What atmospheric pressure is best for humans. The influence of atmospheric pressure on a person, what atmospheric pressure is considered normal

It is known that Atmosphere pressure during horse racing affects a person’s well-being and health. Every third inhabitant of the Earth is affected by the attraction of air to the surface.

Let's figure out what this concept is and why it negatively affects well-being.

What is atmospheric pressure and how is it measured?

The definition of atmospheric (barometric) pressure is the pressure of air on objects present in it and on the surface. It is measured with barometers or thermohygrometers.

The following units are used:

• bars (1 Ba = 100 thousand Pa);
• Pascals (kPa, hPa, mPa);
• mm mercury(1 mmHg = 133.3 Pa);
• atmosphere (1 at = 98066 Pa);
• kg force per cm 2 (1 kgf/cm 2 = 98066 Pa).

Assuming air temperature remains constant, pressure decreases exponentially as it rises. For altitudes up to approximately 100 km it is calculated by the formula:

p h—pressure at a certain height, Pa;

p 0—surface pressure, Pa;

ρ 0 — density of air masses at zero altitude;

h—height, m;

g is a constant equal to 9.80665;

e - base natural logarithm, a constant equal to 2.71828.

This is interesting: the maximum pressure at sea level was recorded on December 31, 1968 in the village of Agata Krasnoyarsk Territory and reached 812 mm. rt. Art. Lowest value took place on September 24, 1958 in the center of the typhoon near the Philippines and did not exceed 654.8 mm. rt. Art.

Normal atmospheric pressure

Normal pressure is 760 mmHg. Art. At the same time, people feel comfortable or feel good.

The pressure is unstable and fluctuates daily. However, the body is able to calmly withstand a wide range of values. So, in Mexico City average value no more than 570 mm Hg. Art. (due to being at a significant altitude).

The changes are not felt by people. Let’s say that at night the mercury rises by 1-2 units. Jumps of 5-10 or more points can cause painful sensations, and sudden strong fluctuations can even lead to death. For example, loss of consciousness occurs when the pressure drops by 30 points, i.e. at an altitude of 1000 meters.

A continent or a specific country can be divided into zones with different rates of indicator. The optimal value is determined by the area of ​​permanent residence. The human body is capable of adapting to unusual natural conditions.

Banal acclimatization at resorts serves as an example of this. Sometimes a person is unable to change his mind. Thus, those living in the mountains experience poor health in lowland areas, no matter how long they live there.

Thus, the value of the standard pressure is clearly established. And comfortable meaning has a wide range. It is individual and determined by the familiar environment. With prolonged acclimatization, the negative effects are minimized.

High and low atmospheric pressure

Low values ​​cause symptoms similar to those associated with climbing uphill. The lack of oxygen causes shortness of breath, the pulse becomes faster, pain occurs in the temples and pressure on the head.

All this poses a threat to those suffering from hypertension and atherosclerosis, as it causes blood thickening, lack of oxygen and an increase in the number of blood cells. The heart and blood vessels function in an enhanced mode, which contributes to an increase in blood pressure, tachycardia and arrhythmia. Very dangerous for elderly people.

Dizziness and migraines are also common, and the risk of attacks is greater in those suffering from allergies and asthma. Less susceptible, healthy and young people feel the desire to sleep and loss of strength.

In areas of higher values, the weather is calm, there are almost no clouds in the sky, and wind gusts are not strong. The weather is dry and hot.

In zones low pressure a lot of clouds, rainy and windy. Due to such areas, it is cool in the summer with rain, there are a lot of clouds in the sky, and in the winter it snows.

The large difference in the two zones is a factor in causing hurricanes and storms.

Elevated values ​​have a detrimental effect on those suffering from low blood pressure blood, negatively affect digestion, heart and blood vessels.

Atmospheric pressure is normal for humans

People can get used to change. There is no need to be upset if you find out that you live in a region of low pressure. Let’s say that the inhabitants of skyscrapers do not feel a decrease, although a rapid rise of 100 m is very stressful.

In the Central Asian zone, the norm is slightly reduced (715-730 mm Hg). For middle zone RF norm will be 730-770 mmHg. Art.

The body can adapt to different altitudes. According to doctors, if pressure does not have an extremely dangerous effect on people, then this is a variant of the norm. It all depends on adaptation. Doctors often consider values ​​from 750 to 765 mm Hg to be normal. Art.

In Moscow the norm is 747-749 mmHg. Art.

Since Novosibirsk is located at an altitude of 120-130 m, 750 mm Hg is considered the norm. Art.

In Samara - 752-753, in St. Petersburg - 753-755 mm Hg. Art.

The norm in Nizhny Novgorod in the trans-river zone is 754 mm Hg. Art., in Nagornaya - 747.

It is worth noting: there is no overall best indicator. There are territorial norms. People are able to tolerate jumps in values ​​without pain if it goes away gradually.

The healthier the lifestyle and the more often one manages to maintain a daily routine (getting up, sleeping long at night, following a regular diet), the less susceptible a person is to meteorological dependence.

Many suffer from weather changes: what atmospheric pressure is considered normal for a person, and how to avoid feeling unwell, you will learn in this article. At normal atmospheric pressure, an air mass weighing 10,500 kilograms presses on a person! We do not feel this natural load, since oxygen is present in the body in a dissolved state.

Atmospheric pressure standard

Range is 750-760 mmHg. considered normal. Doctors know that many people quickly adapt to any conditions. Even long-distance flights and changes in climate zones do not affect their well-being.

However, most are weather dependent and are sensitive to changes in weather conditions. Severe migraines and weakness, dizziness can occur during surges in atmospheric pressure. Patients often suffer from diseases of the cardiovascular and endocrine systems. A violent reaction to weather changes is due to the fast pace of life, overpopulation of cities and environmental deterioration. Helps you overcome addiction healthy image life:

• running and walking fresh air;
• weight loss;
• eliminating bad habits;
• hardening and swimming;
• balanced diet.

A person’s well-being is usually affected by sudden change atmospheric pressure – more than 1 mm Hg. Art./3 hours. The world standard for measuring blood pressure is pascals. The norm is considered to be 101.3 kPa, which is equal to 760 mmHg.

Natural “barometers” are patients who suffer from pressure changes, allergies, and asthmatics. In addition, changes in weather conditions affect the well-being of people with atherosclerosis, osteochondrosis, rheumatic ailments, and central nervous system diseases. According to statistics, 30% of men and 50% of women in our country suffer from weather “dependence”.

Too high blood pressure leads to a reduction in the pulse rate and a decrease in systole. Breathing becomes deep and rare. Hearing and smell may be slightly reduced, and the voice sounds muffled. There may be a feeling of dry mucous membranes and numbness of the skin.

Low blood pressure is characterized by deep and frequent breathing and a drop in blood pressure. The number of red cells in the blood increases. Due to less oxygen being supplied, it may be difficult to fill the lungs air mass. Getting through a tough day won't be difficult. The less panic and stress, the better. Patients with chronic diseases that worsen during periods of changes in blood pressure should consult a doctor about taking medications.

Normal value is 760 mmHg. happens rarely. Clear weather is characterized by increased readings and an absence of changes in temperature and humidity. Hypertension and allergy sufferers react to such changes.

Patients with breathing problems suffer from windless weather, during which gas pollution in cities increases. The higher the blood pressure, the fewer leukocytes in the blood. Accordingly, the risk of infections increases. Correct mode of the day will help cope with weather changes:

1. Start your morning with gymnastics.
2. Take a contrast shower.
3. Don't overeat.
4. Eat foods containing potassium (banana, dried apricots, cottage cheese).
5. Go to bed no later than 22:00.

You can also take a tincture of hawthorn or motherwort to calm your nerves. Mustard plasters on the calves will help improve the condition.

A decrease in blood pressure is felt by heart patients suffering from intracranial pressure. They may feel a lack of oxygen, have pain in the intestines, and feel general weakness. Reducing mental and physical stress during a weather “crisis” will help normalize your well-being.

Drink throughout the day green tea with honey. To stay in good shape throughout the day, take a tonic cocktail in the form of natural energy drinks. Schisandra, echinacea, ginseng and eleutherococcus, take 30 drops three times a day before meals.

Weather “diseases” are expressed in “wooliness” of the legs, joint pain, and the appearance of swelling. Increased heart rate and decreased blood flow can cause blood clots.

The main complaint on days when weather conditions change is migraine. “Hoop compression” of the head, blurred vision, and nausea prevent you from working productively and generally making any decisions. Periocular cluster pain or concentrated spasms in the area of ​​the nose or eyebrows can unsettle you.

Changes in humidity also affect human health. Low humidity leads to irritation of the nasal mucosa, which is quickly felt by allergy sufferers and asthmatics. To avoid discomfort, additionally moisten the nasopharynx with saline solution. Increasing humidity to 90% leads to exacerbation of joint and kidney ailments.

If you do not feel well in damp conditions, you should minimize the time you spend outside. The warmer you dress, the better you will feel. Vitamins will help overcome high humidity and not catch a cold.

The body recovers during sleep. If the air temperature in the bedroom exceeds +17 degrees, then you will wake up, and rest will not give you vigor. Too cold or hot temperature regime in the sleeping room is harmful. If blood pressure is reduced and air temperature, on the contrary, is increased, then patients with cardiovascular and respiratory diseases do not feel very well.

When blood pressure is elevated and temperature is reduced, asthmatics, hypertensives and people with diseases of the gastrointestinal tract and genitourinary system suffer. Sudden changes in temperature lead to a large number histamine in the body, which provokes allergy attacks. We have no influence on weather changes, but it is possible to help the body. Give up junk food and negative habits, play sports - and it will be much easier to survive weather dependence.

The earth's atmosphere can be compared to a blanket of air that envelops the planet and, with a certain force, presses on everything that is on it. It has been estimated that a person is constantly exposed to air pressure weighing more than ten tons. Yes, yes, it is precisely such a colossal load that does not have any effect on us due to the fact that dissolved in washing tissues human body In liquids, gases balance the load. But here everything is also not so simple, because this pattern is only valid when a person is on a flat surface, and does not dive deep under water or climb mountains.

So, what is atmospheric pressure, and on what conditions does this indicator depend? As already mentioned, this is the force with which a column of air exerts pressure on a certain unit of area. The normal atmospheric pressure is 760 mmHg. in an area located at sea level. However, this value is largely influenced by relief and changes in altitude - the higher above sea level the territory is, the lower the atmospheric pressure there.

The time of day and air temperature also matter: since it is usually colder at night than at daytime, atmospheric pressure indicators are slightly higher. True, the increase in pressure is so small that it does not cause negative changes in well-being. In addition, the values ​​of this indicator fluctuate noticeably at the Earth's poles, while on the equatorial plains they are barely noticeable.

How do changes in atmospheric pressure affect health?

As you know, each person reacts individually to pressure changes and weather changes. Some do not notice any changes at all and are able to travel to different destinations without any problems. climatic zones. And others, and these are the majority, can predict weather changes based on their well-being, without even leaving home. Painful symptoms that appear in response to changes in atmospheric pressure, humidity, and other weather conditions are called weather dependence. This condition is found in approximately four billion people around the globe.

The question is often asked, what atmospheric pressure is considered normal for humans? Taking into account the fact that people are adapted to life in different climatic conditions, in areas located at different altitudes, it is impossible to clearly answer it. For a person, normal atmospheric pressure is one that does not worsen his well-being. This figure ranges from 750 to 765 mmHg.

When there are changes in atmospheric pressure, weather-dependent people experience:

• Headache.
• Vascular spasms.
• Circulatory disorders.
• Increased fatigue and weakness.
• Drowsiness.
• Dizziness.
• Joint pain.
• Numbness of arms and legs.
• Tachycardia.
• Psycho-emotional disorders and irritability.
• Dyspnea.
• Intestinal disorders.
• Nausea.
• Decreased visual acuity and clarity.

Deterioration in well-being is associated with the work of baroreceptors that respond to changes in pressure. In the human body they are located in the pleural and abdominal cavities, joints, blood vessels. Therefore, on the eve of weather changes, such people feel pain in the joints, disturbances in the functioning of the heart, and heaviness in the chest. If a person has digestive problems, he suffers from flatulence and intestinal disorders. Those who have previously suffered a traumatic brain injury or people with aneurysms experience unbearable migraines. With a significant decrease in pressure, the headache is caused by a lack of oxygen in the brain cells.

Emotionally unstable people react very sharply to changes in atmospheric pressure, feeling causeless anxiety, irritability, and sleep disturbances. It is noted that during pressure fluctuations there is large quantity offenses, accidents on highways and high-risk industries.

The influence of atmospheric pressure on arterial pressure person. In hypertensive patients, an increase in atmospheric pressure, during which sunny, clear weather sets in, causes vasoconstriction and spasms, painful headaches, nausea, and hypertensive crises. Also these weather cause a significant decrease in the activity of the immune system.

To the decrease in atmospheric pressure at which there is high humidity, rain, cloudiness, hypotensive people react especially painfully. At this pressure in the air, the concentration of oxygen decreases, and there is an insufficient supply of oxygen to the brain, which causes circulatory disorders. People with low blood pressure suffer from migraines, shortness of breath, tachycardia, lack of air, weakness.

How to become less weather sensitive?

Conducted studies have shown that the development of various health disorders in response to weather changes is based on the following factors:

• Insufficient physical activity.
• Poor nutrition leading to extra pounds gain.
• Instability nervous system caused by constant stress and nervous tension.
• Lack of oxygen and poor ecology.

• Consume foods rich in vitamin B6, magnesium and potassium, vegetables, fruits, lactic acid products, honey.
• Eat less meat, fried and salty foods, sweets, and spices.

It is necessary to limit the consumption of alcoholic beverages and stop smoking. You should make it a rule to do exercises every day, take walks in the fresh air, and sleep at least seven to eight hours. It is also useful to use natural adaptogens, such as tinctures of Eleutherococcus, ginseng, and preparations based on antlers. reindeer. But, since these drugs have some contraindications and may have side effects, you should consult your doctor about the advisability of taking them.

If the weather changes, patients with hypertension also feel unwell. Let's consider how atmospheric pressure affects hypertensive and weather-sensitive people.

Weather dependent and healthy people

Healthy people do not feel any changes in the weather. People who are weather dependent experience the following symptoms:

• Dizziness;
• Drowsiness;
• Apathy, lethargy;
• Joint pain;
• Anxiety, fear;
• Gastrointestinal dysfunction;
• Fluctuations in blood pressure.

Often, health worsens in the fall, when there is an exacerbation of colds and chronic diseases. In the absence of any pathologies, meteosensitivity manifests itself as malaise.

Unlike healthy people, weather-dependent people react not only to fluctuations in atmospheric pressure, but also to increased humidity, sudden cold or warming. The reasons for this are often:

• Low physical activity;
• Presence of diseases;
• Decline of immunity;
• Deterioration of the central nervous system;
• Weak blood vessels;
• Age;
• Ecological situation;
• Climate.

As a result, the body's ability to quickly adapt to changes in weather conditions deteriorates.

If the atmospheric pressure is high (above 760 mm Hg), there is no wind and precipitation, they speak of the onset of an anticyclone. There are no sudden temperature changes during this period. The amount of harmful impurities in the air increases.

Anticyclone has a negative effect on hypertensive patients. An increase in atmospheric pressure leads to an increase in blood pressure. Performance decreases, pulsation and pain in the head, and heart pain appear. Other symptoms of the negative influence of the anticyclone:

• Increased heart rate;
• Weakness;
• Noise in ears;
• Facial redness;
• Flashing "flies" before the eyes.

The number of white blood cells in the blood decreases, which increases the risk of developing infections.

Elderly people with chronic cardiovascular diseases are especially susceptible to the effects of the anticyclone.. With an increase in atmospheric pressure, the likelihood of a complication of hypertension - a crisis - increases, especially if the blood pressure rises to 220/120 mm Hg. Art. Other dangerous complications may develop (embolism, thrombosis, coma).

Low atmospheric pressure also has a bad effect on patients with hypertension - a cyclone. It is characterized cloudy weather, precipitation, high humidity. Air pressure drops below 750 mm Hg. Art. The cyclone has the following effect on the body: breathing becomes more frequent, the pulse quickens, however, the force of the heart beat is reduced. Some people experience shortness of breath.

When air pressure is low, blood pressure also drops. Considering that hypertensive patients take medications to lower blood pressure, the cyclone has a bad effect on their well-being. The following symptoms appear:

• Dizziness;
• Drowsiness;
• Headache;
• Prostration.

In some cases, there is a deterioration in the functioning of the gastrointestinal tract.

When atmospheric pressure increases, patients with hypertension and weather-sensitive people should avoid active physical activity. We need to rest more. A low-calorie diet containing increased amount fruit.

Even “advanced” hypertension can be cured at home, without surgery or hospitals. Just remember once a day...

If the anticyclone is accompanied by heat, it is also necessary to avoid physical activity. If possible, you should be in an air-conditioned room. A low-calorie diet will be relevant. Increase the amount of potassium-rich foods in your diet.

To normalize blood pressure at low atmospheric pressure, doctors recommend increasing the volume of fluid consumed. Drink water, infusions medicinal herbs. Need to reduce physical activity, rest more.

Sound sleep helps a lot. In the morning, you can have a cup of caffeinated drink. During the day you need to measure your blood pressure several times.

Effect of pressure and temperature changes

Changes in air temperature can also cause many health problems for hypertensive patients. During the period of an anticyclone, combined with heat, the risk of cerebral hemorrhages and heart damage increases significantly.

Due to high temperature and high humidity the oxygen content in the air decreases. This weather has a particularly bad effect on older people.

The dependence of blood pressure on atmospheric pressure is not so strong when heat is combined with low humidity and normal or slightly increased air pressure.

However, in some cases, such weather conditions cause blood thickening. This increases the risk of blood clots and the development of heart attacks and strokes.

The well-being of hypertensive patients will worsen if the atmospheric pressure rises simultaneously with a sharp drop in temperature environment. With high humidity, strong wind hypothermia (hypothermia) develops. Excitation of the sympathetic nervous system causes a decrease in heat transfer and an increase in heat production.

The reduction in heat transfer is caused by a decrease in body temperature due to vasospasm. The process helps to increase the body's thermal resistance. To protect the extremities and facial skin from hypothermia, the blood vessels located in these parts of the body narrow.

If the cooling of the body is very sharp, persistent vascular spasm develops. This may cause an increase in blood pressure. In addition, a sharp cold snap changes the composition of the blood, in particular, the number of protective proteins is reduced.

Above sea level

As you know, the higher you are from sea level, the lower the air density and the lower the atmospheric pressure. At an altitude of 5 km it decreases by about 2 r. The influence of air pressure on the blood pressure of a person located high above sea level (for example, in the mountains) is manifested by the following symptoms:

• Increased breathing;
• Heart rate acceleration;
• Headache;
• Attack of suffocation;
• Nosebleeds.

At the core negative impact Low air pressure causes oxygen starvation, when the body receives less oxygen. Subsequently, adaptation occurs, and health becomes normal.

A person who permanently lives in such an area does not feel the effects of low atmospheric pressure. You should know that in hypertensive patients, when rising to altitude (for example, during flights), blood pressure may change sharply, which threatens loss of consciousness.

Underground

Underground and water air pressure is increased. Its effect on blood pressure is directly proportional to the distance to which it must be descended.

The following symptoms appear: breathing becomes deep and rare, heart rate decreases, but only slightly. The skin becomes slightly numb, the mucous membranes become dry.

The body is hypertensive, like ordinary person, adapts better to changes in atmospheric pressure if they occur slowly.

Much more severe symptoms develop due to a sharp change: increase (compression) and decrease (decompression). In conditions high blood pressure miners and divers work in the atmosphere.

They descend and rise underground (underwater) through sluices, where the pressure increases/decreases gradually. At increased atmospheric pressure, gases contained in the air dissolve in the blood. This process is called "saturation". During decompression, they leave the blood (desaturation).

If a person descends to a great depth underground or under water in violation of the venting regime, the body will become oversaturated with nitrogen. Caisson disease will develop, in which gas bubbles penetrate into the vessels, causing multiple embolisms.

The first symptoms of the pathology of the disease are muscle and joint pain. In severe cases, the eardrums burst, dizziness occurs, and labyrinthine nystagmus develops. Caisson disease is sometimes fatal.

Meteopathy

Meteopathy is the body's negative reaction to weather changes. Symptoms range from mild malaise to severe myocardial dysfunction, which can cause irreversible tissue damage.

The intensity and duration of manifestations of meteoropathy depend on age, body composition, and the presence of chronic diseases. For some, the ailments continue for up to 7 days. According to medical statistics Meteopathy occurs in 70% of people with chronic illnesses and 20% of healthy people.

The reaction to weather changes depends on the degree of sensitivity of the body. The first (initial) stage (or meteosensitivity) is characterized by a slight deterioration in well-being, which is not confirmed by clinical studies.

The second degree is called meteodependence, it is accompanied by changes in blood pressure and heart rate. Meteopathy is the most severe third degree.

With hypertension combined with weather dependence, the cause of deterioration in well-being can be not only fluctuations in atmospheric pressure, but also other environmental changes. Such patients need to pay attention to weather conditions and weather forecasts. This will allow you to take the measures recommended by your doctor in a timely manner.

We are taught about what atmospheric pressure is at school during natural history and geography lessons. We get acquainted with this information and safely throw it out of our heads, rightly believing that we will never be able to use it.

But over the years, stress and environmental conditions will have a sufficient impact on us. And the concept of “geodependence” will no longer seem nonsense, because pressure surges and headaches will begin to poison life. At this moment you will have to remember what it is like in Moscow, for example, in order to adapt to new conditions. And move on with your life.

School basics

The atmosphere that surrounds our planet, unfortunately, literally puts pressure on all living and nonliving things. There is a term to define this phenomenon - atmospheric pressure. This is the force of the air column acting on the area. In the SI system we talk about kilograms per square centimeter. Normal atmospheric pressure (optimal indicators for Moscow have long been known) affects the human body with the same force as a weight weighing 1.033 kg. But most of us don't notice this. There are enough gases dissolved in body fluids to neutralize all unpleasant sensations.

Atmospheric pressure standards in different regions are different. But 760 mmHg is considered ideal. Art. Experiments with mercury turned out to be the most revealing at a time when scientists were proving that air has weight. Mercury barometers are the most common devices for determining pressure. It should also be remembered that the ideal conditions for which the mentioned 760 mm Hg are relevant. Art., is a temperature of 0 ° C and the 45th parallel.

IN international system units are used to define pressure in Pascals. But for us, the use of mercury column fluctuations is more familiar and understandable.

Relief features

Of course, many factors influence the value of atmospheric pressure. The most significant are the relief and proximity to magnetic poles planets. The norm of atmospheric pressure in Moscow is fundamentally different from the indicators in St. Petersburg; and for residents of some remote village in the mountains, this figure may seem completely abnormal. Already at 1 km above sea level it corresponds to 734 mm Hg. Art.

As already noted, in the region of the Earth’s poles the amplitude of pressure changes is much higher than in equatorial zone. Even during the day, the atmospheric pressure changes slightly. Insignificantly, however, only by 1-2 mm. This is due to the difference between day and night temperatures. At night it is usually cooler, which means the pressure is higher.

Pressure and man

For a person, in essence, it does not matter what atmospheric pressure is: normal, low or high. These are very conditional definitions. People tend to get used to everything and adapt. The dynamics and magnitude of changes in atmospheric pressure are much more important. On the territory of the CIS countries, in particular in Russia, there are quite a lot of zones. Often local residents and don't know about it.

The norm of atmospheric pressure in Moscow, for example, may well be considered as a variable value. After all, every skyscraper is a kind of mountain, and the higher and faster you go up (or go down), the more noticeable the difference will be. Some people may well pass out while riding a high-speed elevator.

Adaptation

Doctors almost unanimously agree that the question “what atmospheric pressure is considered normal” (is it Moscow or any locality planets - not the point) is incorrect in itself. Our body adapts perfectly to life above or below sea level. And if the pressure does not have a detrimental effect on a person, it can be considered normal for the area. Doctors say that the standard atmospheric pressure in Moscow and other major cities is in the range from 750 to 765 mmHg. pillar

The pressure drop is a completely different matter. If within a few hours it rises (falls) by 5-6 mm, people begin to experience discomfort and pain. This is especially dangerous for the heart. Its beating becomes more frequent, and a change in the frequency of breaths leads to a change in the rhythm of oxygen supply to the body. The most common ailments in such a situation are weakness, etc.

Meteor dependence

Normal atmospheric pressure for Moscow may seem like a nightmare to a visitor from the North or the Urals. After all, each region has its own norm and, accordingly, its own understanding of the stable state of the body. And since in life we ​​do not concentrate on exact pressure indicators, weather forecasters always focus on whether the pressure is high or low for a given region.

After all, not every person can boast that they do not notice the corresponding changes. Anyone who cannot call himself lucky in this matter must systematize his feelings during pressure changes and find acceptable countermeasures. Often a cup of strong coffee or tea is enough, but sometimes more serious help in the form of medication is needed.

Pressure in the metropolis

Residents of megacities are the most weather-dependent. It is here that a person experiences more stress, lives life at a high pace and experiences environmental degradation. Therefore, knowing what the normal atmospheric pressure is for Moscow is vital.

The capital of the Russian Federation is located on Central Russian Upland, which means that there is a priori a zone of low pressure here. Why? It's very simple: the higher you are above sea level, the lower the atmospheric pressure. For example, on the banks of the Moscow River this figure will be 168 m. And the maximum value in the city was recorded in Teply Stan - 255 m above sea level.

It is quite possible to assume that Muscovites will experience abnormally low atmospheric pressure much less frequently than residents of other regions, which, of course, cannot but make them happy. And yet, what atmospheric pressure is considered normal in Moscow? Meteorologists say that it usually does not exceed 748 mm Hg. pillar This means little, since we already know that even a quick ride in an elevator can have a significant impact on a person's heart.

On the other hand, Muscovites do not feel any discomfort if the pressure fluctuates between 745-755 mm Hg. Art.

Danger

But from the point of view of doctors, not everything is so optimistic for the residents of the metropolis. Many experts quite reasonably believe that by working on the upper floors of business centers, people expose themselves to danger. Indeed, in addition to the fact that they live in a zone of low pressure, they also spend almost a third of the day in places with

If we add to this fact violations of the building ventilation system and permanent job air conditioners, it becomes obvious that the employees of such offices are the most incapacitated, sleepy and sick.

Results

Actually, there are a few things to remember. Firstly, there is no single ideal value for normal atmospheric pressure. There are regional standards that can vary significantly in absolute terms. Secondly, the characteristics of the human body make it easy to experience pressure changes if they happen rather slowly. Thirdly, the healthier lifestyle we lead and the more often we manage to maintain a daily routine (getting up at the same time, long night sleep, following a basic diet, etc.), the less we are susceptible to weather dependence. This means they are more energetic and cheerful.
