Recently, news spread across the country: the state corporation Rusnano is investing 710 million rubles in the production of innovative medicines against age-related diseases. We are talking about the so-called “Skulachev ions” - a fundamental development of domestic scientists. It will help cope with cell aging, which is caused by oxygen.

"How so? – you will be surprised. “It’s impossible to live without oxygen, and you claim that it accelerates aging!” In fact, there is no contradiction here. The engine of aging is reactive oxygen species that are already formed inside our cells.

Energy source

Few people know that pure oxygen is dangerous. It is used in medicine in small doses, but if you breathe it for a long time, you can be poisoned. Laboratory mice and hamsters, for example, live in it for only a few days. The air we breathe contains slightly more than 20% oxygen.

Why do so many living beings, including humans, need small amounts of this dangerous gas? The fact is that O2 is a powerful oxidizing agent; almost no substance can resist it. And we all need energy to live. So, we (as well as all animals, fungi and even most bacteria) can obtain it by oxidizing certain nutrients. Literally burning them like wood in a fireplace.

This process occurs in every cell of our body, where there are special “energy stations” for it - mitochondria. This is where everything we eat ultimately ends up (digested and decomposed to the simplest molecules, of course). And it is inside the mitochondria that oxygen does the only thing it can do - oxidize.

This method of obtaining energy (it is called aerobic) is very beneficial. For example, some living beings are able to obtain energy without oxidation by oxygen. Only thanks to this gas, the same molecule produces several times more energy than without it!

Hidden catch

Of the 140 liters of oxygen that we inhale from the air per day, almost all of it is used to obtain energy. Almost - but not all. Approximately 1% is spent on the production of... poison. The fact is that during the beneficial activity of oxygen, dangerous substances are also formed, the so-called “reactive oxygen species”. These are free radicals and hydrogen peroxide.

Why did nature even decide to produce this poison? Some time ago, scientists found an explanation for this. Free radicals and hydrogen peroxide, with the help of a special enzyme protein, are formed on the outer surface of cells, with their help our body destroys bacteria that have entered the blood. Very reasonable, considering that the hydroxide radical rivals bleach in its toxicity.

However, not all the poison ends up outside the cells. It is also formed in those very “energy stations”, mitochondria. They also have their own DNA, which is damaged by reactive oxygen species. Then everything is clear: the work of energy plants goes wrong, DNA is damaged, aging begins...

Precarious balance

Fortunately, nature took care to neutralize reactive oxygen species. Over billions of years of oxygen-rich life, our cells have generally learned to keep O2 in check. Firstly, there should not be too much or too little of it - both of them provoke the formation of poison. Therefore, mitochondria are able to “expel” excess oxygen, as well as “breathe” so that it cannot form those same free radicals. Moreover, our body has substances in its arsenal that are good at fighting free radicals. For example, antioxidant enzymes that convert them into more harmless hydrogen peroxide and just oxygen. Other enzymes immediately take up the hydrogen peroxide, turning it into water.

All this multi-stage protection works well, but over time it begins to fail. At first, scientists thought that enzymes that protect against reactive oxygen species weaken over the years. It turned out, no, they are still vigorous and active, but according to the laws of physics, some free radicals still bypass multi-stage protection and begin to destroy DNA.

Is it possible to support your natural defenses against toxic radicals? Yes, you can. After all, the longer certain animals live on average, the better their defenses are honed. The more intense the metabolism of a particular species, the more effectively its representatives cope with free radicals. Accordingly, the first way to help yourself from the inside is to lead an active lifestyle, not allowing your metabolism to slow down with age.

We train youth

There are several other circumstances that help our cells cope with toxic oxygen derivatives. For example, a trip to the mountains (1500 m and above sea level). The higher you go, the less oxygen there is in the air, and the inhabitants of the plain, once in the mountains, begin to breathe more often, it is difficult for them to move - the body tries to compensate for the lack of oxygen. After two weeks of living in the mountains, our body begins to adapt. The level of hemoglobin (the blood protein that carries oxygen from the lungs to all tissues) increases, and cells learn to use O2 more economically. Perhaps, scientists say, this is one of the reasons that there are many centenarians among the highlanders of the Himalayas, Pamirs, Tibet, and the Caucasus. And even if you only get to the mountains for a vacation once a year, you'll get the same benefits, even if it's just for a month.

So, you can learn to inhale a lot of oxygen or, conversely, a little, there are a lot of breathing techniques of both directions. However, by and large, the body will still maintain the amount of oxygen entering the cell at a certain average level that is optimal for itself and its load. And that same 1% will go to the production of poison.

Therefore, scientists believe that it will be more effective to approach it from the other side. Leave the amount of O2 alone and strengthen cellular protection against its active forms. We need antioxidants, and ones that can penetrate inside the mitochondria and neutralize the poison there. This is exactly what Rusnano wants to produce. Perhaps in a few years, such antioxidants can be taken like the current vitamins A, E and C.

Rejuvenation drops

The list of modern antioxidants has long been not limited to the listed vitamins A, E and C. Among the newest discoveries are SkQ antioxidant ions, developed by a group of scientists led by a full member of the Academy of Sciences, honorary president of the Russian Society of Biochemists and Molecular Biologists, director of the Institute of Physical and Chemical Biology. . A. N. Belozersky Moscow State University, laureate of the USSR State Prize, founder and dean of the Faculty of Bioengineering and Bioinformatics of Moscow State University Vladimir Skulachev.

Back in the 70s of the twentieth century, he brilliantly proved the theory that mitochondria are the “power plants” of cells. For this purpose, positively charged particles (“Skulachev ions”) were invented, which can penetrate into mitochondria. Now Academician Skulachev and his students have “attached” to these ions an antioxidant substance that can “deal with” toxic oxygen compounds.

At the first stage, these will not be “anti-aging pills”, but drugs for the treatment of specific diseases. First in line are eye drops to treat some age-related vision problems. Such drugs have already given absolutely fantastic results when tested on animals. Depending on the species, new antioxidants may reduce early mortality, increase average lifespan and extend maximum age - exciting prospects!

With oxygen starvation, the supply of oxygen to the brain through blood cells is disrupted

Cocktails, spray cans, pillows, devices and even mesotherapy are all popular methods of oxygen therapy. In the last decade, the number of residents of large cities who actively use means to prevent oxygen starvation has increased.

But does it really matter how much? oxygen in cells does it meet a certain level? Or have those who seek to increase their blood oxygen levels become victims of the marketing gimmicks of advertisers and manufacturers of newfangled but useless ideas?

The effect of increased oxygen in cells on humans

Subject to oxygen starvation (medically called hypoxia), the urban population suffers from

• drowsiness,
• frequent headaches,
• stress,
• rapid mood changes,
• powerlessness,
• sallow, gray or pale complexion,
• blurred vision,
• lack of sleep, etc.

Sometimes hypoxia itself becomes a symptom or consequence of other diseases, such as cardiovascular failure or bronchitis.

Is it possible that a simple lack of oxygen in the body is to blame? Let's figure it out.

First, let's decide why a person needs oxygen? On the one hand, even a child can answer this question: we breathe oxygen. On the other hand, the correct answer is much deeper, and it affects the vital processes of the entire human body.

Firstly, oxygen is involved in the generation of cellular energy. It converts nutrients (lipids, fats) into clean energy for the normal functioning of the cells that make up the tissues of all our organs. Without oxygen, at the cellular level our body would gradually stop doing its job, as a result of which a person’s immunity, mood, performance and well-being would deteriorate.

Secondly, oxygen helps remove toxic substances from the body. Have you noticed that usually in Hollywood movies, when the victim is being transported in an ambulance, they put an oxygen mask on him? This is done to increase the patient’s chances of survival by increasing the body’s resistance.

And finally, oxygen “carries” hemoglobin to cells, without which he cannot.

An oxygen-free environment will kill a person in 5 minutes, and reduced oxygen levels will have a strong and possibly irreversible negative effect on our body.

So, we found out that it is precisely thanks to sufficient content oxygen in the body we can lead a normal, happy life, full of joyful moments and the desire to act and develop. But there are several categories of citizens who are the most...

Oxygen is important for any living organism; even sea creatures cannot completely do without it. Nevertheless, among them, one needs oxygen more than others. For example, whales are closer to the water surface than jellyfish for this simple reason.

Although we noted that every city resident needs increasing oxygen in cells, depending on the type of activity and special situation, there are people for whom it is vital to maintain oxygen balance in their cells.

1. Athletes (professionals and amateurs).

The secret of an athlete’s success is in daily and often grueling training, which consumes the body’s resources at times higher than the life of an ordinary person. , the more oxygen is required to maintain the given pace.

The training process uses the strength of the whole body. During it, lactic acid (lactate) is also released, which in excess can disrupt the functioning of the liver, kidneys, central nervous system, brain and heart. Oxygen neutralizes the side effects of lactate, allowing athletes, both professional and amateur, to continue training and achieve visible results.

1. Pregnant women.

The lack of oxygen in the baby in the womb occurs due to the low oxygen content in the placenta, which comes there from the blood of the pregnant woman. Lack of oxygen in a pregnant woman in almost all cases affects the baby in her womb. Approximately 15% of pregnant women are diagnosed with oxygen deficiency. It is more important for the expectant mother to treat hypoxia, because in severe form, oxygen starvation can lead to

• premature birth,
• intrauterine fetal death,
• stillbirth,
• disability of the newborn.

Mostly, fetal hypoxia in a pregnant woman it develops as a result of her unhealthy lifestyle (using drugs and alcohol, smoking), stressful situations, health problems (heart, liver, kidneys, blood vessels, respiratory organs) and intoxication of the body.

1. Newborns and infants.

Medical statistics on oxygen starvation indicate that almost 89% of newborn children suffer from asphyxia, a type of hypoxia. Immediately after birth, doctors have a few minutes to clear the baby's airways and allow him to breathe air on his own. They then use the Apgar score to assess the severity of hypoxia. If the results are satisfactory, then the newborn will be observed for another 7–10 days, since it is during this period that various pathologies can be quickly identified and removed. In case it was not possible to diagnose or treat in time oxygen deprivation in an infant , then he may face many health problems, ranging from memory impairment and cognitive abilities to paralysis. Timely diagnosis at an early stage of pregnancy can save the life of not only the baby, but also his mother.

To summarize the above, we can say that the question “ Is it necessary to increase oxygen in cells?“at our modern pace of life, it should not stand at all. Methods of saturating the body's cells with oxygen are not always just a publicity stunt, some of them give effective results, and decide for yourself which one to choose. Take care of your health before it's too late.

Oxygen poisoning is a pathological symptom complex that develops after inhalation of gases or vapors with a high content of a common chemically active non-metal, mainly in the form of compounds. How does the substance affect the body? How serious is oxygen poisoning? What help can be provided to the victim? You will read about this and much more in our article.

In what cases is oxygen poisoning possible?

Oxygen toxicity is a fairly rare form of poisoning that cannot be obtained in the natural human environment. Because of this feature, many neglect the potential danger of this event and take it lightly. Potential circumstances that could lead to oxygen toxicity:

• Violation of rules for working with gas mixtures and equipment in production;
• Malfunction of equipment that supplies a substance to the human respiratory system under increased pressure - for example, oxygen masks in hospitals or airplane pilots;
• Failure to comply with recommendations on the necessary decompression measures for scuba divers and divers after working at great depths;
• Too frequent and prolonged oxygen barotherapy procedures.

As can be seen from the list described above, such circumstances are usually not typical and widespread; moreover, they are associated with an emergency situation - equipment breakdown, often along with non-compliance with basic safety rules. It should be understood that oxygen in its pure form is toxic to humans.

Why can't you breathe pure oxygen?

Oxygen is a key atmospheric element used by almost all living aerobes. It should be understood that air does not contain a pure substance, but a number of compounds.

In medicine, oxygen is used to improve the metabolic processes of the gastrointestinal tract, normalize the functioning of the cardiovascular system, disinfect and deodorize air masses, treat trophic ulcers, gangrene, provide pulmonary ventilation, study blood flow speed, and so on.

The physiological basis for the transport of a substance into the body is its penetration through the alveolar pulmonary membranes during inhalation and parallel binding with erythrocytes, which are the hemoglobin of red blood cells. The latter deliver oxygen to the soft tissues, are restored and add carbon dioxide located in the structures, which is later exhaled by the person.

The chemical intensity of oxygen saturation in the blood primarily depends not on the concentration of the gas, but on its pressure - the higher it is, the more substance will enter the plasma, after which it will pass into the soft tissues.

Oversaturation of the body with oxygen has its own medical term – hyperoxia.

With the formation of hyperoxia in severe cases, multiple disturbances in the functioning of the central nervous system, respiratory and circulatory organs can form. Not only pure oxygen, but also its individual reactive forms can cause potential harm in the form of toxic derivatives, for example, hydrogen peroxide, ozone, hydroxyl radical, singlet oxygen - in this case, tens of times smaller doses will be required to form poisoning.

Symptoms of oxygen toxicity

The symptoms of oxygen poisoning are not specific and significantly depend on the individual characteristics of the human body. Moreover, quite often the pathology is confused with other acute conditions accompanied by manifestations similar to hyperoxia.

Typical problems with quick or instant action (appear immediately):

• Dizziness;
• Slow breathing;
• Decreased heart rate, constriction of pupils and blood vessels.

A pathological excess of oxygen in the body creates the preconditions for an acute lack of hemoglobin, since the substance that penetrates the bloodstream through the lungs actively binds to it.

Typical problems of the middle period (from 10-15 minutes to half an hour):

• Intense increasing headache;
• Nausea and vomiting;
• Rapid redness of the face, limbs and skin on the body;
• Partial or complete numbness of the phalanges of the fingers and toes, twitching of the lips of the facial muscles;
• Weakening of olfactory and tactile reflexes;
• Serious breathing problems;
• Anxiety, irritability, aggressiveness, panic. Less often – stupor and lethargy;
• Fainting, convulsions and seizures.

First aid to the victim

If assistance is not provided to the victim for a long time, death can occur quite quickly. If you suspect hyperoxia, you should immediately call an ambulance. There are no effective mechanisms for first aid in this situation.. Possible actions may include:

• Immediately stop contact with highly concentrated oxygen and switch to regular air. If the necessary equipment is available, the person is allowed to breathe an oxygen-depleted mixture;
• Bringing the victim to his senses by any possible means;

• In the presence of convulsions, seizures and neurological manifestations, monitor the person’s condition and minimize the risk of damage to parts of the victim’s body (protect from damage, but do not secure the body with belts or other instruments);
• Artificial respiration and chest compressions in the absence of these two basic vital signs.

Inpatient treatment of patients with hyperoxia is symptomatic. Hardware support is used (ventilation, suction of foam from the lungs, etc.), and conservative therapy (from chlorpromazine to relieve seizures to diuretics).

Consequences for the body

Hyperoxia has the most serious consequences for the human body, depending on the concentration of oxygen, the pressure at which it entered the body, as well as other factors.

Potential problems due to oxygen overdose:

• From the bronchopulmonary system: pulmonary edema with the development of secondary bacterial infections, hemorrhages in the bronchopulmonary system, atelectasis, dysfunction of the spinal cord;
• From the side of the central nervous system. Persistent hearing and vision impairment, convulsive-epileptic seizures, pathologies of the brain and spinal cord;
• From the cardiovascular system: a sharp slowdown in pulse with a parallel drop in blood pressure, hemorrhages in the skin and various internal organs, the development of heart attacks and strokes, complete cardiac arrest.

If supersaturation with a high concentration of oxygen occurs at a pressure above 5 bar for at least several minutes, then the person almost instantly loses consciousness, super-severe hyperoxia rapidly develops, and death occurs.

In our body, oxygen is responsible for the process of energy production. In our cells, oxygenation occurs only thanks to oxygen - the conversion of nutrients (fats and lipids) into cellular energy. When the partial pressure (content) of oxygen in the inhaled level decreases, its level in the blood decreases and the activity of the body at the cellular level decreases. It is known that more than 20% of oxygen is consumed by the brain. Oxygen deficiency contributes. Accordingly, when oxygen levels drop, well-being, performance, general tone, and immunity suffer.
It is also important to know that it is oxygen that can remove toxins from the body.
Please note that in all foreign films, in the event of an accident or a person in serious condition, emergency doctors first of all put on an oxygen apparatus to the victim in order to increase the body’s resistance and increase his chances of survival.
The therapeutic effects of oxygen have been known and used in medicine since the end of the 18th century. In the USSR, the active use of oxygen for preventive purposes began in the 60s of the last century.

Hypoxia

Hypoxia or oxygen starvation is a reduced oxygen content in the body or individual organs and tissues. Hypoxia occurs when there is a lack of oxygen in the inhaled air and in the blood, when the biochemical processes of tissue respiration are disrupted. Due to hypoxia, irreversible changes develop in vital organs. The most sensitive to oxygen deficiency are the central nervous system, heart muscle, kidney tissue, and liver.
Manifestations of hypoxia are respiratory failure, shortness of breath; dysfunction of organs and systems.

Harm to oxygen

Sometimes you can hear that “Oxygen is an oxidizing agent that accelerates the aging of the body.”
Here, from the correct premise, the wrong conclusion is drawn. Yes, oxygen is an oxidizing agent. Only thanks to it are nutrients from food processed into energy in the body.
The fear of oxygen is associated with two exceptional properties of it: free radicals and poisoning due to excess pressure.

1. What are free radicals?
Some of the huge number of constantly occurring oxidative (energy-producing) and reduction reactions of the body are not completed to the end, and then substances are formed with unstable molecules that have unpaired electrons at the outer electronic levels, called “free radicals”. They try to grab the missing electron from any other molecule. This molecule, turning into a free radical, steals an electron from the next one, and so on..
Why is this necessary? A certain amount of free radicals, or oxidants, is vital for the body. First of all, to combat harmful microorganisms. Free radicals are used by the immune system as “projectiles” against “invaders.” Normally, in the human body, 5% of substances formed during chemical reactions become free radicals.
Scientists cite emotional stress, heavy physical exertion, injury and exhaustion due to air pollution, consumption of canned and technologically incorrectly processed foods, vegetables and fruits grown with herbicides and pesticides, ultraviolet radiation as the main reasons for the disruption of natural biochemical balance and the increase in the number of free radicals. and radiation exposure.

Thus, aging is a biological process of slowing down cell division, and free radicals, erroneously associated with aging, are natural and necessary defense mechanisms for the body, and their harmful effects are associated with disruption of natural processes in the body by negative environmental factors and stress.

2. “It’s easy to get poisoned with oxygen.”
Indeed, excess oxygen is dangerous. Excess oxygen causes an increase in the amount of oxidized hemoglobin in the blood and a decrease in the amount of reduced hemoglobin. And, since it is the reduced hemoglobin that removes carbon dioxide, its retention in the tissues leads to hypercapnia - CO2 poisoning.
With an excess of oxygen, the number of free radical metabolites increases, those same terrible “free radicals” that are highly active, acting as oxidizing agents that can damage biological cell membranes.

Terrible, isn't it? I immediately want to stop breathing. Fortunately, in order to become oxygen poisoned, you need increased oxygen pressure, such as in a pressure chamber (during oxygen barotherapy) or when diving with special breathing mixtures. In ordinary life, such situations do not occur.

3. “There is little oxygen in the mountains, but there are many centenarians! Those. oxygen is harmful."
Indeed, in the Soviet Union, a number of centenarians were registered in the mountainous regions of the Caucasus and Transcaucasia. If you look at the list of verified (i.e. confirmed) centenarians of the world throughout its history, the picture will not be so obvious: the oldest centenarians registered in France, the USA and Japan did not live in the mountains..

In Japan, where the oldest woman on the planet, Misao Okawa, who is already more than 116 years old, still lives and lives, there is also the “island of centenarians” Okinawa. The average life expectancy here for men is 88 years, for women - 92; this is higher than the rest of Japan by 10-15 years. The island has collected data on more than seven hundred local centenarians over a hundred years old. They say that: “Unlike the Caucasian highlanders, the Hunzakuts of Northern Pakistan and other peoples who boast of their longevity, all Okinawan births since 1879 have been documented in the Japanese family registry - koseki.” Okinawans themselves believe that the secret to their longevity rests on four pillars: diet, active lifestyle, self-sufficiency and spirituality. Local residents never overeat, adhering to the principle of “hari hachi bu” - to eat eight-tenths full. This “eight-tenths” consists of pork, seaweed and tofu, vegetables, daikon and local bitter cucumber. The oldest Okinawans do not sit idle: they actively work on the land, and their recreation is also active: most of all they love to play the local variety of croquet.: Okinawa is called the happiest island - there is no rush and stress typical of the large islands of Japan. Local residents are committed to the philosophy of yumaru - "a kind-hearted and friendly joint effort."
It is interesting that as soon as Okinawans move to other parts of the country, there are no longer long-livers among such people. Thus, scientists studying this phenomenon have found that the genetic factor does not play a role in the longevity of the islanders. And we, for our part, consider it extremely important that the Okinawa Islands are located in an actively wind-blown zone in the ocean, and the oxygen level in such zones is recorded as the highest - 21.9 - 22% oxygen.

Therefore, the task of the OxyHaus system is not so much to INCREASE the oxygen level in the room, but to RESTORE its natural balance.
In the tissues of the body saturated with a natural level of oxygen, the metabolic process accelerates, the body is “activated,” its resistance to negative factors increases, its endurance and the efficiency of its organs and systems increase.

Technology

Atmung oxygen concentrators utilize NASA-developed PSA (Pressure Swing Absorption) technology. The outside air is purified through a filter system, after which the device releases oxygen using a molecular sieve made from the volcanic mineral zeolite. Pure, almost 100% oxygen is supplied in a flow under pressure of 5-10 liters per minute. This pressure is sufficient to provide a natural level of oxygen in a room up to 30 meters in area.

Air purity

“But the air outside is dirty, and oxygen carries all the substances with it.”
That is why OxyHaus systems have a three-stage incoming air filtration system. And the already purified air enters a zeolite molecular sieve, in which air oxygen is separated.

Danger/safety

“What are the dangers of using the OxyHaus system? After all, oxygen is explosive.”
The concentrator is safe to use. Industrial oxygen cylinders pose a risk of explosion because they contain oxygen under high pressure. The Atmung oxygen concentrators on which the system is based do not contain flammable materials, they use PSA (pressure swing adsorption) technology developed by NASA, it is safe and easy to operate.

Efficiency

“Why do I need your system? I can reduce the CO2 level in a room by opening a window and ventilating it."
Indeed, regular ventilation is a very useful habit and we also recommend it to reduce CO2 levels. However, city air cannot be called truly fresh - in addition to an increased level of harmful substances, it also has a reduced level of oxygen. In the forest, the oxygen content is about 22%, and in city air - 20.5 - 20.8%. This seemingly insignificant difference has a significant impact on the human body.
“I tried to breathe oxygen and didn’t feel anything.”
The effects of oxygen should not be compared with the effects of energy drinks. The positive effects of oxygen have a cumulative effect, so the body's oxygen balance must be replenished regularly. We recommend turning on the OxyHaus system at night and for 3-4 hours a day during physical or intellectual activity. It is not necessary to use the system 24 hours a day.

“What is the difference with air purifiers?”
An air purifier only performs the function of reducing the amount of dust, but does not solve the problem of balancing the oxygen level of stuffiness.
“What is the most favorable oxygen concentration in a room?”
The most favorable oxygen content is close to the same as in a forest or on the seashore: 22%. Even if, due to natural ventilation, your oxygen level is slightly above 21%, this is a favorable atmosphere.

“Is it possible to poison yourself with oxygen?”

Oxygen poisoning, hyperoxia, occurs as a result of breathing oxygen-containing gas mixtures (air, nitrox) at elevated pressure. Oxygen poisoning can occur when using oxygen devices, regenerative devices, when using artificial gas mixtures for breathing, during oxygen recompression, and also due to exceeding therapeutic doses in the process of oxygen barotherapy. With oxygen poisoning, dysfunctions of the central nervous system, respiratory and circulatory system develop.

Oxygen is actively used for breathing. And this is its main function. It is also necessary for other processes that normalize the activity of the entire organism as a whole.

What is oxygen for?

Oxygen is the key to the successful performance of a number of functions, which include:
- increasing mental performance;
- increasing the body's resistance to stress and reducing nervous stress;
- maintaining a normal level of oxygen in the blood, thereby improving the nutrition of skin cells and organs;
- the functioning of internal organs is normalized, metabolism is accelerated;
- increasing immunity;
- weight loss - oxygen promotes active breakdown of fats;
- normalization of sleep - due to the saturation of cells with oxygen, the body relaxes, sleep becomes deeper and lasts longer;
- solving the problem of hypoxia (i.e. lack of oxygen).

Natural oxygen, according to scientists and doctors, is quite capable of coping with these tasks, but, unfortunately, in urban conditions, problems arise with a sufficient amount of oxygen.

Scientists say that the amount of oxygen necessary to ensure normal life can only be found in forested areas, where its level is about 21%, and in suburban forests - about 22%. Other zones include seas and oceans. Plus, exhaust fumes also play a role in the city. Due to the lack of the proper amount of oxygen, people experience a permanent state of hypoxia, i.e. lack of oxygen. As a result, many report a significant deterioration in their health.

Scientists have determined that 200 years ago a person received up to 40% of natural oxygen from the air, and today this figure has decreased by 2 times - to 21%.

How to replace natural oxygen

Since a person clearly does not have enough natural oxygen, doctors recommend adding special oxygen therapy. There are no contraindications for such a procedure, but there will certainly be benefits. Sources of additional oxygen include oxygen cylinders and pillows, concentrators, cocktails, and oxygen-forming cocktails.

In addition, in order to receive the maximum possible amount of natural oxygen, you need to breathe properly. Usually people breastfeed, but this method is incorrect and unnatural for humans. This is due to the fact that when you inhale through the chest, air cannot completely fill the lungs and clear them. Doctors say that chest breathing also provokes improper functioning of the nervous system. Hence stress, depression and other types of disorders. To feel good and get as much oxygen from the air as possible, you need to breathe with your stomach.
