Our Earth has an atmosphere that puts pressure on everything inside it. In 1634, the Italian scientist Torricelli was the first to determine the value, which is equal to atmospheric pressure. The impact on a person of his changes is studied by scientists of various specialties. As it turned out, atmospheric pressure depends on temperature, air density, altitude, gravity, and latitude. It is subject to constant fluctuations.
What atmospheric pressure is considered normal? What is it equal to? Physicists answer: 760 millimeters of mercury. The measurement should be carried out exactly at sea level, and the temperature should correspond to 15 degrees.
For a square centimeter of a 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 completely balance the pressure of the atmosphere. Imbalance in weather changes is perceived as a deterioration in well-being. What atmospheric pressure is considered normal? Obviously, one that does not adversely affect the body. According to doctors, it is equal to 750 mm. Hg. Art.
However, people living in places below or above sea level in conditions of constantly high or low pressure, adapt, tolerate it well. Therefore, what atmospheric pressure is considered normal for health also depends on our adaptation.
The negative effect is exerted not so much by atmospheric pressure itself as by its rapid changes. Drops or rises in pressure cause a deterioration in well-being, heart problems. Normal atmospheric pressure for a person is imperceptible. But with a rapid change, its air, located in various body cavities, acts on the baroreceptors of internal organs. Some people have malaise, joint pain, pressure surges and other unpleasant phenomena.
For example, eardrums hurt, abdominal pains worry. This is due to the fact that the air in the cavities of the body presses on their walls. This is especially felt during cyclones. Anticyclones have less negative effects on the body.
Pain in the heart, heart attacks, heart rhythm disturbances may appear. Dizziness, heart pain, difficulty breathing - these are the most common complaints. The nervous system reacts with increased anxiety, irritability. Some people have increased aggressiveness, conflict. The blame for the pulses from the baroreceptors to the brain during a change in atmospheric pressure.
Dependence of well-being on the weather - this is what weather dependence is. It is most pronounced in people with chronic diseases of blood vessels, heart, lungs and joints.
You can find out what atmospheric pressure is normal in your area at a weather station. Usually, meteorologists, when making forecasts, the pressure at each particular point lead to pressure at sea level according to a special formula.
The change in atmospheric pressure is of particular importance when climbing to a great height. High in the mountains, the partial pressure of oxygen decreases. This leads to a decrease in their blood saturation and the development of hypoxia - high-altitude, or mountain, disease. At high altitude, pulmonary edema can develop, leading to death if untreated.
When depressurizing the cockpit at high altitude, a sharp drop in pressure leads to the fact that all the fluids of the human body boil. Air vascular embolism, paralysis, paresis and heart attacks of various organs develop.
Atmospheric pressure must be taken into account not only when climbing to a high altitude, but also when working with a transition to a medium with low or high pressure. To do this, use special caisson cameras. Violation of safety precautions while working in them can lead to decompression sickness.
If you are weather dependent, keep an eye on weather forecasts. Timely taken medications will make it easier for you to tolerate jumps in atmospheric pressure.
