normal atmospheric pressure

The air that surrounds our Earth directly has a fairly large mass, but it cannot be compared with the atmospheric mass of our planet Earth.

Our planet has a pressure of a million units more. Can you imagine? The enormous force with which the air mass presses on the globe is called atmospheric pressure. On absolutely every person of us, it presses a certain column of air currents of at least 20 tons. Yes, and it's not surprising! Man is not at all the main one on this planet, we are led by her majesty nature. If we delve into the topic in more detail, then we can say with confidence that this quite normal atmospheric pressure is capable of simply blowing everything into the sky with its power or easily crushing all living organisms on the planet. A counter question arises: Why then do we not feel it at all? You ask in surprise. And to explain this is quite simple: the internal normal atmospheric pressure is equal to the full atmospheric pressure of the outside world. And thanks to this, the influence of the two spheres is balanced, and in principle it may not be felt.

What is the unit of pressure?

Normal atmospheric air pressure is measured in mm Hg, and its unit is pascal. In order to measure the unit of pressure, a special device is used - BAROMETR (if you translate its meaning from Greek, the word means: BARO - heavy weight, METR - measure). Barometers come with a mercury base or no liquid.

Even a long time ago, people were completely confused by the unusual case that the fountains in which the water flowed so majestically and alluringly did not rise to a height of more than 10 meters. The king wanted to make a beautiful and not ordinary garden, with the greatness of many fountains aspiring upwards, but he could not do it. Various technologies, searches and experiments did not find a proper explanation for this. However, there was a man who showed the world what was happening and created a device that explains everything that happens.

E. TORRICHELLI in 1642 proved his theory: Air has its own mass. Unreal! - However, this is more than true. See for yourself!

E. TORRICHELLI soldered a long glass tube and filled it with mercury. Later, he lowered the glass tube into a cup filled with mercury. Mercury in the tube - significantly decreased to the level of 760 mm Hg, and poured into the cup. An immense void arose above the column of mercury mass, which was called the TORRICHELLI void.

TORRICHELLI in the series of this experiment was once again convinced of his conjectures. He believed that the influence of the majestic atmosphere on the plane of mercury and its mass in the cup was completely equal to the weight of the mercury column in the tube. And the upward length of this air column is 760 millimeters of mercury above sea level.

What atmospheric pressure is considered normal?

Usually, normal atmospheric pressure is considered to be the pressure that is at a height of 760 millimeters of mercury at a gradation temperature of zero degrees Celsius. As for qualified specialists, they agree 100% with this indicator of the norm, and answering the question: what is considered normal atmospheric pressure? They call the figure, the range of which is within 750 - 60 millimeters of mercury. Doctors say with full confidence that many people can easily get used to any condition and to a change in pressure. We really have nothing to do with different states, we can easily make an airplane flight from one zone to another. But, there are also people who can sit on the couch with a cup of tea and feel that the weather will soon change for better or worse. As a rule, this presentiment manifests itself in headaches, weakness that appeared suddenly and a person constantly has moisture on the palms. If you recognize yourself in the second case, it is recommended to immediately consult a doctor. After all, these signs can mean that you have problems against the background of the endocrine system and vascular disease in general.

As world statistics and various studies in this area show, normal atmospheric pressure for a person never stands still. Usually there is a sharp jump in the differential, either up or down. As a rule, normal atmospheric pressure changes instantly and in a short period of time. Scientists have proved that it is the representatives of the beautiful half of humanity who live in large settlements that react rather violently to changes in atmospheric units. Unfortunately, the fast rhythm and pace of life, the ecology of the 21st century and overpopulation are not the best parameters for the health of any person. If you recognize yourself in what you wrote, don't worry! From the dependence associated with an increase or decrease in pressure, you can easily get rid of! You just have to follow these rules:

1. Constantly harden your body.
2. Walk and run a certain mileage daily.
3. Follow a certain specialized diet. Avoid junk food.
4. You can save on anything, but don't save on your vacation. Sleep as much time as you want, and not as advised by unproven sources.
5. Do your best to get rid of bad habits. They are quite detrimental to your body and health in general.
6. If you suffer from problems associated with excess weight - do everything possible to lose those extra pounds as much as possible and get back to normal. Your well-being will reach a positive level and the general condition of the body will become stabilized.

How can the human body react to pressure that increases several times from the norm?

Answering the question: What atmospheric pressure is normal for a person's good condition and health, we already know a familiar figure. But, quite often there is a significant jump, and the pressure rises sharply. What's going on around? We may notice clear, beautiful (as it seems to us) weather, there will be no humidity at all and sudden changes in temperature. For a healthy person - an increase in pressure does not lead to anything special. But for hypertensive patients and people prone to all kinds of allergies, this is a signal of poor health. Can you imagine? If we talk about such weather conditions in the village, then in the weather without a single gust of wind, air with gases from the exhaust pipes of the car makes itself felt. The very first to feel a bad condition, people who have problems with the respiratory tract. Even if you do not have problems against the background of increased pressure, then remember that such a phenomenon significantly reduces immunity.

If you want to avoid all sorts of complications, then heed the advice of a leading specialist:

Always start your morning with a workout. Take a shower afterwards. For breakfast, eat foods high in potassium (for example: banana, dried apricots, raisins, and so on). Do not overeat and eat junk food at least in the morning. Do not waste strength on physical activity and show strong emotions. On the day when the pressure rises, go to bed earlier than usual.

How can the human body react to low blood pressure?

We have already learned, learned about his promotion. And what is the limit of low pressure? If you answer this question conditionally according to the barometer marks, then it will show us a figure below 750 degrees in millimeters of mercury. But, again, everything is purely individual and depends on the area of ​​\u200b\u200bresidence. For example, for Moscow, the norm of blood pressure is a mark of 748 millimeters of mercury. Again, an absolutely healthy person will not feel any significant difference, but for example, people who suffer from heart problems complain of a certain weakness of the body and feel shortness of breath, headache and lack of oxygen.

- Get your blood pressure back on track. Minimize your physical activity. Drink plenty of fluids and include green tea with honey in your diet. Drink a cup of aromatic coffee first thing in the morning. Take various herbs to strengthen the cardiovascular system. Take a shower in the evening after a hard day.

How do we react to sudden changes in air humidity?

In addition to the fact that atmospheric pressure can fluctuate, humidity can also fluctuate. Low humidity, which is almost half the required parameter, is completely unhealthy for our body. It seriously irritates the nasal mucosa, and the first to be exposed to this are people prone to allergies and people with asthma. The state of the body is reduced to a negative mark and this can cause an exacerbation of diseases of the kidneys and joints. The recommendations of doctors in this regard are reduced to the fact that:

If you have such an opportunity, then at least temporarily change your climate of residence to a drier one. Minimize your time outdoors in rainy and wet weather. Go outside only in warm clothes to prevent the body from catching a cold. Take daily the required portion of VITAMINIZED means.

Air temperature and pressure

As practice and various studies show, the most stable temperature for a person in a room is 18 degrees Celsius. Especially this parameter should be taken into account for the room where a person spends his rest. When the pressure decreases and the temperature rises, people with asthma and hypertension begin to feel bad.

Now you know what normal atmospheric pressure is for a person. But, imagine the pressure being the norm, the barometer shows in 3 cases out of 10. That is, very rarely. It can be concluded from this that a person is constantly in an uncomfortable position and condition for him. Of course, we have adapted to this inconvenience so much that many simply do not feel it. But, after all, most of them are significantly influenced by the atmosphere and feel uncomfortable while experiencing sharp pains. To avoid all sorts of consequences and unpleasant sensations, I would like to finally say: Follow all the recommendations of qualified specialists, their many years of experience will undoubtedly help you cope with the incredible power of nature and stop responding to temperature and pressure fluctuations.
