What is the lowest atmospheric pressure? What atmospheric pressure is comfortable for humans?

One of the biggest troubles when fishing is the lack of bite. Every fisherman wants to know why this happens. If we ignore subjective reasons, such as poorly configured equipment, bad game bait, incorrectly chosen bait, etc. etc., then remain natural conditions, including pressure.

Atmosphere pressure- the pressure of the atmosphere located above a specific area of ​​the earth's surface. There is an opinion that the optimal pressure for fishing is 760 mm mercury, however, this is completely incorrect.

Any piece of land has a different height above sea level, therefore it is different, and this is worth taking into account. So, for the middle zone, the norm is 760 mm, but for Western Siberia normal pressure much lower - only 746 mm. The pressure also varies during the day by 1-3 mm, but the fish practically does not react to this.

The fish reacts to its more significant fluctuations.

Fishing at low and high pressure

According to the observations of fishermen, when the pressure drops, predatory fish begins to hunt more actively and it doesn’t matter whether there is wind or not, sunny or overcast, regardless of the time of day and phase of the moon.

Especially if it has dropped, after the weather had been stable with high atmospheric pressure for several days, the predators begin to really eat.

There is a hypothesis that they are trying to get enough before the weather changes, fearing that it will become much more difficult to do so later.

Atmospheric pressure drops with the arrival of a cyclone and rises with an anticyclone. Predatory fish begin to bite poorly several hours before the arrival of the anticyclone.

At high atmospheric pressure, the predatory fish becomes passive, but during this period the whitefish willingly bites. Without fear of predators, the white fish begins to look for food. The activity of the whitefish is observed from the moment the arrow begins to creep up and continues throughout the entire stabilization time.

Since with the arrival of the anticyclone, windy and clear days are established, therefore, it is in such weather that it is better to fish white fish. During this period, whitefish bite throughout the daylight hours.

The worst bite is observed with sudden pressure surges both down and up. At these moments, the fish seems to be in limbo, does not go to any of the baits and becomes active, or, conversely, stops eating only when stable pressure is established.

Consequently, it bites best when there are no sharp jumps that cause equally sudden changes in the weather.

Optimal atmospheric pressure for fishing

To say what pressure is best for fishing, you must first decide what you are going to catch. If the goal is to catch a predatory fish, then you need to wait until the barometer starts to fall.

The chances of returning with a rich catch are much higher. If you want to catch white fish, you will have to wait for the arrival of the anticyclone, and with it the sunny days. It is at this time that she takes the bait more actively.

Reasons for changes in fish behavior

The sense of touch of fish is vaguely similar to the principle of operation.

When moving, the fish creates barely noticeable waves, allowing it to navigate and determine the correct distance to various items located in the water column.

In addition, thanks to these waves, the fish accurately determines the depth at which it is located.

This works best for surface fish. The fish orients itself and determines the distances to various objects in the thickness of the reservoir according to a specific density. As the pressure rises, the water level drops slightly, causing its density to increase.

At the same depth, the fish begins to feel discomfort and moves higher. Now the waves created by the fish carry information that is unusual for it and it is necessary for some time to pass until it adapts.

After the acclimatization period is completed, the fish feels good closer to the surface of the water, where it is easier to get food. Therefore, the bite of white fish increases as soon as the barometer creeps up.

As the whitefish moves closer to the surface, the predators have no one to hunt, so their activity subsides.

As soon as the barometer starts to creep down, the white fish is not comfortable in upper layers and she sinks deeper. Again the waves it creates carry unfamiliar information; again the fish needs to get used to new conditions.

It is because of these periods of acclimatization that there is no bite during sudden pressure surges.

Having descended to the depths, the white fish again becomes a tasty prey for a predator. Therefore, when the barometer falls, predatory fish are more likely to bite.

Influence of atmospheric pressure depending on the season

Spring bite

The most wonderful time for fishing is early spring, when the water temperature begins to rise, a hungry predator, and most of the ichthyofauna actively bites on any bait.

The bite may drop due to gusty winds, a sharp drop in temperature and strong pressure surges.

From mid-April, the fish become more picky and willingly bite in light winds and stable weather throughout the day. She is also reluctant to take bait in cloudy waters, which is associated with melting snow.

Summer bite

When the water rises above 25 degrees, the fish becomes apathetic, and its behavior is highly dependent on atmospheric pressure. Cloudy but windless days are considered optimal weather for fishing. The predator takes bait well on days with short thunderstorms.

It is best to go fishing either at dawn or at night, when the temperature is slightly lower than during the day.

Autumn bite

As soon as the temperature drops, the fish begin to actively take the bait. It is better to choose for fishing in the autumn season warm days with light wind.

Pike bite more actively in September on cloudy days, until the first cold, then the bite drops. But carp breeds have low activity in the fall.

Winter bite

In winter, most fish are very susceptible to pressure fluctuations. If it has changed up and down several times in a short period of time, you should not expect a good bite, even if it stabilizes. It needs to stay at the same level for 2-5 days, then there will be a bite.

Whether there will be a bite or not depends very much on the combination of ambient temperature and pressure. So, if the barometer rises by 25-30 mm, and the thermometer drops by 7-12 degrees, you can’t expect a bite.

Also, there will be no bite if it drops by 9-11 mm and at the same time the temperature changes. The bite will resume only when these parameters stabilize.

The bite will be good if high pressure will be combined with low air temperatures, and low pressure will occur on days of thaw and mild frosts.

To decide which pressure is best for fishing, you must first decide what you want to catch and then, depending on the season, choose the optimal days for fishing.

Many people are subject to change in environment. A third of the population is affected by the attraction of air masses to the earth. 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.

The standard atmospheric pressure 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 your 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.

The continent and even an individual country can be divided into conventional areas with different average pressure levels. 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 unfamiliar 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:

• demotion 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;
• before your eyes;
• nausea.

High air pressure has a negative effect on hypertensive patients

Similar weather generous to strokes and heart attacks.

For people who are vulnerable to the vagaries of nature, doctors advise on such days to stay outside the active work zone and deal with 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 to varying degrees of severity. 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. It is believed that together they alleviate suffering and teach the correct way of life in case of weather vulnerability:

1. See your doctor regularly. Consult, discuss, ask for advice in case your health worsens. Always have prescribed medications on hand.
2. 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.
3. Keep an eye on the weather forecast. Forewarned is forearmed.
4. On the eve of a weather change, get enough sleep and go to bed earlier than usual.
5. 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.
6. Meal schedule is equally important. Maintain a balanced diet. Potassium, magnesium and calcium are essential minerals. Ban on overeating.
7. Take vitamins in a course in spring and autumn.
8. Fresh air, walks outside - light and regular exercise strengthens the heart.
9. Don't overexert yourself. Putting off household chores is not as dangerous as weakening the body before a cyclone.
10. Accumulate favorable emotions. Depressed emotional background fuels the disease, so smile more often.
11. Clothes made from synthetic threads and fur are harmful due to static current.
12. Store traditional methods symptoms relief list in a visible place. Recipe herbal tea or a compress is difficult to remember when your temples ache.
13. Office workers in high-rise buildings suffer more often from weather changes. Take time off if possible, or better yet, change jobs.
14. A long cyclone means discomfort for several days. Is it possible to go to a quiet region? Forward.
15. 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. What the optimal pressure should be for a person is determined by the region of residence. People with chronic diseases are especially susceptible to weather dependence.

Man is part of nature. It constantly influences each of us. The more time passes, the more weather-sensitive people appear. Today there are approximately 4 billion such people living on the planet. The factor that most strongly influences a person’s health and well-being is atmospheric pressure, or rather its norm. What atmospheric pressure is considered normal depends on geographical location the area where a person lives most time.

What is atmospheric pressure?

The Earth is habitable due to a number of factors. The first of these is the availability of breathing air. Our planet, like a dome, is covered with an atmosphere consisting of many layers, each of which performs a specific important function. The air mass exerts constant pressure on everything that is on Earth, including humans, so it is so important to know what its norm is. Every day, each of us withstands a load of approximately 15,000 kg. We do not feel this burden due to the unique structure of our body. But he can't always cope natural phenomena. Sometimes there is an imbalance in the organ system human body, and then a person becomes dependent on changes in atmospheric pressure.

Atmospheric pressure, which is the norm for a person living in middle lane Russia, is 750-760 mmHg. This is the indicator at which most people do not feel any discomfort in their health.

Any deviation of a person’s atmospheric pressure from the norm by 5-10 units or higher will be painfully accepted by our body.

Atmospheric pressure measurement

To measure the normal atmospheric pressure for a person, a specially designed device is used - a barometer. Science has established that the force of atmospheric pressure per 1 sq.cm. surface of the Earth, corresponds to the height of the mercury column of 760 mm. This indicator was taken as the norm of atmospheric pressure for humans. If the barometer reading is above this mark, it is customary to talk about increased pressure from normal. If the atmospheric pressure is below normal for a person, then it is considered low. Barometer readings in different parts of the planet differ due to differences in relief, temperature, etc.

The normal atmospheric pressure for a person is measured in mm of mercury (mmHg). Other units may be used, such as pascals (Pa). An indicator of 760 mmHg will be equal in this case to 101325 Pa. However, in ordinary life, measuring normal atmospheric pressure for humans in pascals has not taken root. Any weather forecast informs us about the state of atmospheric pressure using mmHg.

What is weather sensitivity?

Many people have so-called weather sensitivity. This is a peculiar reaction of the body to a change in the normal atmospheric pressure for a person. It can be expressed, depending on the presence of various health problems, in the appearance of irritability, pain in various parts of the body, a general decrease in performance, and insomnia. A change in normal atmospheric pressure for a person can manifest itself in mental disorders, for example, a state of anxiety, depression, unreasonable fear.

According to statistics, during sudden changes weather, even the number of offenses and transport accidents, as well as man-made disasters, grows several times.

The human body is a kind of chemical laboratory that works normally at the appropriate standard of atmospheric pressure for a person. As soon as these conditions change in any direction, the body reacts with painful manifestations. He lacks something, for example, oxygen. Or vice versa, there is something in excess.

The causes of weather sensitivity are not only health problems, but also poor lifestyle choices. A large role is played by sedentary activity, poor nutrition with subsequent acquisition overweight, stress.

The influence of human atmospheric pressure

In the vessels and cavities of the human body there are specific receptors that are very sensitive to any changes in atmospheric pressure standards for humans. For example, people with musculoskeletal disorders always “predict” weather changes by aching joints. Hypertensive patients due to headaches in the temples, etc.

The well-being of heart patients also worsens with changes in normal atmospheric pressure for humans. They feel pain in the heart and head, rapid heartbeat and other unpleasant symptoms.

High atmospheric pressure forces the human body to equalize the imbalance that has arisen. How does this happen? By reducing blood pressure. At the same time, the vessels relax, the speed of blood flow changes. Malaise, headaches, and stuffy ears occur. With increased atmospheric pressure, changes occur in chemical composition blood, in particular, the level of leukocytes, the main fighters against infections and viruses, decreases.

Low atmospheric pressure creates conditions for the body similar to climbing a mountain. Under such conditions, there is a deficiency of oxygen, and, consequently, the brain and other organs suffer from hypoxia. The person feels difficulty breathing, pain in the temporal region, and pressure in the head.

Scientists have discovered the dependence of atmospheric pressure on air temperature. With warming, atmospheric pressure decreases. This is unfavorable for hypotensive patients and asthmatics.

With the onset of cold weather and the establishment of clear weather, the norm becomes high. Hypertension sufferers, allergy sufferers, and kidney sufferers.

The most dangerous thing is a sharp increase in atmospheric pressure (by 1 mmHg in 2-3 hours). The patient feels sharply negative symptoms, feels very bad. It is imperative to monitor your blood pressure and immediately take the medications prescribed by your doctor.

A person cannot influence the weather, but he can help himself survive difficult periods.

The first thing you should do as much as possible is to reduce physical activity.

Secondly, consult your doctor about prescribing normal medical supplies for those who have a particularly hard time withstanding weather changes.

The optimal combination of weather indicators for a person is as follows:

• Atmospheric pressure is normal - 760 mmHg.
• Air temperature is the norm 18-20 ͦ C.
• Humidity is normal 50-55%.

At different points on the Earth, the pressure rate may be different. Recorded fluctuations at sea level are 641-816 mmHg. The average value is exactly 760 mmHg at 20 degrees Celsius. This does not mean that for every person this reading should be equal to the norm. If a person was born and raised in the mountains, the normal numbers for him will naturally be different. Climbing into the mountains will reduce the altitude by about 13% for every kilometer.

The average atmospheric pressure for St. Petersburg, located in northwestern Russia, is only 748 mmHg.

It is time that can greatly influence a patient’s barometric pressure. At night it is higher than during the day. That is why most attacks in heart patients occur at night.

Since 1982, a standard pressure of 100 kPa has been adopted.

Naturally, it is impossible to choose ideal conditions for yourself. How many people, so many problems. Everyone is concerned about certain disorders, so it is important to prepare yourself and your body for weather changes and take care of your health.

Atmospheric pressure affects all living organisms. From the article you will learn the normal atmospheric pressure and how changes in level affect a person.

Normal for humans

In medicine, it is believed that the normal atmospheric pressure for the average person is 750-760 mm Hg. Art.

A spread of 10 units of measurement between indicators is considered acceptable, since pressure parameters differ in places with different topography. So for residents of the high mountain region one pressure will be comfortable, and for residents of the plain - another. At the same time, the rapid movement of a person from one region to another can cause him unpleasant sensations due to changes in atmospheric pressure.

Analyzing the data on normal indicators of atmospheric pressure, we can judge that per 1 cm² of area the atmosphere presses with a force equal to the pressure of a mercury column, which has a height of 750-760 mm. With normal pressure levels, the human body feels comfortable. This is due to the fact that the body during for long years During the existence of man as a species, a balance developed between the pressure of air and its gases dissolved in tissue fluid.

Attention! Despite clearly established parameters for comfortable atmospheric pressure, different people, even from the same region, are able to tolerate the influence of air pressure differently. This is due to the varying ability of the human body to adapt to constantly changing conditions. external environment. That's why generally accepted indicators of normal atmospheric pressure should be considered averaged.

Measurement of atmospheric pressure in mmHg. Art. (millimeters of mercury) is carried out due to the generally accepted system associated with the historical factor. mmHg Art. is not a standard unit of measurement for atmospheric pressure. IN international system Standards of Measurement (SI) The unit for determining atmospheric pressure is the pascal (Pa). According to the SI measurement rules, an atmospheric pressure of 100 kPa (kilopascal) is considered normal. Pressure 750-760 mm Hg. Art. equals 99.95-101.32 kPa.

Air pressure is also measured in mm of water. Art. (mm of water column). According to this measurement, normal atmospheric pressure will be 10196.3-10332.2 mm of water. Art. However, such units of measurement are rarely used in practice in post-Soviet countries. Measuring atmospheric pressure in terms of the water column is mainly used in the countries of the American continent.

Effect on the body

Normal indicators of atmospheric pressure are rarely observed, and even less often they are maintained for a long time. Weather instability, the direction of air masses, terrain features, the influence of production (especially in industrial cities) lead to the fact that atmospheric pressure is constantly changing, generally accepted normal indicators quickly change to uncomfortable ones. In this regard, the body has to constantly adapt to them and adapt. However, not everyone is capable of this. Adaptation to pressure changes is difficult atmospheric air persons suffering from a number of diseases (especially chronic ones). Consider the impact different pressure atmosphere on the human body in groups.

Effect of increased atmospheric pressure

When high atmospheric pressure forms, the weather improves, the sky becomes clear, the air becomes warmer, becomes dry, and there are no surges in humidity. The body of a healthy person easily adapts to such parameters, without feeling any discomfort or pain. There is an uplift in mood, increased performance, increased energy reserves, improved mood, and a surge of energy.

In hypertensive patients whose blood pressure already elevated, the combination of atmospheric and blood pressure leads to a worsening of the condition. Such people note complaints about:

decreased ability to work;

constant weakness;

the appearance of headache;

heartache;

rapid heartbeat (tachycardia);

noise or ringing in the ears;

sweating;

facial redness;

the appearance of spots, spots before the eyes, clouding;

Possible nosebleeds

The negative impact of increased atmospheric pressure on a person is clearly manifested in patients with diseases of the immune system or suffering from chronic diseases, including those of an infectious nature. An increase in pressure leads to a decrease in the population of certain immune cells, which facilitates the conditions for the life of infections and enhances the processes of pathological metabolism. In allergy sufferers, in response to an increase in atmospheric pressure, progression of the pathological condition is noted.

In people suffering from hypotension (low blood pressure), on the contrary, with high atmospheric pressure, there is an improvement in their condition, the disappearance of pathological symptoms, their mood improves, their reserves of strength increase, and they feel comfortable. A similar picture is observed in patients with diseases of the joints, respiratory system (outside large city), digestive tract, nervous system(especially in people prone to depression, suffering from bipolar personality disorder, schizophrenia).

Attention! Due to air pollution major cities in persons suffering from diseases of the respiratory system, with increasing atmospheric pressure, a deterioration in their condition is observed. Therefore, they are not recommended to stay outside for a long time, even in good weather.

Effect of low atmospheric pressure

The effects of low atmospheric pressure are first felt by patients suffering from diseases of the cardiovascular system, people with glaucoma and those suffering from surges in intracranial pressure. Those suffering from glaucoma note pain in the eye, blurred vision (blurred vision, cannot see objects in the distance, discomfort in and behind the eye, etc.), weakness and headaches. People suffering from changes in intracranial pressure will complain of noise in the head and ears, headaches of varying severity (even unbearable), loss of performance, sleep disturbances, etc.

In hypotensive patients, for whom it is optimal high blood pressure atmosphere, there will be a significant deterioration in the condition (weakness, noise in the head and ears, drowsiness, dizziness, pain in the head and heart area, a constant feeling of lack of air, shortness of breath, possibly coughing and abdominal pain.). The condition of hypertensive patients, on the contrary, will improve. People suffering from migraines, with low atmospheric pressure, will notice the appearance of painful attacks, their intensification and increase in duration. Such persons feel good at high atmospheric pressure.

For patients with joint diseases, low atmospheric pressure acts as a trigger for exacerbation of pathological processes. Such a person will notice a stable deterioration in his condition, increased symptoms (pain, dysfunction of joints). A similar picture will be observed in patients with diseases of the respiratory system, organs digestive system. Low air pressure also has an adverse effect on patients with diseases of the urinary system (pathological symptoms increase).

Condition of patients with mental illness often depends on the degrees outside the window and the weather. Worsening weather (observed when atmospheric pressure drops) has a negative effect on the state of mind. Patients with similar diseases experience deterioration of their condition, exacerbation pathological symptoms. Low blood pressure has a positive effect on the state of the immune system - the synthesis of cells and biologically active substances is enhanced.

Important! You can find out more about what blood pressure is considered normal from your doctor, and, if necessary, he will prescribe treatment.

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 altitudes of the order of hundreds of kilometers, beyond which interplanetary space begins, while the closer to the Earth, the more the air is compressed under the influence of its own weight, respectively, the atmospheric pressure is highest at the 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 (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, 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. rt. 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, fluctuations in atmospheric pressure 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, since when the pressure drops, predatory fish prefer to go hunting.

Impact on human health

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 a person’s place of stay and 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.

Baroreceptors located in the body cavities, joints and blood vessels react first to changes in pressure.

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 when sudden changes atmospheric pressure increases the number of crimes, accidents in transport and production. 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, take walks in the fresh air;
• organize your sleep, sleep at least 7-8 hours.
