What atmospheric pressure is normal?
Our Earth has an atmosphere that exerts pressureon everything that is inside it. In 1634, the Italian scientist Torricelli was the first to determine the value, which is equal to atmospheric pressure. The effect on the person of his changes is studied by scientists of various specialties. As it turned out, 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 square centimeter of the body is normal pressureacts 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 the doctors, it is 750 mm. gt; Art.
However, people living in places below or abovesea level in conditions of constantly high or low pressure, adapting, it is well tolerated. Therefore, what atmospheric pressure is considered normal for health, also depends on our adaptation.
The negative impact is not so much itselfatmospheric pressure, how many of its rapid changes. Falls or pressure rises cause deterioration 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, botherstomach ache. This is due to the fact that the air in the body cavities, presses on their walls. This is especially felt during cyclones. Anti-cyclones have less negative impact on the body.
There may be pain in the heart, attacksheartbeat, heart rhythm disturbances. Dizziness, heart pain, difficulty breathing - these are the most typical 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 inyour location, you can find out at the weather station. Usually, however, 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 has a specialvalue when climbing to a greater height. 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 to a largeheight, 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 should not be taken into accountonly when climbing to a higher altitude, but also for work related to the transition to a medium with reduced or elevated pressure. To do this, use special caisson chambers. Violation of safety during work in them can lead to caisson disease.
If you suffer from meteorological dependence, watch for weather forecasts. In time, the medications taken will allow you to more easily transfer the jumps of atmospheric pressure.
