequency indicators. Problems are also observed with beta-lactamase activity of bacterial agents.
• Hypertension. This pathology can weaken the rhythm frequency, which is not enough for normal relaxation of the body.
• Inflammatory processes, cysts, tumors on the corpus callosum. Diseases of this type are considered extremely severe, therefore, when they develop, the asymmetry between the left and right hemispheres can be very serious (up to 30%).

To assess the activity of alpha rhythms, EEG is regularly performed in many pathological conditions: dementia (acquired or congenital), VSD, traumatic brain injury. The data obtained will allow us to choose the right treatment for diseases that will correspond to the existing rhythms.

When deciphering the EEG, in some cases the presence of disorganized alpha activity may be noted. Disorganization or complete absence of alpha activity may indicate acquired dementia. Alpha rhythms are also disorganized when psychomotor development is delayed in children.

Additional indicators

The functioning of the human brain and the electrical activity it generates are inextricably linked states. Activity is caused by the production of impulses by nerve cells. In comparative terms, the electrical activity of our brain can be considered insignificant, because its indicators are at a level of several millionths of a volt.

Three main groups of rhythmic indicators of the human brain can be distinguished:

1. Beta activity. Beta rhythms begin to form in a person at the age when he begins to think logically for the first time and try to control something. The complete formation of this rhythm is observed, provided the child develops normally, by the age of five. The production of beta rhythms occurs naturally, without external stimulation, when the child is awake. The manifestation of this type of brain activity is observed during mental activity, when reading, during processing of received information. Without beta activity, communication between people and any activity is impossible.
2. Delta activity. The formation of this rhythm occurs at the moment when the fetus is in the womb. It is usually recorded during the examination of a pregnant woman during the second trimester. Normal indicators of delta activity on the EEG are frequency from 0.1 to 5 Hz, amplitude - from 30 to 40 μV. Delta waves are formed during natural sleep, during comatose states or during a drug-induced coma (in this state, asynchronous delta waves can be recorded).
3. Theta activity. The formation of theta rhythms occurs at approximately 2-3 months of fetal development in the womb (they are usually recorded only at the end of the third month of pregnancy). Theta activity predominates in children under three years of age. After 18 years, theta rhythms in the human brain are formed in a state of peaceful and moderate wakefulness, gradually turning into sleep.

Disadvantages of Alpha Wave Stimulation

In conclusion, it must be said that an excessive amount of alpha waves can cause the development of various negative conditions in the human body. Therefore, it is not recommended to stimulate alpha waves if all indicators are already within normal limits.

As you know, the human brain operates with electrical signals. It constantly generates electrical impulses called brain waves (or brain rhythms, brain waves, waves of brain activity). The frequency of these pulses is measured in hertz or cycles per second. Well, the dominant frequency of brain waves determines the general state of the brain.

Why dominant? The thing is that the brain does not work as a whole at one frequency. This means that one area of ​​the brain may produce more beta waves while other areas of the brain emit impulses at a different frequency. In general, he may be in a state of calm relaxation, for example, but part of the subcortex will be “itching” about stress and problems at a background level.

They write that the rhythms of electromagnetic oscillations of our brain are directly related to electromagnetic oscillations between the Earth’s surface and the ionosphere, coinciding with them in the main resonant frequencies. Probably, here is the key to the existence of large and small rhythms of the world’s existence, some of which are represented in a person in different ways, and some, resonant with them, in the surrounding space. Like a guitar string makes a sound in unison with a tuning fork, like a bridge begins to vibrate in resonance with the wind, and so on. () Likewise, we can tune in to different cycles and frequencies in the world, entering into resonance with them using simple techniques. One of them is as old as human societies. This is music. Especially rhythmic.

Alpha rhythm (α rhythm, alpha rhythm)- EEG rhythm (electroencephalogram) in the frequency band from 8 to 13 Hz, average amplitude 30–70 μV, however, high- and low-amplitude α-waves can be observed. It is registered in 85–95% of healthy adults. It is best expressed in the occipital regions. The α rhythm has the greatest amplitude in a state of quiet wakefulness, especially with eyes closed in a darkened room. It is blocked or weakened by increased attention (especially visual) or mental activity.

The alpha rhythm characterizes the process of a person’s internal “scanning” of mental images when focusing on some mental problem.

When we close our eyes, alpha rhythms intensify, and this property is successfully used during meditation-relaxation or a hypnosis session. For most people, alpha waves disappear when they open their eyes and a real picture appears before them. Statistical and experimental data indicate that the nature of the alpha rhythm is innate and hereditary.

Most people with a clearly defined alpha rhythm have a predominant ability for abstract thinking. A small group of people exhibit a complete absence of alpha rhythms, even with their eyes closed. These people think freely in visual images, but have difficulty solving problems of an abstract nature.

People who have learned to analyze information when their brain works in the alpha rhythm have access to much larger volumes of information, creative ideas and inspired thoughts are more likely to come to them, intuition is sharpened, which allows them to find new unexpected solutions to problems. No wonder they say: “Close your eyes, and the solution will come by itself.”

When the brain works in the alpha rhythm, a person’s potential for managing his life increases. An understanding comes of how to better deal with various life problems, such as excess weight, insomnia, anxiety, tension, migraines, bad habits and much more. There is an opportunity to learn how to adjust your psyche in such a way as to achieve your goals and turn your dreams into reality.

The work of the brain in the alpha rhythm allows you to quietly enter a state of shallow meditation, as during auto-training and relaxation exercises. Scientists have found that when a person engages in such practices, at the physiological level there is a decrease in the rhythm of brain functioning to the level of alpha rhythm. Taking a warm bath or shower is directly related to the dominance of the alpha rhythm.

Why is the alpha rhythm so remarkable and why does the human body need it? Everything depends on the human consciousness. In a state of complete relaxation and immersion, alpha waves intensify, and healing and cleansing processes begin to take place in our psyche, hidden resources awaken: intuition comes to life, concentration becomes perfectly honed, and extrasensory abilities appear. The world around begins to play with completely different colors, making a person joyful.

Beta rhythm (β rhythm)- low-amplitude oscillations of the total brain potential with a frequency of 15 to 35 oscillations per second, amplitude - 5–30 μV. This rhythm is inherent in the state of active wakefulness. Refers to fast waves. This rhythm is most strongly expressed in the frontal areas, but with various types of intense activity it sharply intensifies and spreads to other areas of the brain. Thus, the severity of the beta rhythm increases when a new unexpected stimulus is presented, in a situation of attention, during mental stress, and emotional arousal. Their amplitude is 4–5 times less than the amplitude of alpha waves.

In a state of beta rhythm, our brain is immersed in the routine of life with a huge number of different problems, in an endless cycle of stressful situations, solving various problems and active concentration, a moving focus of attention. Attention is directed outward.

The beta rhythm is by no means our enemy. It was thanks to the beta rhythm that humanity reached immeasurable heights in technological progress: it built cities, went into space, created television, computers; The development of medicine is also directly related to these waves. This is the rhythm of active creation and life.

Gamma rhythm (γ rhythm)- fluctuations in EEG potentials in the range from 30 to 120–170 to fluctuations per second. The amplitude of the gamma rhythm is very low - below 10 μV and is inversely proportional to frequency. If the amplitude is higher than 15 μV, then the EEG is considered pathological. The gamma rhythm is observed when solving problems that require maximum concentrated attention. The gamma rhythm reflects oscillations that are simultaneously triggered in neurons by an incoming signal from the activating system of the reticular formation, causing a shift in the membrane potential.

The gamma rhythm is observed when solving problems that require maximum concentrated attention. This is the rhythm of composure and concentration on a problem or task, the rhythm of an active collected solution and work. There are theories connecting this rhythm with the work of consciousness. A number of publications report various disorders of gamma activity in patients with schizophrenia.

Gamma rhythm is also a state of communication between a person and “something” that is beyond the understanding of our consciousness. The brain vibration frequency of 50 Hz is what some researchers of Buddhist meditators call enlightenment. Although this is doubtful. This is simply the frequency of maximum concentration, presence here and now. That is, the gamma rhythm allows us to become someone greater and perceive the world from the point of view of this greater one. It's like a superstructure on human consciousness that we can use.

Delta rhythm- from 0.5 to 4 oscillations per second, amplitude - 50–500 µV. This rhythm occurs both during deep natural sleep and during narcotic sleep, as well as during coma. The delta rhythm is also observed when recording electrical signals from areas of the cortex bordering the area of ​​a traumatic lesion or tumor. Low-amplitude (20–30 μV) fluctuations in this range can be recorded at rest during some forms of stress and prolonged mental work.

Characteristic of the stage of deep sleep without dreams. And also, for a state of very deep meditation-dhyana (not relaxation, like the alpha rhythm).

Theta rhythm (θ rhythm)- EEG rhythm Frequency 4–8 Hz, high electrical potential 100–150 microvolts, high wave amplitude from 10 to 30 μV. The theta rhythm is most pronounced in children from two to five years old. This frequency range promotes deep relaxation of the brain, good memory, deeper and faster assimilation of information, awakening individual creativity and talents.

For the most part, in children under 5 years of age, the brain functions in this wavelength range during the daytime, which allows children to phenomenally remember a huge amount of various information, which is unusual for teenagers and adults. In the natural state, this rhythm dominates in the majority of adults only during the REM sleep phase, half-asleep. Characteristic for deep meditation-dhyana. It is in this frequency range that the brain has enough energy to absorb large amounts of information and quickly transfer it to long-term memory, learning abilities are enhanced and stress is relieved. In this range, the brain is in a state of heightened sensitivity. This state is ideal for superlearning; the brain is able to maintain concentration and extroversion for a long time and is not susceptible to anxiety and neurotic manifestations.

This is the range of the upper connections of the brain, connecting both hemispheres and directly the layers of the cerebral cortex with its frontal zones.

Sigma rhythm- spontaneous sigma rhythm has a frequency of 10 to 16 Hz, but generally ranges from 12 to 14 vibrations per second. The Sigma rhythm is a spindle-shaped activity. This is explosive or flash activity, spindle-shaped flashes recorded in a state of natural sleep. It also occurs during certain neurosurgical and pharmacological interventions. A characteristic feature of the sigma rhythm is the increase in amplitude at the beginning of the sigma rhythm burst and its decrease at the end of the flash. The amplitude varies, but in adults it is generally at least 50 µV. The Sigma rhythm appears in the initial stages of slow-wave sleep, which immediately follows drowsiness. During sleep with delta waves, the sigma rhythm rarely occurs. During the transition to REM sleep, the sigma rhythm is observed in the EEG, but is completely blocked in the developed phase of REM sleep. In humans, this rhythm occurs from about three months of age. With age, the frequency of rhythm fluctuations, as a rule, does not change.

Instant relaxation and stress relief- frequencies between 5 and 10 Hz are used for different levels of relaxation.

Sleep replacement- a thirty-minute session at 5 hertz replaces 2-3 hours of sleep, allowing you to wake up early in the morning more alert, listen for half an hour before falling asleep and getting up in the morning.

Fighting insomnia- waves between 4 and 6 hertz in the first 10 minutes, then moving to frequencies below 3.5 Hz (for 20-30 minutes), gradually descending to 2.5 Hz before ending.

Raising tone- theta waves (4–7 Hz) 45 minutes a day.

Stimulation of brain rhythms

Let's look at ways available to every person to stimulate brain rhythms to improve natural abilities, including memory and creative insights.

Alpha rhythm stimulation

People have different levels of alpha wave production. For some, the level of these waves is naturally very low, for others, on the contrary, it is high. In children, alpha and theta waves predominate. Therefore, children do not need alpha rhythm stimulation.

As we grow older, our brains begin to produce more beta waves. Psychologists say that the alpha rhythm predominates in extroverts (outgoing optimists who easily interact with society) and is significantly reduced in introverts (restrained, slightly shy and withdrawn people focused on their inner world). Stimulation of alpha waves helps introverts feel more confident in society.

Ways to increase alpha rhythm are:

1. Synchronization of waves with external signals. It consists of listening to certain tracks made up of stereo signals (see more details below).
2. Daily meditation-relaxation- requires practice and time. For beginners, it is enough to devote 20 minutes a day to training to learn how to relax.
3. Yoga- promotes complete relaxation of the body and increases the level of alpha waves. Proper and constant yoga practice will help you consciously control your alpha rhythm.
4. Deep breathing- a method of saturating brain cells and the body with oxygen. By mastering this method and making it a habit, you will help your brain automatically tune in to the alpha rhythm.
5. Visualization. As soon as we close our eyes and start dreaming, drawing positive images, our brain immediately begins to actively produce alpha waves.
6. Alcohol- an effective, but most unhealthy way to increase. People easily get used to relieving stress with alcohol. When taken, there is a sharp increase in the production of alpha waves, resulting in a state of relaxation and tranquility. That is why, by stimulating alpha waves with special equipment, you can do the opposite - treat alcoholism and drug addiction.

Negative effects that occur with excessive stimulation of the alpha rhythm include increased drowsiness, fatigue, and even depression. It is important to understand your condition. If you feel tired, sleepy and starting to feel depressed, it means that your brain needs stimulation not from alpha waves, but from beta waves.

Increasing the alpha rhythm will be useful in cases of depression associated with fear, nervousness and tension. There is no need to increase the alpha rhythm in a calm, relaxed state with a clear mind. This can lead to feelings of disappointment, boredom, and loss of interest in life. When these effects occur, you need to stop alpha wave stimulation and increase the beta rhythm.

Beta rhythm stimulation

How does stimulating the brain with beta waves benefit a person? These waves naturally begin to dominate conversation and learning activities. Increasing the beta rhythm improves social skills, mental abilities, raises energy levels, sharpens the senses, and concentrates attention. Researchers have found that people with above average IQ have increased brain production of beta waves. This is not surprising, because these waves speed up brain function and increase the perception of educational information. Beta stimulation is useful for those who feel tired and overwhelmed during the day.

Ways to stimulate beta waves:

1. Wave Synchronization- using music containing binaural beats (see more details below).
2. Reading interesting books- increases the activity of the left hemisphere and the production of beta waves.
3. Caffeine- enhances beta waves, but only for a short time. Energy drinks and smoking, which are harmful to the body, cause a surge in wave activity. However, soon after getting up, you will feel a sharp drop in energy and spend the rest of the day in a broken state.

Disadvantages of increasing beta rhythm. If you have naturally elevated levels of beta waves, then additional stimulation will lead to feelings of fear, unexplained anxiety and even panic. The beta rhythm increases muscle tension and blood pressure. These waves affect the processes of excitation of the nervous system and relieve drowsiness. Therefore, hypertensive patients and those suffering from insomnia should not get carried away with stimulating beta waves.

Theta Wave Stimulation

The theta rhythm brings our body into a state of deep relaxation, during which we dream. These waves are a thin border between consciousness and subconscious. Under their influence, self-healing mechanisms are launched in the body, and physical and spiritual condition improves. Thanks to deep relaxation with the theta rhythm, our body quickly recovers after heavy exertion.

Entering the theta rhythm state contributes to the emergence of a deep connection with the subconscious and the emergence of paranormal abilities (exit of consciousness beyond the physical body, establishing contact with the other world, extrasensory perception). Staying in it brings us feelings of bliss and peace.

Psychotherapists use instrumental and other theta wave stimulation to treat patients for mental trauma. The principle of treatment is based on a person’s recollection of a traumatic event hidden in the depths of the subconscious and a change in attitude towards it.

Greater theta wave activity is found in children and creative people. The theta rhythm awakens and strengthens our emotions and feelings, allows us to program the subconscious, and get rid of negative thinking.

Ways to stimulate theta waves:

1. Synchronization of the brain with special rhythms.
2. Listening to pleasant music. The sounds of such music are associated with the production of emotions and sensations, and this is a direct way to increase the activity of theta waves.
3. Meditation (light relaxation and dhyana with some absorption)- produces alpha and theta rhythm. The easiest way is to learn how to produce alpha waves, and only after positive training comes the ability to control the theta rhythm.
4. Hypnosis and self-hypnosis. Allows you to strengthen the alpha and theta rhythm.
5. Yoga- helps to consciously control the state of theta waves and extract maximum benefit from it.

Unhealthy ways to increase theta rhythm include taking hallucinogenic drugs and alcohol. In a state of alcoholic intoxication, the activity of alpha waves first increases, a feeling of peace and relaxation sets in, then a phase of violent activity begins - beta rhythms, then they are replaced by theta oscillations. Chronic alcoholics experience constant theta activity, which impairs their speech, memory, and thinking abilities.

Mindful meditation, yoga and hypnosis help a person to know himself, immerse himself in the subconscious, and learn to produce alpha and theta waves.

Disadvantages of increasing theta brain activity include:

• Theta stimulation is not suitable for dreamy people who are prone to fantasizing, as it will make them even more distracted.
• An increase in the theta rhythm leads to decreased concentration and drowsiness. Therefore, you should not stimulate theta waves before work. Just like alpha, theta oscillations in large quantities cause apathy and boredom.

Delta Wave Stimulation

Stimulating delta waves is the most difficult process, since delta waves “shape” the subconscious and in the subconscious. Ordinary people are in a state of delta rhythm dominance only in deep sleep, coma or unconsciousness. Only experienced healers, psychics, shamans, and experienced meditators can consciously control delta oscillations. Without studying special techniques and methods, without a competent assistant, it is not recommended to increase delta brain activity on your own.

The easiest way to achieve sustained delta waves is to breathe rhythmically at a rate of about 60 breaths per minute.

This method is used by shamans in ritual dances before going to the “subtle” world for answers to their questions.

Synchronization of waves with external signals

Our brain has the ability to synchronize its dominant frequency with an external signal, this is called "frequency response." This makes targeted brainwave synchronization possible—the targeted use of sound or light to synchronize the frequency of the electrochemical activity of the brain with a frequency corresponding to the desired state of the brain.

The main types of sounds used for brain wave synchronization (BWS):

Binaural beats are two tones that have slightly different speeds (or frequencies) and are delivered separately to each ear. These rhythms are perceived as if they arise directly in the head. In this case, the brain begins to work at a frequency that is obtained by combining these two frequencies. Headphones are a must because there is no other way to deliver a specific sound to each ear in isolation.

This effect is produced in the brain, and not in the ears, as is the case with monaural rhythms. It is a mixed product of the activity of neurons located in the ear and the brain. Binaural beats are different from monaural beats, which are generated in the environment (external to the ear), like strumming two guitar strings at slightly different frequencies at the same time.

This is how a binaural beat is generated:

Binaural beats were first discovered in 1839 by a German experimenter (H. Dove). At that time, binaural beats were considered a type of monaural beats. Monaural and binaural beats are rare in nature, but often appear in man-made objects.

Binaural beats are not too noticeable, since the modulation depth (the difference between loud and quiet sound) is 3 db. This means that binaural beats do not produce any significant SMV, but have a hypnotic and relaxing effect.

This happens in part due to the Ganzfeld effect. The Ganzfeld effect is a process where the mind calms down as a result of monotonous exposure to the senses.

A natural example of the Hanzfeld effect would be when you are sitting in a field in a village, staring at the spacious blue sky and listening to the rustling of leaves on the trees (white noise) away from the bustle and other manifestations of city life.

Thanks to the Hanzfeld effect, binaural beats, as a psychological tool, rather play an assisting role in the generation of the SMV process, the goal of which is peace of mind and soul.

Monaural rhythms arise in the ears as a reaction to sounds of a different nature. Like binaural beats, these sounds are not found in nature, but are common when listening to machinery that constantly produces sound. For example, you might hear two engines running creating a resonance effect in a building. At the same time, you can literally feel the vibrations with your whole body that occur when the sounds of these engines “collide” with each other.

Musicians use monaural rhythms to tune string instruments. Both monaural and binaural rhythms are the result of the arithmetic sum of the waveforms of two tones, while they complement or “negate” each other, becoming louder, then quieter, and louder again.

This is how a monoural rhythm is generated:

Isochronous tones- These are directly spaced tones that turn on and off very quickly. Synchronization occurs due to the rhythmic switching on and off of sounds of a certain frequency. Isochronic tones are currently considered the most effective means of auditory stimulation, and are recognized as more effective for synchronization than monaural and binaural beats. They cause a strong reaction and appeal to most people.

Isochronic tones, consisting of pure tone (complex waves), with a frequency of 150-180 Hz show the best personal perception result so often that they are recommended for general use.

Unlike binaural beats, isochronic sounds can be heard through external speakers, or listened to with the whole body. The brain perceives sound not only through the ears, it perceives signals coming from the whole body.

Isochronous sounds do not require headphones, but using headphones can produce a clearer effect by eliminating external sound interference.

It is assumed that isochronic tones also have hypnotic properties, however, this does not mean that they inspire any ideas or additional affirmations. These are vibrations that help you relax, meditate deeper and work with your subconscious, for example, when clearing it.

A quick overview of the three types of sounds to sync with

1. Binaural beats: Two sounds that are slightly different in frequency create a frequency to synchronize. Headphones are used when listening; one sound goes to the left ear, the other to the right, exactly at the same time. The brain begins to work at a frequency that is obtained by combining these two frequencies. You hear not two sounds, but one. Headphones are a must because there is no other way to deliver a specific sound to each ear in isolation (both ears hear both sounds and the brain starts working at the desired frequency).

   And although some say that binaural beats are not as effective for synchronization as monaural or isochronic sounds, binaural beats are more effective for synchronizing the hemispheres of the brain. It is believed to promote clarity of thought and is characteristic of the thinking of geniuses, where logic and creativity are used in equal measure.

2. Monaural rhythms: monaural rhythms occur in the ears as a reaction to sounds of a different nature. Like binaural beats, these sounds are not found in nature, but are common when listening to machinery that constantly produces sound. For example, you might hear two engines running creating a resonance effect in a building. At the same time, you can literally feel the vibrations with your whole body that occur when the sounds of these engines “collide” with each other.

   Or perhaps you've heard two guitar strings tuned to different frequencies sound at the same time: you hear the frequency of consonance, not two different frequencies. No headphones are required for monaural rhythms.

3. Isochronous sounds They pulsate very quickly, turning on and off rhythmically. The synchronization frequency is obtained very simply - by repeatedly turning on and off the sound of the desired frequency. Isochronous sounds do not require headphones, but using headphones can produce a clearer effect by eliminating external sound interference. Experts generally agree that isochronic sounds may be more effective for synchronization than monaural and binaural beats.

Isochronous sounds are felt by the body, and not just heard by the ears.

Unlike binaural beats, isochronic sounds can be heard through external speakers, or listened to with the whole body. The brain perceives sound not only through the ears. Have you ever felt the rhythm with your whole body - for example, at a rock concert? Even the deaf can “hear” sounds by feeling the vibrations with their bodies rather than with their ears.

Both the brain and body perceive (“hear”) constant external stimuli. Isochronous sounds are a relatively new technology, which replaced binaural and monaural beats, which have been used for about a hundred years. You can achieve a deeper synchronization effect with isochronic sounds than with binaural beats due to the synchronization of the whole body.

Are isochronic sounds safe? Yes. Brain synchronization is not brainwashing! The brain naturally tends to synchronize with any repeated sound. Sounds influence the electrochemical activity of the brain in the same way that listening to repeated light drum patterns evokes relaxation. It only affects your mood and your state of consciousness - brainwave synchronization does not inject any thoughts or ideas into your consciousness, nor does it cause physical harm.

Note. In short, the essence: planets are not needed at all in astrology, there are simply cycles (rhythms) in the world to which everything in it is tied, or with which everything in it is synchronous (resonant) - you can calculate these rhythms by finding some common cycles in a person and something more or less permanent and global (if the nightingale outside the window has a global cycle, all astrology can be perfectly tied to the nightingale).

To understand the theta state, you first need to understand brainwave theory. There are five different frequencies that our brains can operate at: beta waves, alpha waves, theta waves, delta waves and gamma waves. The frequency characteristics of our brain are constantly changing as it constantly emits waves in all frequency ranges. Everything you do and say is controlled by the wave frequency of your brain activity, which in any given situation will prevail over its other frequencies.

As you know, our brain consists of a huge number of neurons interconnected by synaptic connections. By interacting through these connections, neurons form electrical impulses that control the activities of our entire body.

Gamma – vibration frequency above 30 hertz;
Beta - from 14 to 30 hertz;
Alpha - from 8 to 13 hertz;
Theta – from 4 to 8 hertz;
Delta – below 4 hertz.

For example, the brain emits 13 hertz (that is, in the range from high alpha to low beta waves) when we are in a state of active mental activity. It has been proven that when a person has difficulty learning and concentrating, he has a deficiency in the emission of waves of this frequency in certain areas of the brain responsible for such activity.

Gamma waves, above 36 hertz. Gamma waves are the only ones that the brain generates everywhere, that is, they are not recorded in separate areas, but in every point of the head. It is believed that when a person needs a simultaneous integral connection with information from his various stores, the brain generates gamma waves. Good memory corresponds to gamma waves of 40 hertz, and their deficiency leads to a decrease in the ability to remember. The effect of training “gamma states” is not announced by official science and is considered to be unknown.

Beta waves, 14 – 30 hertz. Beta waves are “fast” waves and are always recorded, that is, they are considered normal, when the eyes of an adult are open and his state can be called alert, that is, actively involved in the outside world with conscious or unconscious increased attention, excitement or excitement. Every time you think, speak, or interact with anyone, your brain operates in the beta frequency range. In a state of predominance of beta waves, a person is active, his attention is directed to the world around him and the events occurring in it. Almost every person in modern society is in this state of dominance of beta waves every day, and we can say that the “beta state” is often a “near-stressful” state.

Beta waves are divided into 3 groups:
Low beta waves: 13-16 hertz. This state is characterized by slight involvement in the outside world, that is, the person is no longer relaxed, but not yet very excited. Conscious training of low beta waves can develop skills of calm concentration and conscious control of attention.

Medium beta waves: 16-18 hertz. This state is characterized by awareness of oneself and the outside world and involvement in it, that is, the person is already excited, but not yet stressed. Their conscious training can develop various mental abilities, for example, focusing on one thought. IQ growth is impossible without training these waves.

High beta waves: 18 – 30 hertz. This state is characterized by excited involvement in the outside world. Thus, beta waves can be associated with increased vehicle speeds and the use of these speeds in various modes - both for quickly reaching a destination on congested city roads, and for an adrenaline-pumping race without a speed limit on night highways!

Alpha waves, 7-14 hertz. Although alpha waves lie in the range of 7.5 - 14 hertz, it is believed that their normal frequency in a healthy person is 10 hertz. This rhythm is considered normal for an adult who is in an active, but at the same time relaxed and comfortable psychophysical state, when attention is not greatly distracted by incoming information and its processing. In this state, the alpha rhythm dominates in people aged 13 years and older.

The state of predominance of alpha waves is a transitional state - a kind of bridge between beta and theta frequency characteristics of brain function. Being in the alpha state is characterized by a very relaxed, meditative state of mind. In such a state, real visions come to a person; these same waves are responsible for our dreams and fantasies. This state involves a much less focused and distracted view of the world.

People whose brains do not function well in this range usually have memory problems. For example, if you remember having a dream that impressed you, but cannot remember it, this indicates insufficient generation of alpha frequencies. This is why you fail to create a connection between your conscious and subconscious minds. To better understand being in the alpha state, close your eyes and imagine a sunset. Let your mind's eye see the sun setting in the ocean and seagulls hovering low not far from the shore. This is the beginning of entering the alpha state.

When energy healers working using the Reiki system were tested on an electroencephalograph, they found that they actively use alpha waves. Reiki practitioners connect their body to an energy source and then use their hands to direct this energy to heal patients. The electroencephalograph showed that when Source energy enters the healer's body and is then redirected through the hands to heal, his brain is in the alpha phase. It is known that the alpha state can relieve pain, and it is actively used in healing.

Scientists believe that alpha waves are generated by the white matter of the brain, which in turn connects all parts of the brain with each other. In the alpha state, a healthy person is able to effectively cope with any given task. At the same time, the basic level of alpha wave generation is higher in extroverts than in introverts. The alpha frequency of the brain is very important for learning and assimilation of new information, and is also associated with creative problem solving, creativity and mental functioning. When a person’s alpha rhythm is normal, he is in a good mood and sees the world positively. The easiest way to increase alpha waves is by closing your eyes and breathing deeply and calmly, and to decrease them by, for example, starting to count to yourself. Training alpha-theta rhythms leads to balance, self-control, develops abstract thinking and voluntary control of attention.

Theta waves, 4-7 hertz. They appear in a very calm state of mental activity and theta waves usually correspond with states such as remembering, daydreaming and fantasizing. It is believed that theta waves connect the conscious and subconscious mind, and in order to access the storehouse of this information, it is necessary to develop the amplification of these waves. Theta waves increase during concentration on the inner world, meditation, prayer and other spiritual practices.

Theta phase is a state of very deep relaxation. In this state, brain waves slow down to 4-7 vibrations per second. Hermits have to meditate for many years to become deeply immersed in the theta state, and once there they achieve full awareness. Theta waves belong to our subconscious; they are responsible for that part of our brain that is between consciousness and unconsciousness. This is the place where our memories and experiences are stored. Theta waves are also responsible for our attitudes, beliefs and behavior.

When theta waves predominate, a person experiences creative uplift and inspiration, and his experiences are sublimely spiritual in nature. In the theta state we really know that God exists, it is absolutely clear to us that He exists. When we call upon the Creator in the theta state, we are reunited with Him. When you imagine leaving your body through the higher chakra while practicing Theta Healing, your brain is still operating in the alpha range, which is reflected in the EEG readings. However, when consciousness soars above the highest chakra and begins to seek a meeting with God, the encephalograph shows that brain activity automatically switches to working in the theta range. It is believed that adults do not generate enough theta waves in an active everyday state and emit them only in their sleep, but children under 13 years of age live in an excess of theta waves. Theta wave activity has also been linked to the activity of the lymphatic system.

When the theta rhythm of the brain corresponds to the norm, a person feels calm and peaceful. When we are under stress or negative emotions, the level of theta waves diagnosed is very low. Training to enhance theta waves allows you to consciously enter meditative states, adjusts the mind-body connection, and also increases the ability to quickly concentrate and manage attention.

Delta waves, 0.1 – 4 hertz. The lowest recorded brain frequency is the delta frequency. These are the highest in amplitude and slowest in frequency waves. The human brain emits waves of this frequency in a state of deep sleep or in so-called trance states. Delta waves are associated with states when we are involved with interest in some process. These waves dominate brain activity in children under one year of age. It is believed that delta waves are associated with our unconscious mind, and to receive information from this area we must strengthen the delta waves in order to become unfocused with the physical world around us. If we need to achieve a high degree of concentration and focus on any task, then the delta waves must be weakened. Training in strengthening delta waves allows us to consciously enter states of very deep relaxation and trance states.

Brain biorhythms work differently in different functional states of human consciousness. Their frequency constantly changes throughout the day. If a person closes his eyes, the brain automatically enters the sleep stage, preparing the body for proper rest. Upon awakening, brain activity increases, the frequency of wave oscillations intensifies.

Thanks to special equipment, scientists record an electroencephalogram in real time, taking readings from the left and right hemispheres. Where you can clearly see how brain activity changes in different states of consciousness.

Biorhythms are measured in two indicators:

• Amplitude – pulse frequency, measured in microvolts;
• Frequency is the maximum pulse rate per second, measured in hertz.

The following five rhythms of brain function are distinguished:

• Delta rhythms – low frequency (0.5-4 Hz);
• Theta rhythms – low frequency (4-8 Hz);
• Alpha rhythms – mid-frequency (8-14 Hz);
• Beta rhythms – high frequency (14-38 Hz);
• Gamma rhythms are high frequency (38-55 Hz).

Delta rhythms – sharpen intuition

During deep, dreamless sleep, Delta rhythms predominate. It is at the moment of greatest activity of these waves that the human body recovers during sleep. Although during wakefulness they do not stop functioning, interacting perfectly with other waves of brain activity. They are also responsible for the connection between consciousness and subconscious. It happens that a person intuitively feels what to do, without understanding the nature of his feelings. This is a consequence of the active activity of Delta rhythms.

If a person has well-developed Delta waves, this manifests itself in the following:

• Strongly developed sense of danger;
• The ability to feel someone else's pain;
• The right decisions are made quickly;
• Heightened intuition;
• Hear hints from the subconscious;
• Sometimes, the ability to predict events manifests itself.

With an excess of Delta rhythms, it is difficult for a person to distinguish his own emotions from others. He takes everything to heart, constantly feels guilty, wants to help everyone, even to the detriment of his own interests.

Theta rhythms – state of relaxation

When a person is on the verge of sleep and reality, Theta rhythms are most active. They promote vivid dreams and help assimilate information received during the day. In a meditative state and during self-hypnosis, it helps to find harmony between one’s own “I” and the subconscious.

When Theta rhythms are activated, the following occurs:

• Visualization of vivid images;
• Unexpected ideas come;
• Unity of soul and body;
• Dreams filled with deep meaning;

By stimulating the work of Theta rhythms through meditation, you can achieve an enlightened state, improve memory and activate brain activity.

Alpha rhythms – “flight” of consciousness

You can escape reality by plunging into the Alpha state. This is a kind of threshold between real events and dreams. The person relaxes, closes his eyes, Alpha rhythms are activated, and visualization of images occurs most clearly.

Alpha rhythms also contribute to:

• Assimilation of new information;
• Muscle response increases several times;
• The hormone of joy is released;
• Pain is reduced.

With a lack of Alpha waves, it is impossible to remember dreams, and communication with the subconscious is lost. Scientists have proven that Alpha rhythms are activated immediately as soon as a person closes his eyes.

Beta rhythms – the state of wakefulness

After awakening, a person is under the influence of Beta waves most of the time. They are responsible for the thought process, helping to concentrate attention. With anxiety, panic, fear, blood pressure rises, the pulse quickens - this is all a consequence of an overabundance of Beta rhythm activity.

If Beta rhythms dominate for a long time:

• Increases sensitivity;
• Obsessive thoughts appear;
• There is a feeling of discomfort;
• The reaction worsens.

At the same time, with a lack of Beta rhythms, depression, memory impairment, and inattention are possible.

Gamma rhythms – touching the higher consciousness

These rhythms are active only in the waking phase; during sleep they are completely turned off. The highest frequency rhythms contribute to the development of creative potential. The person is in emotional arousal and ready for active action.

If through long meditations you achieve a large amplitude of gamma rhythms, then you can come into contact with the higher mind, combine all your mental and physical sensations into a single conscious experience.

Active Intelligence

A state when everything becomes clear, decisions are made at lightning speed, and problems seem trivial. A person feels enlightened, the world is suddenly illuminated with unprecedented light. The condition is called active intelligence. It occurs when four rhythms function simultaneously in the correct proportions:

• Thoughts are clear and understandable (Beta waves);
• It is easy to manage feelings and emotions (Alpha waves);
• Information is instantly absorbed (Theta waves);
• Developed intuition (Delta waves).

This state is often achieved by people who are passionate about the process when doing what they love.

Having learned to control biorhythms, reduce them at will. A person can achieve a changed consciousness and radically improve his life. The main key is to learn to enter a state of peace. At the initial stage, it is enough to close your eyes and activate the Alpha rhythm. Further, with the help of meditation, you can gradually reveal your potential and expand the boundaries of consciousness.

The human brain is a complex system that operates with electrical signals. Neurons that create and conduct nerve impulses react in unison, creating “swinging” electrical discharges that set the rhythms of the brain, called “waves.”

Human consciousness, in turn, is a reflection of the mixture of different rhythms. Let's figure out what the alpha rhythm is and how beneficial it is for health.

Brain rhythms are divided into six types - α (alpha), β (beta), γ (gamma), δ (delta), θ (theta), σ (sigma).

The alpha rhythm is a rhythm of electrical activity in the brain, located in the frequency range from eight to thirteen hertz and with an average amplitude of oscillations of thirty to seventy microvolts.

The maximum amplitude value is observed when a person is conscious, but in the most relaxed state, for example, in the dark with his eyes closed. With increased mental activity or increased attention, the amplitude of the oscillations decreases until they disappear completely.

Alpha rhythm

The generation of the α-rhythm occurs against the background of a person’s study of images accompanying the solution of a problem that worries him, with maximum concentration of attention.

For your information: in the vast majority of cases, α-brain waves completely disappear the moment the eyes open.

The character features of the human α-rhythm are closely related to heredity and are established during the period of intrauterine development.

People with a pronounced α-rhythm tend to operate with abstract concepts and solve problems of the corresponding type. On the contrary, the absence of α-waves even with completely closed eyes indicates possible difficulties in solving problems that are of an abstract nature, against the background of freely operating with any visual images.

For your information: the brain in α-mode is capable of processing large flows of information, which allows a person to find new, sometimes original options for resolving existing problems.

Beta rhythm

The beta rhythm is a rhythm with an amplitude of five to thirty microvolts and a frequency of fifteen to thirty-five vibrations per second. Brain activity of this kind is observed during the period of active wakefulness and increases against the background of any activity, with increased concentration, violent expression of emotions, and intellectual stress.

By generating β brain waves, the brain resolves various problems, processes situations that gave rise to stress, and solves variable tasks that require full dedication. It was this type of brain activity that allowed people to achieve everything that humanity is proud of.

Gamma rhythm

The gamma rhythm is a rhythm with an amplitude of less than fifteen microvolts and a frequency of thirty to one hundred vibrations per second.

By producing these waves, the brain solves problems that cannot be solved without maximum concentration, composure and concentration.

Delta rhythm

The delta rhythm is a rhythm with an amplitude of twenty to two hundred microvolts and a frequency of 0.5-4 vibrations per second. Delta waves are observed:

• during a period of deep sleep of a natural nature, occurring without dreams;
• in coma;
• during conditions caused by the use of narcotic substances;
• when recording electrical signals from areas of the cortex in contact with an injured area of ​​the brain or a neoplasm;
• at rest against the background of stressful situations or prolonged work requiring serious intellectual effort;
• in people who meditate using the Dhyana technique.

Theta rhythm

The theta rhythm is a rhythm with an amplitude of twenty to one hundred microvolts and a frequency of four to eight hertz. Theta waves are strongest in children aged 2-5 years.

Such brain activity helps improve memory, fully assimilate knowledge received from outside, and develop talents. This is why children process and assimilate a huge amount of information, which is not typical for teenagers and adults (theta waves appear in them only in the REM sleep phase, half asleep).

Sigma rhythm

Sigma rhythm is a rhythm with an amplitude of more than fifty microvolts and a frequency of ten to sixteen hertz, accompanied by fusiform activity (bursts) and generated in a state of natural sleep, as well as under the influence of certain medicinal or neurosurgical influences.

A feature of such brain activity is an increase in amplitude in the initial period of activity and its decrease in the final period. Sigma waves are observed in the initial stages of slow-wave sleep, which replaces drowsiness.

Note: Sigma waves are generated by the brain from approximately three months of age. As you grow older, the frequency of oscillations remains virtually unchanged.

Let's look at what the alpha rhythm of the brain is in more detail.

Alpha rhythm: norm and deviations

The alpha rhythms of a person who does not have health problems are rhythms with a frequency of eight to thirteen hertz and an amplitude of alpha waves of thirty to seventy microvolts. Pathological deviations from the norm are considered:

• persistent α waves found in the frontal lobes;
• interhemispheric asymmetry exceeding thirty percent;
• rolandic or paroxysmal rhythm;
• violation of the sinus wave pattern;
• wave amplitude is too low or too large;
• rhythm index less than fifty percent;
• variable frequency.

Any deviations require diagnosis and timely treatment.

The importance of alpha rhythm for the brain

The alpha rhythm of the brain is set by low frequency waves generated by its cells during a period of absolute relaxation. It has been proven that a person’s stay in this state restarts the central nervous system and relieves stress that has accumulated throughout the day due to exhausting work activity. Moreover, according to many experts, most scientific discoveries were made by people under the influence of α waves.

The main purpose of α-rhythms is:

• processing information received and accumulated during the day;
• restoration of the body's vitality by activating the parasympathetic nervous system;
• improvement of cerebral circulation;
• inhibition of excessive activity of the limbic system;
• elimination of the consequences of being in stressful situations (vasodilatation, normalization of the immune system);
• activation of the functions of the hypothalamus, which ensures the regenerative properties of the body.

In addition, α-rhythms produced by the brain at rest relieve the excitation of the limbic system, which is responsible for the basic needs of the body. Its overexcitation can lead to the development of specific changes in the psyche and addictions - smoking, alcoholism, bulimia, as well as disturbances in the menstrual cycle and disorders in the functioning of the endocrine system.

A decrease in the activity of alpha waves in the brain increases the risk of developing heart and vascular diseases (angina, hypertension), cancer, and disorders of the immune system.

Moreover, people with a reduced frequency of waves of this type cannot think positively, which, in turn, leads to fixation on existing problems and, accordingly, to difficulties in resolving them.

Causes of alpha rhythm disturbance

Disturbances of the α-rhythm are observed primarily in people who have crossed the sixty-year mark. This is explained by a deterioration in blood circulation in the brain and is accompanied by a decrease in the amplitude of the waves.

In addition, changes in brain activity indicators may be accompanied by the following pathologies:

• essential hypertension, epilepsy, including that developed due to drug use (in such situations, direct asymmetry of frequency and amplitude in the left and right hemispheres of the brain is diagnosed);
• hypertension (manifested by a decrease in rhythm frequency);
• oligophrenia (accompanied by an increase in α-wave activity);
• tumors of various origins, cysts, pathologies of the corpus callosum (characterized by asymmetry between the cerebral hemispheres, reaching 30%);
• deterioration of blood circulation.

For information: in order to assess alpha activity in vegetative-vascular dystonia, depression, head injuries, dementia of various origins, disorders of the emotional-volitional sphere, hypertension, headaches, vomiting, an electroencephalogram is used.

Positive effects of alpha rhythm on humans

The work of the brain in the α-rhythm is accompanied by absolute calm and relaxation of the person. This state is the most beneficial for the body due to the fact that the central nervous system includes functions such as self-healing and self-regulation, which increases the performance of the brain and has an overall positive effect on the mental state.

In addition, α-waves:

• increase blood circulation in the brain, accelerating the flow of oxygen and nutrients;
• accelerate the regenerative functions of the body seven times;
• improve energy circulation;
• increase the ability for analytical thinking and, accordingly, minimize the time required to solve certain problems;
• provide the opportunity to reprogram the consciousness in order to get rid of psychological problems - insomnia, increased anxiety, overexertion, bad habits.

In addition, the functioning of the brain in the described mode makes it possible to suppress conditions that have developed against the background of everyday problems, strong emotional shocks, and childhood traumas, which, in turn:

• improves quality of life;
• increases the ability to perceive and process information;
• restores the vitality of the body;
• reduces the risk of developing various diseases:
• allows you to relax.

Please note: drug addiction and alcoholism can completely suppress the alpha rhythms of the brain.

Ways to Stimulate Alpha Waves

Increased α-wave activity is accompanied by complete physical and psychological relaxation of the body. Being under the influence of the described rhythm, a person is distracted from existing problems and almost completely gets rid of the consequences caused by stress.

Thought processes occurring in the brain slow down, which leads to a “cleansing” of consciousness.

Against the background of increasing α-waves, the following changes occur:

1. Relaxation of body and mind. The waves contribute to a person’s transition to a state of complete relaxation and peace. Intellectual processes slow down, consciousness becomes clear. The muscles are completely relaxed, fatigue and tension are relieved. A person enjoys relaxation and is distracted from existing problems and worries.
2. Transition to a creative mental state. Alpha waves are responsible for the creativity of human consciousness. As a rule, people of certain professions - musicians, artists, poets, writers - are in a similar state.
3. Improved problem solving abilities. Hard work and long hours of concentration trigger the beta rhythm, accompanied by a “mental block” known as creative block, in people of relevant professions. Stimulation of α-waves allows you to get out of the described state and finish the job you started.
4. Stabilization of the emotional background. The α-rhythm state is characterized by a balanced emotional state - constant mood and optimism. Stimulation of α-waves allows you to balance the mood of hyperactive people with unstable emotions, significantly improving their quality of life.
5. Improved physical condition. Alpha waves have a beneficial effect on the functioning of the human body. It has been established that the most suitable frequency for achieving success in sports is a frequency of ten hertz.
6. Reducing anxiety levels and reducing the effects of stress. Strengthening α-waves leads to a significant decrease in tension, the disappearance of fears, nervousness and anxiety.
7. Increased ability to work. Stimulation of the α-rhythm allows a person to concentrate on the actions being performed and to be completely immersed in work.
8. Switching to super learning mode. Switching to the α-rhythm mode allows you to learn something without much effort. The special activity of the brain in this case makes it possible to increase a person’s natural ability to perceive a large amount of information.
9. Strengthening the immune system. Strengthening α waves heals and prevents the development of diseases by reducing the severity of the effects of stress and enhancing relaxation.
10. Transition to positive thinking. Relaxation achieved by enhancing α waves leads to positive emotions and, accordingly, a movement towards a good mood.
11. Increase in serotonin levels. Under the influence of α-waves, the neurotransmitter serotonin is released, the lack of which causes the development of depressive conditions.

How to Strengthen Alpha Waves

In order to enhance alpha waves, the following are used:

• sound waves. The simplest and most accessible method based on listening to music created from stereo sounds. Allows you not only to strengthen the α-rhythm, but also to enjoy the process;
• meditation, relaxation. Requires certain skills, practice and time to achieve a positive result. Systematic training allows you to completely relax and start the required rhythm of brain function;
• yoga. Its action resembles meditation and allows you to achieve complete relaxation of the body and immersion in the α-rhythm;
• correct breathing. It is based on the use of deep breaths, saturating the cells of the brain and other organs and systems with oxygen. Breathing deeply contributes to the natural restructuring of the body into the mode of reproduction of the alpha waves it needs;
• hot water baths. Relieves fatigue after a hard day at work, promotes relaxation of all muscles of the body;
• visualization. Closed eyes and the creation of imaginary images stimulate the activity of α waves and lead to their dominance over the rest;
• self-hypnosis. Allows you to reduce the wave range to values ​​​​corresponding to alpha and theta activity levels. Requires some training;
• watching TV shows. Thirty seconds spent in front of a blue screen can reduce the intensity of brain activity by stimulating α-activity.
• alcoholic drinks. Alcohol increases the production of alpha waves, which in turn relaxes and calms a person. It is often used by people to relieve stress.

The Dangers of Promotion

However, α-wave stimulation is not always beneficial. Against the background of the predominance of the α-rhythm, far from pleasant phenomena may appear.

Thus, people suffering from pathologies leading to attention deficit may worsen their health problems, which will lead to an even greater decrease in concentration.

α-rhythms are also dangerous for people suffering from depressive conditions that develop against the background of fatigue. Stimulation of α-waves in this case can lead to an exacerbation of the existing disease.

Another negative effect of exposure to α-waves is the need for rest during the day - experimenting with your own brain can result in the appearance of chronic fatigue and drowsiness, and constant stay in a half-asleep state is not conducive to a normal lifestyle.

In addition, with excessive stimulation of alpha waves, visual perception can be disrupted, increased sensitivity to information coming from outside can develop, and depression can begin.
Beyond that, some people simply don't need stimulation. This:

• extroverts with increased levels of α-waves;
• followers of Eastern practices who have meditation skills and constantly use them;
• children.

In conclusion

Alpha waves are of great importance in ensuring good general health of a person. Working the brain in alpha mode for twenty minutes a day has a beneficial effect on well-being, improves memory, relieves insomnia, and speeds up reactions.

A person feels an influx of vital energy, opens up new opportunities and feels absolutely happy.
