What atmospheric pressure is normal?

Our Earth has an atmosphere that exerts pressure on everything that is inside it. In 1634, the Italian scientist Torricelli was the first to determine the value, which is the atmospheric pressure. The effect on the person of his changes is studied by scientists of various specialties. As it turned out, the atmospheric pressure depends on temperature, air density, altitude, gravity, latitude. It is subject to constant fluctuations.

What atmospheric pressure is normal? What does 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.

The normal pressure acts on a square centimeter of the body as a weight equal to 1,033 kg, but we do not notice it. This is because the air gases are dissolved in the tissue liquids. They completely balance the pressure of the atmosphere. Violation of equilibrium in weather changes is perceived as a deterioration of well-being. What atmospheric pressure is normal? Obviously, the one that does not have a negative effect on the body. According to doctors, it is 750 mm. Gt; Art.

However, people living in places below or above sea level in conditions of constantly high or low pressure, adapting, are well tolerated. Therefore, what atmospheric pressure is considered normal for health, also depends on our adaptation.

Negative influence is exerted not so much by atmospheric pressure itself, as by its rapid changes. Falls or pressure rises cause a worsening of health, heart problems. Normal atmospheric pressure for a person is insensible. But with a rapid change in its air, located in different body cavities, acts on the baroreceptors of internal organs. Some people have malaise, joint pain, pressure jumps and other unpleasant phenomena.

For example, the eardrums ache, pain in the abdomen. This is due to the fact that the air in the body cavities, presses on their walls. Especially it is felt during cyclones. Anti-cyclones have less negative impact on the body.

There may be pain in the heart, palpitations, heart rhythm disturbances. 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. Blame for all the impulses coming from the baroreceptors in the brain during a change in atmospheric pressure.

Dependence of well-being on the weather - that's what meteorology is. It is most pronounced in people with chronic diseases of blood vessels, heart, lungs and joints.

What atmospheric pressure is considered normal in your area, you can find out at the weather station. Usually, meteorologists, when making forecasts, 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 higher altitude. High in the mountains decreases the partial pressure of oxygen. This leads to a decrease in the saturation of blood and the development of hypoxia - altitude, or mountain disease. At high altitude, pulmonary edema can develop, leading to death in the absence of treatment.

When the cockpit is depressurized at high altitude, a sharp drop in pressure leads to the fact that all the fluids of the human body begin to boil. An air embolism of the vessels, paralysis, paresis and infarctions of various organs develops.

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 a reduced or increased pressure. To do this, use special caisson chambers. The violation of safety during work in them can lead to caisson disease.

If you are suffering from meteorological dependence, watch for weather forecasts. In time, the medications taken will allow you to more easily transfer the jumps of atmospheric pressure.
