Our Earth has an atmosphere, to put pressure on all that is within it.In 1634 the Italian scientist Torricelli first determined value, which is equal to the atmospheric pressure.Impact on human study of its changes, scientists of different specialties.As it turned out, the atmospheric pressure is dependent on temperature, air density, altitude, attractive forces latitude.It is subject to constant fluctuations.
What is the atmospheric pressure is considered normal?What does it matter?Physicists say: 760 millimeters of mercury.The results should be exactly at sea level and the temperature should correspond to 15 degrees.
per square centimeter of the body normal pressure acts as a weight equal to 1,033 kg, but we do not notice.This is because air gases dissolved in the tissue fluids.They are fully equilibrated with atmospheric pressure.Imbalance when weather changes perceived as a deterioration of health.What is the atmospheric pressure is considered normal?Obviously, the one that has no adverse effects on the body.According to doctors, it is equal to 750 mm.Hg.Art.
However, people living in the areas above or below sea level in a constantly high or low blood pressure, adapting well it transferred.Therefore, what is considered normal atmospheric pressure health depends on our adaptation.
negative influence is not so much the pressure, as its rapid changes.Rises or falls in pressure causes deterioration of health, heart problems.Normal atmospheric pressure is imperceptible to humans.But with the rapid change in its air in the different cavities of the body, it acts on the baroreceptors of the internal organs.Do some people have discomfort, pain in the joints, there are pressure surges and other unpleasant phenomena.
example, sore eardrums, concerned about pain in the abdomen.This happens because the air in the cavities of the body, presses on their walls.This is especially felt during cyclones.Anticyclones have less negative impact on the body.
There may be pain in the heart, heart attacks, heart rhythm abnormalities.Dizziness, heart pains, shortness of breath - that's the most common complaint.The nervous system responds to increased anxiety, irritability.Some people have increased aggression and conflict.Blame the impulses coming from the baroreceptors to the brain during changes of atmospheric pressure.
dependence of being on the weather - that's what meteozavisimost.It is most pronounced in people with chronic diseases of blood vessels, heart, lungs and joints.
What is the atmospheric pressure is considered normal in your area, please visit the weather station.Usually the meteorologists in the projections in each pressure point leads to the pressure at sea level on a special formula.
change in atmospheric pressure is of particular importance in the rise to great heights.High in the mountains reduced partial pressure of oxygen.This leads to a reduction in saturation of the blood and the development of hypoxia - altitude or mountain, disease.At high altitude pulmonary edema may develop, resulting in the absence of treatment to death.
When the aircraft cabin depressurization at high altitude a sharp drop in pressure leads to the fact that all body fluids boil.Develops air embolism, paralysis, paresis and heart attacks various organs.
air pressure must be considered not only in the rise to great heights, but also in work connected with the transition to the environment with low or high pressure.To do this, use special cameras beamed.Violation of safety while working in them can lead to decompression sickness.
meteodependent If you are suffering, watch the weather forecast.At the time taken drugs will allow you to easily transfer jumps in atmospheric pressure.
