Our land has an atmosphere that puts pressure on everything is inside it. In 1634, the Italian scientist Torricelli first determined the value that is equal to atmospheric pressure. The impact on the person of his changes is learning scientists of various specialties. As it turned out, atmospheric pressure depends on temperature, air density, height, attraction force, terrain latitude. It is subject to constant fluctuations.
What atmospheric pressure is considered normal? What is it equal? Physics answer: 760 millimeters mercury pillar. Measurement should be carried out exactly at sea level, and the temperature must correspond to 15 degrees.
Square centimeter of the body normal pressure acts as a weight equal to 1,033 kg, but we do not notice it. This is because air gases are dissolved in tissue fluids. They fully balance the pressure of the atmosphere. Violation of equilibrium with weather change is perceived as deterioration of well-being. What atmospheric pressure is considered normal? Obviously, that that does not have negative influence on the body. According to physicians, it is 750 mm. RT. Art.
However, people living in places below or above sea level in a constantly increased or reduced pressureAdapting, it is well tolerated. Therefore, which atmospheric pressure is considered normal for health, it also depends on our adaptation.
Negative influence has not so much atmospheric pressure as its rapid changes. Falls or pressure lifts cause deterioration of well-being, heart problems. immature. But with the rapid change in its air, which is in various cavities of the body, acts on the baroreceptors internal organs. Part of people appears ailment, joint pain, pressure jumps and other unpleasant phenomena are observed.
For example, drumpipes hurt, worried abdominal pain. This is caused by the fact that the air located in the body cavities presses on their walls. This is especially felt during cyclones. Anticyclones have a smaller negative effect on the body.
Heart pains, heartbeats, heart rate disorders may appear. Dizziness, heartaches, breathing difficulty - these are the most typical complaints. Nervous system Reacts with increased anxiety, irritability. Some people enhance aggressiveness, conflict. The wines of the entire impulses coming from the baroreceptors in the brain during the change of atmospheric pressure.
The dependence of well-being from weather is that meteo-dependence. It is most pronounced in people with chronic diseases of the vessels, hearts, lungs and joints.
What atmospheric pressure is considered normal in your area, you can learn on the meteorological station. Usually, meteorologists in the preparation of predictions pressure at each specific point lead to pressure at sea level in a special formula.
The change in the pressure of the atmosphere is of particular importance when lifting to a large height. High in the mountains decreases this leads to a decrease in the saturation of the blood and the development of hypoxia - high-altitude, or mountain, illness. On the big height May develop swelling of the lungs, leading in the absence of treatment to death.
When depressurizing the aircraft cockpit at high height, a sharp drop in pressure leads to the fact that all fluids of the human body boil. Aerial embolism of vessels, paralysis, paresis and heart attacks of various organs develop.
Atmosphere pressure It is necessary to take into account not only when lifting a large height, but also in the work related to the transition to Wednesday with reduced or for this use special cable cameras. Violation of safety techniques during operation in them can lead to caisson disease.
If you suffer meteo-dependence, follow the weather forecasts. On time, the accepted medicines will allow you easier to transfer atmospheric pressure jumps.
Many people are subject to change in environment. The third part of the population is affected by the attraction of air masses to the ground. Atmospheric pressure: the norm for a person, and how deviations from the indicators affects general well-being of people.
Changes in weather may affect human condition
What atmospheric pressure is considered normal for humans
Atmospheric pressure is the weight of the air, which presses on the human body. On average, it is 1,033 kg per 1 cubic see that is 10-15 tons of gas every minute control our mass.
The rate of atmospheric pressure is 760 mm mercury column or 1013.25 mbar. The conditions in which the human body feels comfortable or adapted. In fact, the perfect weatheropeaurator for any resident of the Earth. In fact, everything is wrong.
Atmospheric pressure is not stable. Its changes are daily and depend on weather, relief, level over the sea, climate and even time of day. Oscillations are not noticeable for a person. For example, at night, the mercury column rises above 1-2 divisions. Minor changes do not affect well-being healthy man. Dresses in 5-10 and more units are painful, and sudden significant races are deadly. For comparison: the loss of consciousness from the mountainous disease has already been found when pressure drops by 30 units. That is, at the level of 1000 m above the sea.
Continent and even separate country can be divided into conditional areas with various norm average pressure. Therefore, the optimal atmospheric pressure for each person is determined by the permanent residence region.
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. It happens when the restructuring is impossible. So the inhabitants of the mountains suffer from poor well-being in the lowland, no matter how long there is no time there.
Doctors confirm the theory that the appropriate level of pressure is measured not with numbers, but individual well-being. Nevertheless, the optimal value for the average person is within 750-765 mm.
Atmospheric pressure standards in different regions
In each region of Russia, an individual pressure level has been formed. In Moscow, the ideal 760 mm practically does not happen. The average value is 747-749 units. For Muscovites, not significantly increased up to 755 mm. Values \u200b\u200babove sometimes affect well-being. Moscow stands on the hill, because the pressure above the average priori is impossible. In the Moscow region of division holds even lower: the territory is located above the capital.
Table "The rate of atmospheric pressure for the cities of Russia"
In Donetsk, atmospheric pressure is also different from the area. In the city, the average is 744-745 mm, and settlements Closer to sea level - 749-750.
What impact has atmospheric pressure per person
Atmospheric and blood pressure are interrelated. Lowering mbar (cloudy, rainy weather) is reflected in the body:
- decrease in blood pressure;
- drowsiness and apatine;
- reduced pulse frequency;
- breathing difficulties;
- fast fatigue;
- dizziness and pain;
- nausea;
- problems with the gastrointestinal tract;
- migraine.
During rainy weather There is a feeling of drowsiness
In the risk group of hypotoniki and face with oppressed respiratory functions. Their well-being on such days is distinguished by aggravated symptoms and attacks. Cases of a hypotonic crisis are rapidly.
Increased air pressure (clear, dry, windless and warm weather) Brings oppressed well-being hypertensive. Symptoms are opposite:
- an increase in blood pressure;
- rapid heart rhythm;
- red face;
- headache;
- noise in ears;
- dizziness;
- pulsation in temples;
- before your eyes;
- nausea.
High air pressure negatively affects hypertensive
Similar weather conditions are generous for strokes and heart attacks.
Persons who are vulnerable to nature caprics, doctors advise on such days to stay outside the area of \u200b\u200bactive work and deal with the consequences of meteo-dependence.
Meetability - what to do?
Mercury movement is more than one division for 3 hours - a reason for stress at a strong organism of a healthy person. Such oscillations feels each of us in the form of headaches, drowsiness, fatigue. More than a third of people suffer from meteo-dependence in varying degrees severity. In the high sensitivity zone, the population with diseases of cardiovascular, nervous and respiratory system, elderly people. How to help yourself if a dangerous cyclone is near?
15 ways to survive meteocyclone
There are not so many new advice here. It is believed that in the aggregate they facilitate suffering and teach right image Lifestyle at meteauceability:
- We regularly go to the doctor. Consult, discuss, ask the Council in case of worsening well-being. Have always under hand prescribed drugs.
- Buy a barometer. It is more productive to keep the weather on the movement of a mercury post, and not pain in the knee. So you will be able to foresee an impending cyclone.
- Follow the weather forecast. Forewarned is forearmed.
- On the eve of the change of weather, get enough sleep and lie down before usual.
- Strain sleep mode. Provide a full-fledged 8-hour sleep, lifting and falling asleep at one time. This has a powerful restricted effect.
- The power chart is equivalent to important. Watch out for a balanced diet. Potassium, magnesium and calcium - mandatory minerals. Ban on overeating.
- Drink vitamins with spring and autumn.
- Fresh air, walks on the street - Lightweight and regular loads strengthen the heart.
- Do not overvolt. To postpone household deeds is not as dangerous how to disseminate the body in front of the cyclone.
- Copy favorable emotions. The oppressed emotional background feeds the disease, and therefore smile more often.
- Clothing from synthetic threads and fur is harmful to static current.
- Store folk ways Removing symptoms in a prominent place. The recipe for herbal tea or compress is difficult to remember when the whiskey is leaving.
- Office workers in high-rise buildings suffer from weather change more often. Take the ran away if possible, and better change the job.
- Long-term cyclone - discomfort for several days. Is it possible to go to a calm region? Forward.
- Prevention Minimum per day before the cyclone prepares and strengthens the body. Do not give up!
Do not forget to take vitamins to promote health
Atmosphere pressure- This is a phenomenon that is absolutely independent of man. Moreover, our body obeys him. What should be the optimal pressure for a person determines the region of residence. Mately dependent people with chronic diseases.
In which the pressure is equilibrated by a column of fluid. It is often used as a liquid because it has a very high density (≈13,600 kg / m³) and low pressure saturated para at room temperature.
Atmospheric pressure at sea level is approximately 760 mm Hg. Art. Standard atmospheric pressure is taken equal to (exactly) 760 mm Hg. Art. , or 101 325 Pa, from here implies the definition of a millimeter of a mercury pillar (101 325/760 PA). Several other definition was previously used: the pressure of the mercury pillar is 1 mm high and a density of 13.5951 · 10 3 kg / m³ while accelerating the free fall 9,806,65 m / s². The difference between these two definitions is 0.000 014%.
Millimeters of mercury pillar are used, for example, in vacuum technique, in meteorological reports and when measuring blood pressure. Because the vacuum technique is often the pressure is measured in millimeters simply omitting the word "Hg" for a natural transition to vacuum systems micrometers (microns) is generally carried out also without "Hg pressure." Accordingly, when the pressure of 25 microns is indicated on the vacuum pump, we are talking about the limiting vacuum created by this pump measured in the microns of the mercury pillar. Of course, no one uses Torricechelli manometer to measure such low pressures. For measuring low pressures, other instruments are used, for example, a pressure gauge (vacuum meter) of Mac-Loda.
Sometimes high water column millimeters are used ( 1 mm RT. Art. \u003d. 13,5951 mm waters. Art. ). In the United States and Canada, also uses a unit of measurement "Inch mercury pillar" (Designation - INHG). one inhg. = 3,386389 kPa at 0 ° C.

Approximately the third part of our planet's population is sensitively reacting to environmental changes. Most of all, atmospheric pressure is affected by the atmospheric pressure - attraction of air masses to the ground. What atmospheric pressure is considered normal for a person - it depends on the terrain in which it remains an overwhelming part of the time. Every comfortable conditions will seem familiar to it.
What is atmospheric pressure
The planet is looking for an air mass, which under the influence of gravity presses for any subject, including human body. The force is called the pressure of the atmosphere. For each square meter Pressing the air post weighing about 100,000 kg. The measurement of atmospheric pressure is performed by a special device - barometer. It is measured in pascals, millimeters of a mercury pillar, millibares, hectopascals, atmospheres.
The rate of atmospheric pressure is 760 mm Hg. Art., or 101 325 Pa. The opening of the phenomenon belongs to the well-known physics Tell Pascal. The scientist formulated the law: at the same distance from the center of the Earth (it does not matter, in the air, at the bottom of the reservoir), the absolute pressure will be the same. He also suggested measuring the height by the method of barometric alignment.
Norms of atmospheric pressure by region
Find out what atmospheric pressure is considered normal for a healthy person, it is impossible - there is no definite answer. By different regions globe The impact of unequal. Within a relatively small area, this value may vary noticeably. For example, in Central Asia Standard are considered slightly increased numbers (an average of 715-730 mm Hg. Art.). For middle strip Russia is a normal atmospheric pressure equals 730-770 mm Hg. Art.
Indicators are associated with climbing surfaces above sea level, wind direction, humidity and ambient temperature. Warm air Weighs less than cold. Above the area C. increased temperature Or humidity compression of the atmosphere is always less. People living in highland regions are not sensitive to such indicators of the barometer. Their body was formed under these conditions, and all organs have passed the appropriate adaptation.
How pressure affects people
The perfect is the value of 760 mm Hg. Art. What is waiting for a mercury post when hesitate:
- Changes in optimal indicators (up to 10 mm / h) already leads to deterioration of well-being.
- With a sharp increase, lowering (on average, 1 mm / h), even healthy people have a significant deterioration in state of health. Headache appears, nausea, loss of performance.
Meetability
Human sensitivity to weather conditions - wind change, geomagnetic Buryam - Call meteo-dependence. The effect of atmospheric pressure on to the end has not yet been studied. It is known that when changing weather conditions Created internal stress inside vessels and cavities of the body. Meetable dependence can be expressed:
- irritability;
- pains of different localization;
- exacerbation of chronic diseases;
- general worsening of well-being;
- problems with vessels.
In most cases, people with the following diseases suffer from meteo-dependence:
- diseases respiratory tract;
- metabolic disorders;
- hypo and hypertension.
High pressure reaction
Reduced barometer indicators at least 10 units (770 mm Hg. Art. And below) negative influence on health. Particularly suffer from weather changes, people with long-standing diseases of cardiovascular and digestive system. Doctors on such days recommend to reduce physical exercise, less to go outside, do not abuse heavy food and alcohol. Among the main reactions:
- feeling of the mortgage of hearing aisters;
- reducing the number of leukocytes in the blood;
- reducing the activity of intestinal peristals;
- violation of the functionality of the cardiovascular system;
- weak ability to concentrate attention.

Atmospheric air has physical density, as a result, attracts to Earth and creates pressure. In the process of the development of the planet, he changed both the composition of the atmosphere and its atmospheric pressure. Living organisms were forced to adapt to the existing pressure of the air, changing their physiological characteristics. Deviations from average atmospheric pressure cause changes in human well-being, while the degree of sensitivity of people to such changes is different.
Normal atmospheric pressure
The air extends from the surface of the Earth to the height of the order of hundreds of kilometers, followed by the interplanetary space, while, the closer to the ground, the more air is compressed under the action own weight, respectively, the atmospheric pressure is above all ground surfaceDechanging with an increase in height.
At sea level (from which all heights are made), at a temperature of +15 degrees Celsius, the atmospheric pressure is an average of 760 millimeters of mercury pole (mm Hg. Art.). This pressure is assumed to be normal (from a physical point of view), which does not mean that this pressure is comfortable for a person under any conditions.
Atmospheric pressure is measured by a barometer, graded in millimeters of a mercury pillar (mm Hg. Art.), Or otherwise physical unitsFor example, in Pascals (PA). 760 millimeters of the mercury column correspond to 101 325 Pascals, but in everyday life, the measurement of atmospheric pressure in Pascals or derivatives (hectopascals) did not fit.
Previously, atmospheric pressure was also measured in millibars, which came out of consumption and replaced by hectopascals. The rate of atmospheric pressure is 760 mm Hg. Art. corresponds to the rate of atmospheric pressure in 1013 mbar.
Pressure 760 mm Hg. Art. Corresponds to the action for each square centimeter of human body strength 1,033 kilograms. Total for the entire surface of the body of a person, air presses with force of about 15-20 tons.
But a person does not feel this pressure, since it is balastinated in the tissue fluids of air gases. This equilibrium is violated with changes in atmospheric pressure, which person perceives as a deterioration of well-being.
For separate locations, the average atmospheric pressure is different from 760 mm. RT. Art. So, if in Moscow the average pressure is 760 mm Hg. Art., then in St. Petersburg only 748 mm Hg. Art.
At night, the atmospheric pressure is slightly above the daytime, and on the poles of the Earth the oscillations of atmospheric pressure are more pronounced than in equatorial zoneWhat only confirms the pattern that the polar regions (Arctic and Antarctica) as a habitat hostile to man.
The physics shows the so-called barometric formula, according to which, with an increase in height for each kilometer, atmospheric pressure drops by 13%. Real air pressure distribution follows barometric formula Not quite accurately, as depending on the height, the temperature, the composition of the atmosphere, the concentration of water vapor and other indicators changes.
Atmospheric pressure depends on the weather when air masses move from one terrain to another. All living on Earth react to atmospheric pressure. So, fishermen know that the rate of atmospheric pressure for fishing is reduced, because when pressure decreases predatory Fish Prefers to go hunting.
Weather-dependent people, and their planet 4 billion, react sensitively to changes in atmospheric pressure, and some of them can accurately predict the weather changes, guided by their well-being.
Answer the question of what the rate of atmospheric pressure is most optimal for the person's stay and life of a person, it is quite difficult because people adapt to life in different climatic conditions. Typically, the pressure ranging from 750 to 765 mm RT. Art. Does not impair human well-being, these values \u200b\u200bof atmospheric pressure can be considered limits.
With atmospheric pressure drops, meteo-dependent people can feel:
- headache;
- spasms of blood circulation violations;
- weakness and drowsiness with increased fatigue;
- pain in the joints;
- dizziness;
- feeling of numbness in the limbs;
- reduction of the pulse rate;
- nausea and intestinal disorders;
- shortness of breath;
- reducing visual acuity.
On the change in pressure, the first cases react in the cavities of the body, joints and blood vessels Baroreceptors.
With the change of pressure in the weather-sensitive people, there are violations in the work of the heart, the severity in the chest, pain in the joints, and the meteorism and intestinal disorders and intestinal disorders. With a significant decrease in pressure, the lack of oxygen in brain cells leads to headaches.
Also, pressure changes can lead to mental violations - people feel anxious, irritation, sleep restlessly either, in general, can not sleep.
Statistics confirms that with sharp changes in atmospheric pressure, the number of offenses, accidents on transport and production increases. The effect of atmospheric pressure on arterial is traced. In hypertensive, high atmospheric pressure can cause hypertensive crisis with headache and nausea, despite the fact that at this moment clear solar weather is installed.
The hypotoniki react to the decrease in atmospheric pressure, opposite. The reduced oxygen concentration in the atmosphere causes them a circulatory disruption, migraine, shortness of breath, tachycardia and weakness.
Weetto-sensitivity can be a consequence of an unhealthy lifestyle. The following factors can lead to meteo-sensitivity or aggravate the degree of its manifestation:
- low physical activity;
- incorrect power with concomitant overweight;
- stress and constant nervous voltage;
- poor state of the external environment.
The elimination of these factors reduces the degree of meteo-sensitivity. Meetable-dependent people should:
- include in the diet products with high content of vitamin B6, magnesium and potassium (vegetables and fruits, honey, lactic acid products);
- limit meat eating, salt and fried food, sweets and spices;
- refuse smoking and drinking alcohol;
- increase physical activity, make pedestrian walks in the fresh air;
- sort a dream, sleep at least 7-8 hours.

Many people are subject to changes in the environment. The third part of the population is affected by the attraction of air masses to the ground. Atmospheric pressure: the norm for a person, and how deviations from the indicators affects the general well-being of people.
Changes in weather may affect human condition
What atmospheric pressure is considered normal for humans
Atmospheric pressure is the weight of the air, which presses on the human body. On average, it is 1,033 kg per 1 cubic see that is 10-15 tons of gas every minute control our mass.
Its generally accepted norm is 760 mm mercury column or 1013.25 mbar. The conditions in which the human body feels comfortable or adapted. In fact, the perfect weatheropeaurator for any resident of the Earth. In fact, everything is wrong.
Atmospheric pressure is not stable. Its changes are daily and depend on weather, relief, level over the sea, climate and even time of day. Oscillations are not noticeable for a person. For example, at night, the mercury column rises above 1-2 divisions. Minor changes do not affect the well-being of a healthy person. Dresses in 5-10 and more units are painful, and sudden significant races are deadly. For comparison: the loss of consciousness from the mountainous disease has already been found when pressure drops by 30 units. That is, at the level of 1000 m above the sea.
Continent and even a separate country can be divided into conditional areas with different average pressure norm. Therefore, the optimal atmospheric pressure for each person is determined by the permanent residence region.
An example of the distribution of atmospheric pressure over Russia in January
A flexible human body has the potential to adapt to unfamiliar conditions. The notorious resort acclimatization is an example. It happens when the restructuring is impossible. So the inhabitants of the mountains suffer from poor well-being in the lowland, no matter how long there is no time there.
Doctors confirm the theory that the appropriate level of pressure is measured not with numbers, but individual well-being. Nevertheless, the optimal value for the average person is within 750-765 mm.

In Donetsk, atmospheric pressure is also different from the area. In the city, the average 744-745 mm, and settlements closer to the sea level - 749-750.
What impact has atmospheric pressure per person
Atmospheric and blood pressure are interrelated. Lowering mbar (cloudy, rainy weather) is reflected in the body:
- decrease in blood pressure;
- drowsiness and apatine;
- reduced pulse frequency;
- breathing difficulties;
- fast fatigue;
- dizziness and pain;
- nausea;
- problems with the gastrointestinal tract;
- migraine.
During rainy weather, a sense of drowsiness appears
In the risk group of hypotoniki and face with oppressed respiratory functions. Their well-being on such days is distinguished by aggravated symptoms and attacks. Cases of a hypotonic crisis are rapidly.
Increased air pressure (clear, dry, windless and warm weather) brings oppressed well-being hypertensive. Symptoms are opposite:
- an increase in blood pressure;
- rapid heart rhythm;
- red face;
- headache;
- noise in ears;
- dizziness;
- pulsation in temples;
- "Flies" before your eyes;
- nausea.
High air pressure negatively affects hypertensive
Similar weather conditions are generous for strokes and heart attacks.
Persons who are vulnerable to nature caprics, doctors advise on such days to stay outside the area of \u200b\u200bactive work and deal with the consequences of meteo-dependence.

15 ways to survive meteocyclone
There are not so many new advice here. It is believed that in aggregate, they facilitate suffering and teach the right lifestyle at meteauceability:
- We regularly go to the doctor. Consult, discuss, ask the Council in case of worsening well-being. Have always under hand prescribed drugs.

- Follow the weather forecast. Forewarned is forearmed.
- On the eve of the change of weather, get enough sleep and lie down before usual.
- Strain sleep mode. Provide a full-fledged 8-hour sleep, lifting and falling asleep at one time. This has a powerful restricted effect.
- The power chart is equivalent to important. Watch out for a balanced diet. Potassium, magnesium and calcium - mandatory minerals. Ban on overeating.
- Drink vitamins with spring and autumn.
- Fresh air, walks on the street - Lightweight and regular loads strengthen the heart.
- Do not overvolt. To postpone household deeds is not as dangerous how to disseminate the body in front of the cyclone.
- Copy favorable emotions. The oppressed emotional background feeds the disease, and therefore smile more often.
- Clothing from synthetic threads and fur is harmful to static current.
- Keep folk ways to relieve symptoms in a prominent place. The recipe for herbal tea or compress is difficult to remember when the whiskey is leaving.
- Office workers in high-rise buildings suffer from weather change more often. Take the ran away if possible, and better change the job.
- Long-term cyclone - discomfort for several days. Is it possible to go to a calm region? Forward.
- Prevention Minimum per day before the cyclone prepares and strengthens the body. Do not give up!
Do not forget to take vitamins to promote health
Atmosphere pressure
- This is a phenomenon that is absolutely independent of man. Moreover, our body obeys him. What should be the optimal pressure for a person determines the region of residence. Mately dependent people with chronic diseases.
Meetable people are more often interested in which atmospheric pressure is considered normal for humans. Weight aerial mass So great that the human body is withstanding the load over 15 tons. Do not feel such a load helps compensation, which is carried out by the pressure of internal organs. When, due to malfunction in the body, the adaptation system does not cope, a meteo-dependent person becomes a slave of weather cataclysm. The symptomy intensity depends on how low or high will be blood pressure.
What does the barometer mean?
It is known that the power of the pressure of the Earth's air shell per 1 cm² of the surface is equalized by the mercury with a height of 760 mm. This indicator is passed for the norm. When the barometer gives the result above 760 mm mercury pillars, they say an increased atmospheric pressure, when less than 760 mm Hg. Art. - About low. Given the fact that the surface of the earth is heated unevenly and non-uniform relief (mountain, lowlands) of the barometer will differ.

Favorable weather
Each person is unique. There will also be a unique rate of atmospheric pressure for it. Someone will not notice the flight to another climatic zone, And someone will feel the approach of the cyclone, which will manifest themselves with the headache and the "twisting" knees. Others climbed higher to the mountains and feel wonderful, not paying attention to the fired air. A combination of natural and weather conditions under which you can feel comfortable and there is a normal atmospheric pressure for a person. The older the person becomes, the stronger it feels climate change.

Table of optimal weather conditions
Everyone is experiencing an influence of not only the atmosphere pressure, but also air temperature, humidity both on the street and in the house. Optimal indicators I. possible consequences Normal deviations are filed in the table:
| Atmosphere pressure | 750-760 mm RT. Art. | above 760 mm Hg. Art. | less than 750 mm Hg. Art. |
| Influence | Comfortable for human well-being. |
|
|
| Air temperature | 18-20 ° C. | Above 25 ° C | Less than 16 ° C |
| Impact | Suitable for work, rest, sleep. | Excess air temperature, even 5 ° C, the norm leads to a significant decrease in performance, overwork. |
|
| Humidity | 50-55% | Less than 45% | More than 60% |
| Effect | Comfortable for well-being. | The mucous surface of the nasopharynx dries, its ability to withstand viruses and bacteria decreases. | The body resistance is reduced cold. |

What is meteo-dependence?
Meteo-dependence is the inability of the human body will adapt to changing weather conditions.
For meteo-dependence, people suffering from vegetative dystonia, hypertensive disease, atherosclerosis, and endocrine diseases are more predispose. Baroreceptors of our organs react to the approximation of cyclone or anticyclone, reducing or increasing blood pressure, making dependent on weather conditions.

The effect of high atmospheric pressure on arterial
The body has the ability to level atmospheric pressure with arterile.
The growth of atmospheric pressure forces blood pressure to align the imbalance. Arterial pressure Reduced, the walls of the vessels are expanding. The consequences of hypotension:
- worried bad state of health and general weakness;
- torment headaches;
- there is an unpleasant "concurrant" in the ears;
- chronic diseases are exacerbated.
The chemical composition of the blood under these conditions will show a decrease in leukocyte levels, which means that immune system It will be harder to cope with infection or virus. The best solution in such a situation:
- do not overvolt and relax well;
- limit the taking of alcoholic beverages at this time;
- enrich the diet with products containing potassium (dried fruits) and magnesium (cereal cereal, rye bread).

Effect of reduced atmospheric pressure per person
The fall in atmospheric pressure when changing the weather leads to the appearance of symptoms that are similar to mountain ascent. Insufficient amount of oxygen is unable to saturate human body organs. A shortness of breath appears, the heart knocks more often the pain presses in the temples and the hoop compresses his head. People with elevated intracranial pressure, head injuries, cardiovascular diseases react to this.

How to deal with meteo-dependence?
- food - limit consumption of fatty, salty food, focus on dairy products, fruits and vegetables;
- work is to balance the periods of rest and intensive work, more often take a break;
- sleep - it should be sufficient, not exceed 7-8 hours, a good solution - do not lie down later than 11 o'clock in the evening;
- exercise - regular, moderately intense (daily morning work-out, jogging in summer, walking in winter);
- water procedures - shown by cool water, too hot baths are not recommended.
Find favorable perfect condition for life, given weather influence per person, very difficult. The optimal treatment of meteo-dependence should be directed to an increase in the elasticity of the walls of the vessels. Strengthen the cardiovascular system, level the mental and emotional background. To feel more comfortable, the meteo-dependent person doctors recommend the reception of natural adaptogens, such as: Ginseng tincture, Eleutherococcus, hawthorn.
Atmospheric pressure is considered normal within the indicators of 750-760 mm Hg. (millimeters of mercury pillar). During the year, it varies within 30 mm Hg. Art., and during the day - within 1-3 mm Hg. Art. A sharp change in atmospheric pressure often causes degradation of well-being in meteo-dependent, and sometimes healthy people.
If the weather is changing, patients with hypertension feel bad. Consider how the atmospheric pressure on hypertensive and meteo-dependent people affects.
Meteo-dependent and healthy people
Healthy people do not feel any weather changes. Weather-dependent symptoms appear:
- Dizziness;
- Drowsiness;
- Apathy, lethargy;
- Articular pain;
- Anxiety, fear;
- Disorders of the GTS function;
- Vibrations of blood pressure.
Often, well-being is worsening in the fall, when the exacerbation of colds, chronic diseases is observed. In the absence of any pathologies, meteo-sensitivity is manifested by ailment.
Unlike healthy, meteo-dependent people react not only to atmospheric pressure fluctuations, but also to increase humidity, sudden cooling or warming. The reason for this is often:
- Low physical activity;
- The presence of diseases;
- Fall of immunity;
- Deterioration of the CNS state;
- Weak blood vessels;
- Age;
- Ecological situation;
- Climate.
As a result, the body's ability deteriorates to quickly adapt to changes in weather conditions.
High Atmospheric Pressure and Hypertension
If the atmospheric pressure is elevated (above 760 mm Hg. Art.), The wind and the precipitate are absent, they say the occurrence of anticyclone. During this period there are no sharp drops of temperature. The amount of harmful impurities increases in the air.
Anticyclone negatively acts on hypertensive. An increase in atmospheric pressure leads to an increase in blood pressure. The performance is reduced, pulsation and pain in the head, heart pain appear. Other symptoms of the negative effect of anticyclone:
- Heartbearance;
- Weakness;
- Noise in ears;
- Facial redness;
- Flashing "Flies" before your eyes.
The number of leukocytes is reduced in the blood, which increases the risk of developing infections.
Especially susceptible to anticyclone older people with chronic cardiovascular diseases. With an increase in atmospheric pressure, the probability of complication of hypertension - a crisis is increasing, especially if the blood pressure increases to the indicators of 220/120 mm RT. Art. Other hazardous complications are possible (embolism, thrombosis, coma).
Low atmospheric pressure
Poorly affects patients with hypertension and reduced atmospheric pressure - 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 is more frequent, pulse is studied, however, the power of cardiac beats is reduced. Some people appear shortness of breath.
At low air pressure drops and hell. Taking into account the fact that hypertensive is taking drugs to reduce pressure, cyclone poorly affects well-being. Symptoms appear:
- Dizziness;
- Drowsiness;
- Headache;
- Prostration.
In some cases, there is a worsening of the gastrointestinal tract.
With raising atmospheric pressure with hypertension and weather-dependent people Activated physical exertion should be avoided. We must rest more. A low-calorie diet containing an increased amount of fruit is recommended.
Even the "running" hypertension can be cured at home, without operations and hospitals. Just do not forget once a day ...
If the anticyclone is accompanied by heat, it is also necessary to exclude physical exertion. If it is possible, it is necessary to be indoors with air conditioning. There will be a relevant low-calorie diet. Increase in the diet the number of products rich in potassium.
