That is the atmospheric pressure, we are told at school at lessons of natural history and geography.We are familiar with this information safely and throw it out of my head, believing that he would never be able to use it.
But after years of stress and environmental conditions will have on the environment have sufficient impact.And the concept of "geozavisimost" no longer seem nonsense, t. To. The pressure shocks and headache will poison the life.At this point, we have to remember what the rate of atmospheric pressure, in Moscow, for example, to adapt to new conditions.And live.
School basics
atmosphere that surrounded our planet, unfortunately, quite literally presses on all living and nonliving.To determine this phenomenon there is the term - atmospheric pressure.This is the power of the impact of the air column of the area.In the SI system we are talking about 1 kg per square centimeter.Normal atmospheric pressure (for Moscow has long been known for optimum performance) effect on the human body with the same force as the weight and the weight of 1,033 kg.But most of us do not notice it.The body fluids of dissolved gases is sufficient to neutralize all the discomfort.
Standards atmospheric pressure in different regions are different.But the ideal is regarded as 760 mm Hg.Art.Experiments with mercury were the most significant in a time when scientists proved that air has weight.Mercury barometers - the most common devices to determine the pressure.It should be remembered that the ideal conditions for which the relevant named 760 mm Hg.Art., - a temperature of 0 ° C and the 45th parallel.
In the international system of units adopted to determine the pressure in Pascals.But for us familiar and intuitive use of the vibrations of mercury.
Features relief
Of course, the value of the atmospheric pressure is affected by many factors.The most significant are topography and proximity to the magnetic poles of the planet.Normal air pressure in Moscow, is fundamentally different from that of the same St. Petersburg;and only for the residents of a remote village in the mountains, this figure may seem abnormal at all.Already at 1 km above the sea level pressure is lowered.This corresponds to 734 mm Hg.Art.
As already noted, in the region of the Earth's poles amplitude of pressure changes is considerably higher than in the equatorial zone.Even during the day atmospheric pressure changes somewhat.Slightly, though only 1-2 mm.This is due to the difference of day and night temperatures.At night usually cooler and therefore higher pressure.
pressure and people
For a man, in fact, no matter what the atmospheric pressure: normal, low and high.This definition is quite conditional.People tend to get used to everything and to adapt.Much more important is the dynamics and magnitude of changes in atmospheric pressure.On the territory of the CIS countries, particularly in Russia, a lot of areas of low pressure.Often locals do not know about it.
Norma atmospheric pressure in Moscow, for example, could be regarded as unstable quantity.After all, every skyscraper - a kind of a mountain, and the higher and faster climb up (to go down), the more noticeable will drop.Some people may well lose consciousness, a ride on the express elevator.
Adaptation
doctors almost unanimously agree that the question "what is normal atmospheric pressure" (Moscow this or any location of the planet - does not matter) is not correct itself.Our bodies are perfectly adapted to life above or below sea level.And if the pressure does not have any damaging effects on the person, it can be considered normal for the area.Doctors say that the rate of atmospheric pressure in Moscow and other major cities in the range of 750 to 765 mm Hg.column.
Quite another thing - the pressure drop.If, within a few hours it rises (falls) by 5-6 mm, people begin to feel discomfort and pain.This is especially dangerous for the heart.His heartbeat quickens, and the change in frequency of breaths leads to a change in the rhythm of oxygen supply to the body.The most common ailments in this situation - fatigue, nausea, headache and so on. N.
meteodependent
normal atmospheric pressure for Moscow can seem a nightmare the visitor from the North or from the Urals.After all, every region has its own rate and, accordingly, their understanding of the stable state of the organism.And as in life, we do not focus on the exact terms of pressure, weather forecasters always emphasize that what this pressure for a given region - high or low.
It is not everyone can boast that they did not notice the relevant changes.Anyone who can not call yourself lucky in this matter, should organize their feelings during pressure changes and to find appropriate control measures.Often enough cups of strong coffee or tea, but sometimes more serious and require assistance in the form of medicines.
pressure in the metropolis
meteodependent most are urban dwellers.This is where a person experiences a lot of stress, living life at a fast pace and experiencing the deterioration of the environment.Therefore, to know what the rate of atmospheric pressure for Moscow - is vital.
capital of Russia located on the Upland, and this means that there are a priori low pressure zone.Why is that?It's very simple: the higher the altitude, the lower the atmospheric pressure.For example, on the banks of the Moscow River, this figure will be 168 m. A maximum value recorded in the city in Teply Stan - 255 m above sea level.
It can be assumed that the Muscovites expect abnormally low atmospheric pressure is much less likely than residents of other regions, which, of course, they can not be good.And yet, what pressure is the norm in Moscow?Meteorologists say that usually it does not exceed the rate 748 mm Hg.column.It does not mean much, t. To. We already know that even a rapid rise in the elevator may have on the human heart a significant impact.
On the other hand, Muscovites do not feel inconvenience, if the pressure is in the range 745-755 mm Hg.Art.
Danger
But from the perspective of physicians is not so optimistic for the inhabitants of the metropolis.Many experts rightly believe that, working on the upper floors of business centers, people expose themselves to danger.Indeed, apart from the fact that they live in the reduced pressure zone, they have almost a third of the day and held in place with thin air.
If we add the fact of violation of the ventilation system of the building and continued the air conditioner, it becomes obvious that the staff of these offices are the most unworkable sleepy and sick.
Results
Actually, it is worth remembering a few moments.Firstly, there is no single ideal value of the normal atmospheric pressure.There are regional standards, which can vary significantly in absolute terms.Secondly, especially the human body makes it easy to experience the pressure drops in the event that it occurs fairly slowly.Third, the more healthy way of life we lead and the more we are able to observe the regime of the day (the rise in the same time, a long night's sleep, the observance of elementary diet and so on. N.), The less we are exposed meteozavisimosti.So, more energetic and cheerful.
