Normal atmospheric pressure for a person - on what do the indicators depend?

Around our planet there is an atmosphere that presses on everything that is inside it: rocks, plants, people. Normal atmospheric pressure for a person is safe, but its changes can seriously affect your health and well-being. To avoid possible troubles, scientists of different specialties and study the impact of AD on a person.

Atmospheric pressure - what is it?

The planet is surrounded by an air mass, which, under the influence of gravity, exerts pressure on all objects on the Earth. The human body is no exception. That's what atmospheric pressure is, and if we talk in a more simple and understandable language: AD is the force with which air pressure is applied to the earth's surface. It can be measured in pascals, millimeters of mercury, atmospheres, millibars.

Atmospheric pressure under normal conditions

On the planet presses an air column weighing 15 tons. Logically, such a mass would have to crush all the living things that are on Earth. Why does not this happen? It's simple: the fact is that the pressure inside the body and the normal atmospheric pressure for a person are equal. That is, the forces outside and inside are balanced, and the person feels quite comfortable. This effect is achieved due to gases dissolving in the tissue fluids.

What is the normal atmospheric pressure? The ideal BP is usually considered 750-765 mm Hg. Art. These values ​​are considered correct for living conditions, but they are not true for all localities. On the planet there are zones of reduced - up to 740 mm Hg. Art. - and increased - up to 780 mm Hg. Art. - pressure. People living in them, adapt and do not feel any discomfort. In this case, the visitors immediately feel the difference and for a while will complain of malaise.

Norms of atmospheric pressure by region

For different points of the globe, the normal atmospheric pressure in mm of mercury is excellent. This is explained by the fact that the atmosphere affects the regions differently. The entire planet is divided into atmospheric belts and even within small areas the readings can differ by several units. True, not sharp changes are felt rarely and the body is perceived normally.

The normal atmospheric pressure for a person under the influence of various factors changes. It depends on the elevation of the terrain above sea level, average humidity and temperature. Over warm zones, for example, the compression of the atmosphere is not as strong as over cold ones. Strongly influenced by pressure is the height:

What atmospheric pressure is normal for a person?

Determine blood pressure in ideal conditions: clearly above sea level at a temperature of 15 degrees. What is the normal atmospheric pressure? There is no single fair indicator for all. What normal atmospheric pressure will be for one or the other person depends on the state of health, living conditions, hereditary factors. One can only truly say that the optimal blood pressure is one that does not cause harm and is not felt.

How does atmospheric pressure affect people?

Its impact is not felt by everyone, but this does not mean that the influence of atmospheric pressure on people is absent. Sharp swings, as a rule, make themselves felt. AD in the human body depends on the force of expulsion of blood from the heart and the resistance of blood vessels. Both indicators can fluctuate when cyclones and anticyclones change. The reaction of the body to pressure surges depends on what is the normal atmospheric pressure for this person. Hypotonics, for example, react poorly to low blood pressure, and hypertensive patients suffer from its even greater increase.

High atmospheric pressure - impact on humans

The anticyclone is characterized by dry, clear and windless weather. Elevated blood pressure is accompanied by a clear sky. Under these conditions, temperature fluctuations are not observed. The most severe reaction to hypertension is hypertension - especially the elderly, - people suffering from diseases of the cardiovascular system, and allergies. During anticyclones, cases of heart attacks, strokes, hypertensive crises are more often recorded in hospitals.

Understand that the pressure is increased, you can, knowing what normal atmospheric pressure is for a person. If the tonometer shows a value of 10-15-20 units greater than it, this blood pressure is already considered high. In addition, the increase in pressure is determined by such symptoms as:

How does people affect low atmospheric pressure

The first lowered blood pressure begin to feel cores and people suffering from intracranial pressure. They feel general weakness, malaise, complain of migraines, shortness of breath, lack of oxygen and sometimes pain in the intestine. The cyclone is accompanied by an increase in temperature and humidity. The organisms of hypotension respond to this by dilating the vessels with a decrease in their tone. Cages and tissues do not get enough oxygen.

Characteristic for reduced atmospheric pressure are also considered to be:

Meteozavisimost - how to deal with it?

This problem is complex and unpleasant, but you can cope with it.

How to deal with the meteorological dependence of hypotension:

  1. Healthy and lasting - at least 8 hours - sleep strengthens the immune system and makes it more resistant to BP changes.
  2. For vascular training, douches or regular contrast showers are suitable.
  3. Improve immunity helps immunomodulators and tonic.
  4. Do not put too much physical stress on the body.
  5. In the diet must necessarily include products containing beta-carotene and ascorbic acid.

Tips for hypertension are slightly different:

  1. In food, it is recommended to eat more vegetables and fruits, which contain potassium. Salts, liquids from the diet are best excluded.
  2. During the day, several times take a shower - light, contrast.
  3. Regularly measure pressure and, if necessary, take antihypertensive drugs
  4. In the period of elevated blood pressure, do not undertake difficult cases requiring high concentration of attention.
  5. Do not climb to a high altitude during the established anticyclone.
