The well-being of many people depends on weather conditions. In this case, we talk about weather dependence. What does mean atmospheric pressure mean and how does it affect the he alth of residents? How to minimize the consequences of his fluctuations? What is considered normal?
Standard condition
Atmospheric pressure is understood as the weight of air pressing on the human body and other objects on the earth's surface. This coefficient is 1.033 kg per 1 cm3. Our mass is controlled by 10-15 tons of gas every minute.
Average normal atmospheric pressure at 0 °C reaches 760 mm Hg. Specific values are the standard. The pressure is measured at sea level, so it is considered normal. Sometimes they say: “One atmosphere” or “Three atmospheres”. In the latter version, the pressure cannot be called the norm, since it exceeds the average by 3 times. Atmosphere refers to the standard mark.
The pressure is not stable, it fluctuates every day. Its indicators depend on the weather, relief, level above the sea, time of day and year, climate. The pressure changes due topropagation in the atmospheric layer of waves of various nature from sound to synoptic.
Slight changes in 2-3 divisions of the mercury column do not affect the state of he alth. A difference of 5-10 units leads to painful conditions. Jumps exceeding the previous figures several times can be fatal. So, in a mountainous landscape, when climbing to a height, consciousness is lost when the pressure drops by 30 units.
Nature made sure that the human body was flexible and able to adapt to any conditions. Acclimatization is a prime example of this. However, not all people can painlessly survive the change in climatic conditions. For example, the inhabitants of the mountains are not able to adapt to the weather in the lowlands.
Atmospheric pressure measurement
This parameter can be measured in pascals, bars, millimeters of mercury. The last unit is used in the barometer. Like the device itself, this name for the pressure unit is understandable to ordinary people. Therefore, they know what the average atmospheric pressure is when recording data with a barometer.
In physics they resort to pascals. The norm in this case is 101,325 Pa=760 mm. The last unit of measure is 1 bar=100,000 Pa. The standard is 1.01325 bar.
The influence of atmospheric pressure on the weather
As the average barometric pressure fluctuates between low and high, you can tell what the weather is going to be like in the next few days. Such a forecast is not particularly accurate. It all depends on many parameters. An accurate forecast is also difficult for the reason that the average atmospheric pressure varies for each region of the planet.
Anyone can orient themselves and say what the weather is expected to be. If the pressure falls below the average, it will soon be rainy and cloudy days. Sunny weather comes with an increase in the parameter.
In winter, the situation changes dramatically. With reduced pressure, warming and possible precipitation (snow) are expected. Increasing the parameter is a guarantee of clear weather, respectively, it will be frosty.
Pressure and man
Normal, low or high blood pressure are very conditional definitions. People can get used to and adapt to everything. It is more important to observe the dynamics and amplitude of the drops.
In million-plus cities, atmospheric pressure is considered as a variable value due to the large accumulation of skyscrapers. This type of building can be compared to a mountain. The more a person goes up and down in a high-speed elevator, the more acutely he reacts to pressure drops.
Doctors say that the pressure in the middle ear corresponds to atmospheric pressure. How else is the weather indicator related to human he alth?
Meteorological dependence
If the average value of atmospheric pressure fluctuates by more than 1 unit in 3 hours, then a he althy, strong body gets stressed. Any weather-dependent person has symptoms:drowsiness, migraine, fatigue. Among the most sensitive people are patients with diseases of the cardiovascular, nervous, and respiratory systems. The elderly are sensitive to minor fluctuations.
To minimize meteovulnerability, you must adhere to the following recommendations:
- follow the weather forecast;
- consult a doctor;
- get enough sleep;
- adjust sleep;
- balance your eating schedule and eating habits;
- drink vitamins;
- walk for a long time in the fresh air;
- do not overwork;
- buy a barometer and monitor the fluctuations of the mercury column.
Risk groups
With reduced atmospheric pressure, the risk group includes hypotension and people with impaired respiratory function. Because of these fluctuations, they most often experience seizures and exacerbation of symptoms. The risk of getting a hypotensive crisis is increasing.
Hypertension sufferers and people with diseases of the cardiovascular system suffer from high atmospheric pressure. On such days, the likelihood of dying with a heart attack or stroke increases.
Due to fluctuations in the mercury column, baroreceptors are irritated in the body. Nerve endings signal to the brain about the deterioration of well-being due to changes in the weather.
Atmospheric pressure fluctuations make patients feel worse:
- with diseases of the respiratory system: pleurisy, bronchitis, asthma, chest injuries;
- cardiovascular disease:hyper- and and hypotension, atherosclerosis;
- chronic diseases of the ear and olfactory organs: sinusitis, otitis, frontal sinusitis;
- impaired brain activity: increased intracranial pressure and trauma;
- diseases of the musculoskeletal system: rheumatism, arthrosis, osteochondrosis.
Symptoms of diseases at low or high atmospheric pressure
Signs of deterioration in he alth depend on the average atmospheric pressure at a particular point in time.
With a reduced rate, a person has:
- lower blood pressure;
- drowsiness, lethargy;
- decrease in heart rate;
- respiratory difficulties;
- dizziness and migraines;
- nausea;
- problems in the gastrointestinal tract;
- headaches;
- fatigue.
With increased atmospheric pressure, a person has the following symptoms:
- appearance of redness on the face;
- increased blood pressure;
- tinnitus;
- increased heart rate;
- black dots before eyes;
- nausea;
- pulsation in the temporal region;
- dizziness.
Feeling Better Tips
If the average atmospheric pressure has dropped or risen sharply, weather-dependent people have a hard time. The following tips will help you minimize weather damage and deal with internal discomfort:
- accept withmorning contrast shower;
- hypotonics and people with mild hypertension can drink a cup of weak coffee;
- during the day, green tea with lemon is the priority drink;
- s alt needs to be reduced;
- do your best physical exercise;
- for rest and relaxation in the evening, drink decoctions of soothing herbs, chamomile with honey or a glycine tablet.
Differences in atmospheric pressure cause mental disorders. Anxiety and irritation, insomnia or restless rest appear.
According to statistics, sudden changes in atmospheric pressure lead to an increase in accidents and offenses, industrial emergencies.
