Normal atmospheric pressure for humans - what do the indicators depend on? Normal atmospheric pressure.
Atmospheric pressure is the force with which a column of air presses on a certain unit area of the Earth. It is often measured in kilograms per square meter, and from there they are transferred to other units. Atmospheric pressure varies around the globe, depending on geographical location. Normal, habitual blood pressure is extremely important for the human body to function properly. You need to understand what atmospheric pressure is normal for a person, and how its changes can affect well-being.
When rising to a height the indicator atmospheric pressure decreases; when going down, it increases. Also, this indicator may depend on the time of year and humidity in a particular area. In everyday life it is measured using a barometer. It is customary to indicate atmospheric pressure in millimeters mercury.
The ideal atmospheric pressure is considered to be 760 mmHg, but in Russia and most of the planet in general, this figure is far from this ideal.
The normal force of air pressure is considered to be that at which a person feels comfortable. Moreover, for people from different places habitats in which normal well-being is maintained will be different. A person usually gets used to the indicators of the area in which he lives. If a resident of the highlands moves to the lowlands, he will experience discomfort for some time and gradually get used to the new conditions.
However, even at permanent place residence, the atmospheric pressure may change. This usually happens with changing seasons and sudden changes in weather. In this case, people with a number of pathologies and congenital weather dependence may experience discomfort, and old diseases may begin to worsen.
It is worth knowing how you can improve your condition if there is a sharp drop or increase in atmospheric pressure. You don’t have to immediately run to the doctor - there are home techniques that have been tested by many people that can help you start feeling better.
Important! It is worth noting that people sensitive to change weather conditions, you should be more careful when choosing places to spend your vacation or move.
What indicator is considered normal for a person?
Many experts say: normal blood pressure for a person will be 750–765 mmHg. It is easiest to adapt to indicators within these limits. For most people living on plains, small hills, and lowlands, they will be suitable.
It is worth noting that the most dangerous thing is not increased or decreased indicators, but their sudden change. If changes happen gradually, most people won't notice them. Abrupt change can lead to negative consequences: Some people may faint during a sharp climb uphill.
Pressure norm table
IN different cities countries, the indicators will be different - this is the norm. Usually detailed weather reports tell you whether the atmospheric pressure is above or below normal. this moment time. You can always calculate the norm for your place of residence yourself, but it is easier to refer to ready-made tables. For example, here are the indicators for several cities in Russia:
City name | Normal atmospheric pressure (in millimeters of mercury) |
Moscow | 747–748 |
Rostov on Don | 740–741 |
Saint Petersburg | 753–755, in some places – up to 760 |
Samara | 752–753 |
Ekaterinburg | 735–741 |
Permian | 744–745 |
Tyumen | 770–771 |
Chelyabinsk | 737–744 |
Izhevsk | 746–747 |
Yaroslavl | 750–752 |
It is worth noting that for some cities and regions large pressure drops are normal. Local residents are usually well adapted to them, bad feeling will arise only for a visitor.
Important! If weather dependence occurs suddenly and has never been observed before, you should consult a doctor - this may indicate heart disease.
Effect on the body
For people with certain medical conditions and increased sensitivity to weather changes, pressure changes can negatively affect them, in some cases limiting their ability to work. Experts note: women are slightly more likely than men to react to weather changes.
People have different reactions to changes. Some people feel a slight discomfort that easily goes away on their own after some time. Others require special medications to avoid exacerbation of any disease that may occur due to changing weather conditions.
The following groups of people are most prone to negative experiences during pressure changes:
- WITH various diseases lungs, which include bronchial asthma, obstructive and chronic bronchitis.
- With heart and vascular diseases, especially hypertension, hypotension, atherosclerosis, and other disorders.
- With brain diseases, rheumatic pathologies, diseases of the musculoskeletal system, especially osteochondrosis.
It is also believed that changes in weather conditions provoke allergy attacks. In completely healthy people, the changes usually do not have a pronounced effect.
People with weather dependence experience headaches, drowsiness, fatigue, and pulse irregularities that are not observed with normal conditions. In this case, it is advised to consult a doctor to exclude the development of heart disease and nervous system.
In addition to headaches and fatigue, people with various diseases may experience discomfort in the joints, changes in blood pressure, numbness in the lower extremities, and muscle pain. In case of exacerbation of chronic diseases, you should take medications prescribed by your doctor.
What to do if you are weather dependent
If increased sensitivity to changing weather conditions is present, but there are no diseases leading to it, then the following recommendations will help you cope with unpleasant sensations.
In the morning it is advised to take cold and hot shower, then drink a cup good coffee to keep yourself in good shape. It is recommended to drink more tea during the day. Better - green with lemon. It will be useful to do exercises, several times a day.
Towards evening it is advised to relax. Herbal teas and decoctions with honey, valerian infusion and other mild sedatives will help with this. It is recommended to go to bed early and eat less salty foods during the day.
Pressure is a physical quantity that shows the acting force per unit area of a surface perpendicular to this surface.
Pressure is defined as P = F / S, where P is pressure, F is pressure force, S is surface area. From this formula it is clear that pressure depends on the surface area of the body acting with a certain force. How smaller area surface, the greater the pressure.
The unit of pressure is newton per square meter (N/m2).
We can also convert pressure units N/m 2 to pascals, units named after the French scientist Blaise Pascal, who developed the so-called Pascal's Law. 1 N/m 2 = 1 Pa.

Atmospheric pressure - barometer.
And so, once again the pressure is defined as P = F / S. The force in the gravitational field is equal to the weight - F = m * g, where m is the mass of the body; g is the acceleration of free fall. Then the pressure is
P = m * g / S . Using this formula, you can determine the pressure exerted by the body on the surface.
enter through a dot. Atmospheric pressure decreases with altitude. The dependence of atmospheric pressure on altitude is determined -
barometric formula
P = Po*exp(- μgh/RT) . Where, μ = 0.029 kg/m3 - molecular weight of gas (air); g = 9.81 m/s2 - free fall acceleration;
h - h o - difference in altitude above sea level and the accepted altitude at the beginning of the report (h=h o); R = 8.31 - J/mol K - gas constant;
Po - atmospheric pressure at the height taken as the reference point;

If you have chronic headaches, chest pain, a systematic increase in blood pressure, a general deterioration in health due to changes in atmospheric pressure, we recommend that you read our article, take care of your health! In each region of Russia, different atmospheric pressure is considered normal. Therefore, in weather reports, when the number of millimeters of mercury is announced, weather forecasters always say what pressure it is for this area, above or below normal. In addition to atmospheric pressure, many factors influence our well-being. What to do if you have breathing problems? Take care of your health, this is the only thing that no amount of money can buy!
You can find out how air density depends on temperature, it’s very interesting! high point in the city itself it is located in the Teply Stan area - it is 255 meters.
Meteorologists call specific figure normal atmospheric pressure for Moscow is 747-748 mm Hg. pillar This is of course how average temperature around the hospital. People who permanently live in Moscow feel normal in the range 745-755 mm Hg pillar The main thing is that the pressure drops are not serious.
Doctors believe that, for example, working on the upper floors is dangerous for residents of the metropolis. If the building's airtightness and ventilation system is broken in a high-rise building, then employees of such offices may feel constant headache and performance problems. It's all about pressure that is abnormal for them.
Normal atmospheric pressure in St. Petersburg ^
For St. Petersburg residents the situation is different. Due to the fact that St. Petersburg is lower above sea level than Moscow, higher pressure is the norm. Average, normal atmospheric pressure for St. Petersburg is 753-755 mm Hg. pillar However, in some sources you can see another figure - 760 mm Hg. pillar However, it is only valid for low-lying areas of St. Petersburg.
Due to its location Leningrad region has unstable climate indicators, and atmospheric pressure can fluctuate significantly. For example, it is not uncommon for it to rise to 780 mmHg during an anticyclone. pillar And in 1907, a record atmospheric pressure was recorded - 798 mm Hg. pillar This is 30 mm more than normal.
Do you need a Chizhevsky lamp for your home? You will find the answer to this question at the following address. Let's take care of our health!
What is the value of normal atmospheric pressure in pascals? ^
We are used to measuring atmospheric pressure in millimeters of mercury. However, the international system defines pressure in pascals. So, standard atmospheric pressure, according to IUPAC requirements, is 100 kPa.
Let's convert our measurement of mercury barometers into pascals. So, 760 mmHg column is 1013.25 mb. According to the SI system, 1013.25 mb is equal to 101.3 kPa.
But still, measuring pressure in Russia in pascals is rare. Same as standard 760 mmHg. pillar An ordinary resident of Russia just needs to remember what pressure is normal for his region.
Let's summarize.
- Normal atmospheric pressure is 760 mm Hg. pillar However, it is rarely found anywhere. A person is quite comfortable living in the range from 750 to 765 mmHg. pillar
- In each region of the country, different pressures are considered normal for that region. If a person lives in the zone low pressure, he gets used to it and adapts to it.
- Normal atmospheric pressure for Moscow is 747-748 mm Hg. pillar, for St. Petersburg - 753-755 mm.
- The normal pressure value in pascals will be 101.3 kPa.
If you want to measure the atmospheric pressure in your region and find out how much it corresponds to the norm, we recommend using the most modern device- electronic barometer. If you are weather dependent and suffer from sudden changes in atmospheric pressure, it is recommended to use a tonometer to check the quality of your own health.

Atmospheric air has a physical density, as a result of which it is attracted to the Earth and creates pressure. During the development of the planet, both the composition of the atmosphere and its atmospheric pressure changed. Living organisms were forced to adapt to the existing air pressure, changing their physiological characteristics. Deviations from average atmospheric pressure cause changes in a person’s well-being, and the degree of sensitivity of people to such changes varies.
Normal atmospheric pressure
The air extends from the Earth's surface to heights of the order of hundreds of kilometers, beyond which interplanetary space begins, while the closer to the Earth, the more compressed the air is under the influence of own weight, accordingly, the atmospheric pressure is highest at earth's surface, decreasing with increasing altitude.
At sea level (from which all altitudes are usually measured), at a temperature of +15 degrees Celsius, the atmospheric pressure averages 760 millimeters of mercury (mmHg). This pressure is considered normal (with physical point vision), which does not mean that this pressure is comfortable for a person under any conditions.
Atmospheric pressure is measured by a barometer, graduated in millimeters of mercury (mmHg), or in other physical units, such as pascals (Pa). 760 millimeters of mercury corresponds to 101,325 pascals, but in everyday life the measurement of atmospheric pressure in pascals or derived units (hectopascals) has not taken root.
Previously, atmospheric pressure was also measured in millibars, which fell out of use and were replaced by hectopascals. Normal atmospheric pressure is 760 mm Hg. Art. corresponds to the standard atmospheric pressure of 1013 mbar.
Pressure 760 mm Hg. Art. corresponds to the action of a force of 1.033 kilograms on each square centimeter of the human body. In total, air presses on the entire surface of the human body with a force of about 15-20 tons.
But a person does not feel this pressure, since it is balanced by air gases dissolved in tissue fluids. This balance is disrupted by changes in atmospheric pressure, which a person perceives as a deterioration in well-being.
For some areas, the average atmospheric pressure differs from 760 mm. Hg Art. So, if in Moscow the average pressure is 760 mm Hg. Art., then in St. Petersburg it is only 748 mm Hg. Art.
At night, the atmospheric pressure is slightly higher than during the day, and at the Earth's poles, atmospheric pressure fluctuations are more pronounced than at equatorial zone, which only confirms the pattern that the polar regions (Arctic and Antarctic) as habitats are hostile to humans.
In physics, the so-called barometric formula is derived, according to which, with an increase in altitude for every kilometer, atmospheric pressure drops by 13%. The actual distribution of air pressure does not follow the barometric formula quite accurately, since temperature, atmospheric composition, water vapor concentration and other indicators change depending on the altitude.
Atmospheric pressure also depends on the weather, when air masses move from one area to another. All living things on Earth also respond to atmospheric pressure. Thus, fishermen know that the standard atmospheric pressure for fishing is reduced, because when the pressure drops predatory fish prefers to go hunting.
Weather-dependent people, and there are 4 billion of them on the planet, are sensitive to changes in atmospheric pressure, and some of them can quite accurately predict weather changes, guided by their well-being.
It is quite difficult to answer the question of what standard of atmospheric pressure is most optimal for places of residence and human life, since people adapt to life in different climatic conditions. Typically the pressure is between 750 and 765 mmHg. Art. does not worsen a person’s well-being; these atmospheric pressure values can be considered within the normal range.
When atmospheric pressure changes, weather-dependent people may feel:
- headache;
- vascular spasms with circulatory disorders;
- weakness and drowsiness with increased fatigue;
- joint pain;
- dizziness;
- feeling of numbness in the limbs;
- decreased heart rate;
- nausea and intestinal disorders;
- shortness of breath;
- decreased visual acuity.
The first thing to react to changes in pressure are those located in the cavities of the body, joints and blood vessels baroreceptors.
When pressure changes, weather-sensitive people experience disturbances in the functioning of the heart, heaviness in the chest, pain in the joints, and in case of digestive problems, also flatulence and intestinal disorders. With a significant decrease in pressure, a lack of oxygen in brain cells leads to headaches.
Also, changes in pressure can lead to disturbances mental state- people feel anxious, irritated, sleep restlessly, or generally cannot sleep.
Statistics confirm that with sudden changes in atmospheric pressure, the number of crimes, accidents in transport and production increases. The influence of atmospheric pressure on arterial pressure is traced. In hypertensive patients, increased atmospheric pressure can cause a hypertensive crisis with headache and nausea, despite the fact that at this moment clear sunny weather sets in.
On the contrary, hypotensive patients react more sharply to a decrease in atmospheric pressure. The reduced concentration of oxygen in the atmosphere causes circulatory disorders, migraines, shortness of breath, tachycardia and weakness.
Weather sensitivity can be a consequence of an unhealthy lifestyle. The following factors can lead to weather sensitivity or aggravate its severity:
- low physical activity;
- poor nutrition with accompanying excess weight;
- stress and constant nervous tension;
- poor state of the external environment.
Elimination of these factors reduces the degree of meteosensitivity. Weather-sensitive people should:
- include foods high in vitamin B6, magnesium and potassium in your diet (vegetables and fruits, honey, lactic acid products);
- limit the consumption of meat, salty and fried foods, sweets and spices;
- stop smoking and drinking alcohol;
- increase physical activity, do walking in the fresh air;
- organize your sleep, sleep at least 7-8 hours.

Many people are subject to change in environment. A third of the population is affected by gravity air masses to the ground. Atmospheric pressure: the norm for humans, and how deviations from the indicators affect the general well-being of people.
Changes in the weather can affect a person's condition
What atmospheric pressure is considered normal for humans?
Atmospheric pressure is the weight of air that presses on the human body. On average, this is 1.033 kg per 1 cubic cm. That is, 10-15 tons of gas control our mass every minute.
Its generally accepted norm is 760 mmHg or 1013.25 mbar. Conditions in which the human body feels comfortable or adapted. In fact, an ideal weather indicator for any inhabitant of the Earth. In reality, everything is not like that.
Atmospheric pressure is not stable. Its changes are daily and depend on the weather, terrain, sea level, climate and even time of day. The vibrations are not noticeable to humans. For example, at night the mercury rises 1-2 notches higher. Minor changes do not affect well-being healthy person. Changes of 5-10 or more units are painful, and sudden significant jumps are fatal. For comparison: loss of consciousness from altitude sickness occurs when pressure drops by 30 units. That is, at a level of 1000 m above the sea.
continent and even separate country can be divided into conditional areas with different norm medium pressure. Therefore, the optimal atmospheric pressure for each person is determined by the region of permanent residence.
An example of the distribution of atmospheric pressure over Russia in January
Flexible human body has the potential to adapt to strangers natural conditions. The notorious resort acclimatization is an example of this. It happens when restructuring is impossible. So the inhabitants of the mountains suffer from poor health in the lowlands, no matter how long they stay there.
Doctors confirm the theory that the appropriate level of pressure is measured not by numbers, but by individual well-being. And yet the optimal value for the average person is within 750-765 mm.
Atmospheric pressure standards in different regions
Each region of Russia has developed an individual level of pressure. In Moscow, ideal 760 mm practically does not exist. The average value is 747-749 units. For Muscovites, the increase to 755 mm is not noticeable. The values above sometimes affect your well-being. Moscow is located on a hill, so pressure above average is a priori impossible. In the Moscow region, the divisions are even lower: the territory is located above the capital.
Table “Normal atmospheric pressure for Russian cities”
In Donetsk, the atmospheric pressure also differs from the region. In the city the average is 744-745 mm, and populated areas closer to sea level – 749-750.
What effect does atmospheric pressure have on humans?
Atmospheric and blood pressure are interrelated. A decrease in mbar (cloudy, rainy weather) affects the body:
- lowering blood pressure;
- drowsiness and apathy;
- decreased heart rate;
- difficulty breathing;
- rapid fatigue;
- dizziness and pain;
- nausea;
- problems with the gastrointestinal tract;
- migraine.
During rainy weather feeling drowsy
People with depressed respiratory functions are also at risk for hypotension. Their health on such days is characterized by aggravated symptoms and attacks. Cases of hypotensive crisis are becoming more frequent.
Increased air pressure (clear, dry, windless and warm weather) brings a depressed state of health to hypertensive patients. The symptoms are opposite:
- increased blood pressure;
- increased heart rate;
- facial redness;
- headache;
- noise in ears;
- dizziness;
- pulsation in temples;
- “flies” before the eyes;
- nausea.
High pressure air has a negative effect on hypertensive patients
Such weather conditions are generous for strokes and heart attacks.
For people who are vulnerable to the vagaries of nature, doctors advise staying out of the area on such days. active work and combat the consequences of weather dependence.
Meteor dependence - what to do?
The movement of mercury by more than one division in 3 hours is a reason for stress in the strong body of a healthy person. Each of us feels such fluctuations in the form of headaches, drowsiness, and fatigue. More than a third of people suffer from weather dependence in varying degrees gravity. In the zone of high sensitivity, populations with diseases of the cardiovascular, nervous and respiratory system, aged people. How to help yourself if a dangerous cyclone is approaching?
15 ways to survive a weather cyclone
There's not a lot of new advice here. Together they are believed to alleviate suffering and teach the right image life with weather vulnerability:
- See your doctor regularly. Consult, discuss, ask for advice in case your health worsens. Always have prescribed medications on hand.
- Buy a barometer. It is more productive to track the weather by the movement of the mercury column, rather than by knee pain. This way you will be able to anticipate the approaching cyclone.
- Keep an eye on the weather forecast. Forewarned is forearmed.
- On the eve of a weather change, get enough sleep and go to bed earlier than usual.
- Adjust your sleep schedule. Provide yourself with a full 8 hours of sleep, getting up and falling asleep at the same time. This has a powerful restorative effect.
- Meal schedule is equally important. Maintain a balanced diet. Potassium, magnesium and calcium are essential minerals. Ban on overeating.
- Take vitamins in a course in spring and autumn.
- Fresh air, walks outside - light and regular exercise strengthens the heart.
- Don't overexert yourself. Putting off household chores is not as dangerous as weakening the body before a cyclone.
- Accumulate favorable emotions. Depressed emotional background fuels the disease, so smile more often.
- Clothes made from synthetic threads and fur are harmful due to static current.
- Store traditional methods symptoms relief list in a visible place. Recipe herbal tea or a compress is difficult to remember when your temples ache.
- Office workers in high-rise buildings suffer more often from weather changes. Take time off if possible, or better yet, change jobs.
- A long cyclone means discomfort for several days. Is it possible to go to a quiet region? Forward.
- Prevention at least a day before the cyclone prepares and strengthens the body. Do not give up!
Don't forget to take vitamins to improve your health
Atmosphere pressure
- This is a phenomenon that is absolutely independent of man. Moreover, our body obeys it. Which should be optimal pressure for a person determines the region of residence. People with chronic diseases are especially susceptible to weather dependence.
Weather-dependent people are more often than others interested in what atmospheric pressure is considered normal for a person. The weight of the air mass is so great that the human body can withstand a load of over 15 tons. Compensation through pressure helps you not to feel such a load. internal organs. When, due to problems in the body, the adaptation system cannot cope, a weather-dependent person becomes a slave to the weather disaster. The intensity of symptoms depends on how low or high your blood pressure is.
What does the barometer say?
It is known that the pressure force air envelope Earth per 1 cm² of surface, balanced by a column of mercury 760 mm high. This indicator is accepted as the norm. When the barometer gives a result higher than 760 mmHg, they speak of increased atmospheric pressure when it is less than 760 mmHg. Art. - about the reduced one. Considering the fact that the Earth's surface heats up unevenly and the terrain is heterogeneous (mountains, lowlands), the barometer readings will differ.

Favorable weather
Every person is unique. The norm of atmospheric pressure for it will also be unique. Some people will not notice the flight to another climate zone, while others will feel the approach of a cyclone, which will manifest itself as a headache and “twisting” of the knees. Others have climbed higher into the mountains and feel great, not paying attention to the thin air. A set of natural and weather conditions under which one can feel comfortable and have normal atmospheric pressure for a person. The older a person gets, the more strongly he feels climate change.

What is weather dependence?
Weather dependence is the inability of the human body to adapt to changing weather conditions.
People suffering from vegetative-vascular dystonia are more prone to weather dependence. hypertension, atherosclerosis, endocrine diseases. The baroreceptors of our organs react to the approach of a cyclone or anticyclone, reducing or increasing blood pressure, making them dependent on weather conditions.

The effect of high atmospheric pressure on blood pressure
The body has the ability to equalize atmospheric pressure with arterial pressure.
An increase in atmospheric pressure forces blood pressure to equalize the imbalance. Arterial pressure decreases, the walls of blood vessels expand. Consequences of hypotension:
- concerned about poor health and general weakness;
- suffer from headaches;
- there is an unpleasant “fullness” in the ears;
- Chronic diseases are getting worse.
Blood chemistry under these conditions will show a decrease in white blood cell levels, which means that immune system it will be more difficult to cope with the infection or virus. The best decision in such situation:
- do not overexert yourself and have a good rest;
- limit alcohol intake during this time;
- enrich the diet with foods containing potassium (dried fruits) and magnesium (cereals, rye bread).

The effect of low atmospheric pressure on humans
A drop in atmospheric pressure when the weather changes leads to symptoms that are similar to mountain climbing. An insufficient amount of oxygen is unable to saturate the organs of the human body. Shortness of breath appears, the heart beats faster, pain presses in the temples and squeezes the head like a hoop. People with increased intracranial pressure, head injuries, and cardiovascular diseases react sharply to this.

How to deal with weather dependence?
- nutrition - limit the consumption of fatty, salty foods, focus on dairy products, fruits and vegetables;
- work - balance periods of rest and intensive work, take breaks more often;
- sleep - it should be sufficient, not exceed 7-8 hours, good decision- do not go to bed later than 11 pm;
- physical activity - regular, moderately intense (daily morning exercises, jogging in the summer, skiing in the winter);
- water procedures - rubbing with cool water is recommended; too hot baths are not recommended.
Find something favorable ideal condition for life, considering weather influence per person, very difficult. Optimal treatment of weather dependence should be aimed at increasing the elasticity of the walls of blood vessels. Strengthen cardiovascular system, align the mental and emotional background. To feel more comfortable, doctors recommend taking natural adaptogens for a weather-dependent person, such as tinctures of ginseng, eleutherococcus, and hawthorn.
Atmospheric pressure is considered normal within the range of 750-760 mm Hg. (millimeters of mercury). During the year it fluctuates within 30 mmHg. Art., and during the day - within 1-3 mm Hg. Art. A sharp change in atmospheric pressure often causes a deterioration in health in weather-sensitive people, and sometimes in healthy people.
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.
High barometric pressure and hypertension
If the atmospheric pressure is high (above 760 mm Hg), there is no wind and precipitation, they speak of the onset of an anticyclone. During this period no sharp changes temperature. 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 negative influence 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. Possible development of other dangerous complications(embolism, thrombosis, coma).
Low atmospheric pressure
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 amounts of fruit is recommended.
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 exclude physical exercise. If possible, you should be in an air-conditioned room. Will be relevant low calorie diet. Increase the amount of potassium-rich foods in your diet.
Atmospheric air is a gas mixture that has physical density and is attracted to the Earth. The weight of the air mass presses on the human body with great strength, which in numerical terms is about 15 tons (1.033 kg/cm2). This load is balanced by tissue fluids of the body, enriched with oxygen, but the balance is upset if the force of the external air changes for any reason. In the era of global climate change it's worth figuring out which atmospheric phenomenon the norm for a person, what it depends on, what measures should be taken to eliminate discomfort.
From a physical point of view, the atmospheric pressure equal to 760 mm Hg is taken as the standard. column: it is recorded at sea level in the Paris region at an air temperature of +15 o C. This indicator is rarely recorded in most of the Earth. In the lowlands, plains, hills, and highlands, the air presses on a person with unequal force. According to the barometric formula, when rising from sea level for every kilometer, there is a pressure drop of 13% compared to ideal, and when lowering (for example, into a mine) there is an increase by the same amount. In addition, barometer readings depend on climate zone, degree of air heating during the day.
Please note: Pressure 760 mm Hg. column corresponds to 1013.25 hPa in international system units. Otherwise, this indicator is called the standard atmosphere (1 atm).
When figuring out what atmospheric pressure is considered normal for a person, it should be noted: it should be comfortable, provide conditions for wellness, do not reduce performance, do not cause pain. IN different zones globe standards differ because people have adapted to local weather and climate conditions. Comfortable barometer readings for inhabitants of flat and slightly elevated areas of the planet are 750-765 mm Hg. Art., for residents of mountains and plateaus the numbers decrease.
In the regions of Russia, the values of the standards also differ from each other. On weather maps The territory of the Russian Federation, using isobar lines, is conventionally divided into zones, each of which has approximately the same pressure (it also fluctuates throughout the year). For convenience, you can use a table that shows normal atmospheric pressure in mm Hg. pillar and its possible deviations for different cities of Russia.
City name | Average annual pressure, mm Hg. | Permissible maximums (according to long-term observations), mm Hg. |
Moscow | 747-748 | 755 |
Saint Petersburg | 753-755 | 762 |
Samara | 752-753 | 760 |
Tula | 746-747 | 755 |
Yaroslavl | 720-752 | 758 |
Rostov-on-Don | 740-741 | 748 |
Izhevsk | 746-747 | 753 |
Ekaterinburg | 735-741 | 755 |
Chelyabinsk | 737-744 | 756 |
Permian | 744-745 | 751 |
Tyumen | 770-771 | 775 |
Vladivostok | 750-761 | 765 |
When moving, most people gradually adapt to changing natural and climatic conditions, although mountaineers constantly feel discomfort in the lowlands, despite the length of stay in such an area.
The effect of pressure changes on the body
According to doctors, the optimal degree of exposure to the atmosphere on each of us is not assessed in average regional figures. An indicator that the mercury column pressure level is normal is satisfactory physical state specific person. But there are common tendencies for all to deteriorate well-being under certain conditions.
- Daily fluctuations of 1-2 barometer divisions do not have any negative impact on health.
- Moving the mercury column up or down by 5-10 units has a more noticeable effect on well-being, especially with a sudden change in weather. If large pressure amplitudes are typical for a given region, local residents they are accustomed to them, and visitors will react to these jumps more strongly.
- When climbing mountains 1000 m, when the pressure drops by 30 mm Hg. pillar, some people experience fainting - this is a manifestation of the so-called mountain sickness.
The short answer to the question of what normal atmospheric pressure is optimal for a person is: the one that he does not notice. Fast movement mercury column in one direction or another at a speed of more than 1 mm Hg. Art. 3 hours causes stress even in a healthy body. Many people feel slight discomfort, drowsiness, fatigue, and increased heart rate. If these signs are more pronounced, we're talking about about weather dependence.
At-risk groups
An aggravated reaction to atmospheric processes is typical for people with various pathologies. When the pressure in the atmosphere fluctuates, the pressure in all body cavities (blood vessels, pleura of the lungs, joint capsules) changes more sharply, as a result of which the baroreceptors are irritated. These nerve endings transmit pain signals to the brain. More than others are prone to poor health due to weather phenomena the following patient groups:

Symptoms of health problems at high and low atmospheric pressure
When, as a result of the movement of air masses normal pressure the atmosphere is replaced by a higher one, an anticyclone sets in. If a low pressure area develops in a region, it is a cyclone. During periods of ups and downs in the mercury column, the human body experiences different manifestations discomfort.
Anticyclone
Its signs are sunny, windless weather, stable temperatures (low in winter, high in summer), and lack of precipitation. High blood pressure negatively affects the condition of hypertensive patients, asthmatics, and allergy sufferers. The arrival of an anticyclone is indicated by the following signs:

Cyclone
It is characterized by unstable temperature, high humidity, cloudiness and precipitation. Hypotensive patients, heart patients, and patients with gastrointestinal diseases are most susceptible to the influence of the cyclone. A decrease in atmospheric pressure affects the body in the following way:
- Blood pressure drops, heart rate slows;
- breathing becomes difficult, shortness of breath increases;
- intracranial pressure increases, migraine begins;
- activity is disrupted digestive system, gas formation is activated.
It is especially important to neutralize the effect of an approaching cyclone or anticyclone if weather dependence is caused by diseases of the heart, blood vessels, nervous system, respiratory organs. Older people, whose well-being often depends on changes in atmospheric pressure, should also act proactively.
Comprehensive plan preventive measures, compiled on the basis of medical recommendations and practical experience, will help not only alleviate suffering, but strengthen the body and make it less vulnerable to weather changes.

Coping with internal discomfort unfavorable days The following tips will help:
- in the morning it is better to take a contrast shower, then it is useful for hypotensive patients to cheer up with a cup of coffee (this can also be done with mild form hypertension, only the drink should not be strong);
- It is recommended to drink during the day green tea with lemon, do whatever you can physical exercise, eat less salty foods;
- in the evening it is advisable to relax with the help of decoctions of lemon balm or chamomile with honey, valerian infusion or glycine tablets.
