In ancient times, people first noticed the effect of air pressure on surrounding objects and people's health. Most of all, this was noticeable during natural disasters (hurricanes, storms, etc.). Until it was proved that air has weight, mankind could not explain at the expense of what many processes on the planet are related to, weather and people's well-being. The pressure that air exerts with its weight on the Earth and everything on it is called atmospheric. A person does not feel the heaviness of air, because atmospheric pressure is evenly distributed on the body. The norm of this effect is achieved by a balance between the external air pressure and the internal pressure of our body.
In international practice, atmospheric pressure is measured in pascals, millibars and millimeters of mercury. It is considered normal (760 mm Hg. Column) atmospheric pressure. The norm for a particular region may differ from other places. The atmosphere around us is a mobile shell in which changes occur daily. The adaptation of the human body to the conditions of a certain region and similar changes allows him not to feel them.
Those who have been to the mountains know that, having crossed the line more than 2.5 km up, an unprepared person for this area will feel oxygen starvation. It is accompanied by heart palpitations, a drop in blood pressure and other characteristic symptoms leading to general weakness of the body. Over time, after adaptation of the body, most of the ailments will disappear. If the process of change is slow, the human body gets used to it better.
People living in the mountains for a long time do not react painfully to the atmospheric pressure characteristic of these places. The norm for mountaineers is reduced environmental pressure.
This is due to the fact that their body developed at such atmospheric pressure, all its organs are acclimatized to such conditions. Pressure drops are not only in mountainous conditions and extreme situations, they are also possible in places of permanent residence of a person. The reason for such changes in atmospheric pressure is the air temperature. With an increase in its air mass, like all physical quantities, it heats up. The weight of a cubic meter of warm air is less than that of cold air, therefore, the pressure on the surface of the earth changes.
For people with poor health, especially for the elderly, pressure drops can be painful. In this case, you need to calm down and reduce physical activity. Even healthy people in such a period experience reduced working capacity, and sometimes a headache.
The human well-being is very affected by atmospheric pressure. Its norm can constantly change with a sharp movement of the air mass. Warm air, rising up, and cold air, falling down, lead to a difference in pressure in different layers of the atmosphere. According to this principle, weather is formed in a particular area. Its formation is also influenced by a number of points related to solar radiation, topography, air humidity, wind speed, etc. These factors are the basis for creating climate in this area.
Weather changes affect the human body in different ways. It is proved that almost every person reacts to them, only each in his own way. Meteosensitive people should know what the normal atmospheric pressure in their region is in order to know how to help their body in a difficult period. Weather reports report every morning which atmospheric pressure is the norm for the region and which prevails on that day. This is very important for people suffering from chronic diseases.
People with diseases of the cardiovascular and nervous systems are sensitive to changes in atmospheric pressure and very poorly tolerate weather changes. For them, the appearance of cyclones, which are usually accompanied by a decrease in pressure, worsening weather, strong winds and a decrease in oxygen in the atmosphere, is of great danger. At the same time, the temperature decreases, humidity increases, fog and precipitation appear. In this case, tachycardia, a drop in blood pressure and pulse are possible in meteo-dependent people.
