Pressure Hg. Norma atmospheric pressure for a person in Pascals

The pressure (atmospheric) is a physical quantity expressing the force with which air under pressure to the mass of earth and all that is in it. For each region of mercury indicators are different, because they are influenced - altitude, humidity and temperature of air masses.

The human body adapts to the pressure in the living climate zone. If there is a change in the index up or down (moving to another area, change of weather, a trip to the mountain), the deviation from the norm can cause disruption of health.

What is air pressure?

Earth is surrounded by the atmosphere, which consists of several layers and perform safety functions (Protects against harmful radiation, it maintains the desired composition in the air, and also holds all living and non-living matter in the world by providing pressure).

To determine the atmospheric pressure value uses several units (mm Hg. Art., Pascali, millibars). The essence of these indicators is the display of the magnitude atmosphere pressure exerted on a certain area of ​​the surface. A person does not feel the atmospheric pressure (with normal values), since it is balanced by the liquid inside the body.

Norms of atmospheric pressure in different regions of Russia

Pressure Hg (rate is dependent on the climatic zone) varies from region where the measurement is performed index. Man adapts to the value, which is home to. Therefore, when a change of residence with other climatic conditions, often the deterioration of health.

Performance of atmospheric pressure in mm Hg. Art. in the major regions of Russia:

names of regions	The average values ​​over the year	The maximum deviation
Izhevsk	747	753
Leningrad	755	762
Moscow	748	755
Permian	745	751
Seaside	755	766
Rostov	741	748
Samara	753	760
Sverdlovsk	738	755
Tula	747	755
Tyumen	771	775
Chelyabinsk	741	756
Yaroslavl	736	758

Depending on the season, the pressure indicator can vary up or down.

The variability of the air pressure depending on the height of terrain and other conditions

influence of the main factors to consider when measuring the pressure indicator:

• height above sea level. When you are at a point of geography, but at different heights, pressure will vary in the following hand - at rise above the sea level pressure will decrease, and when lowering the to rise;
• temperature display. When the temperature is above 0 degree index atmospheric pressure will decrease. At temperatures below 0 degrees atmospheric pressure to rise;
• humidity. The increased liquid content in the air is a cause of increased pressure. In dry weather, the pressure indicator drops.

Therefore, in the summer during the night (when the temperature decreases and increases humidity) increases pressure indicator. The primary reason for changing indicators is the change in air density on the influence of these parameters.

Normal human for the column of air pressure in mm Hg and pascals

Pressure Hg (measured rate at sea level in Paris at an air temperature of 15 degrees) 760 mm Hg. Art. or 101.3 kPa is the standard normal indicator. But this value is relative when compared to its effect on the human condition. As the body adapts to the indicator, which is prevalent throughout the year in the region of human habitation.

Influence of atmospheric pressure variations on the people

The human body is arranged to measure pressure which prevails in the climatic zone. As a result, systems and organs are functioning normally.

But when the value of a restructuring in the body, which is accompanied by the following variations:

• Headaches in the temples, dizziness and fainting;
• quick breakdown;
• irritability due to headaches and fatigue;
• depression or anxiety no reason;
• respiratory deterioration (there is a lack of air);
• violation of the rhythm of heart contractions and pain in the heart;
• decrease / increase in blood pressure;
• blurred vision and "fly" in front of the eyes due to an increase in intraocular pressure;
• impairment of blood circulation, followed by numbness of extremities;
• pain in the joints. Caused by circulatory disturbance;
• Nausea and decreased appetite;
• noise and hum in his ears;
• disruption of the digestive tract;
• deterioration of attention;
• drowsiness.

Health deterioration is marked at atmospheric pressure drops of 5 units.

Daily fluctuations in the 1-2 division does not affect the functioning of the body. Changes develop as a result of violations of the fluid in the body, which leads to malfunction of systems and a slower metabolism. If these deviations occur in the body in humans even at small pressure change indicator and regularly, diagnosed meteozavisimost.

risk groups

The pressure (atmospheric) may cause a malfunction state, even in healthy people if indicator Hg risen or fallen by more than 3 bar for 1-3 hours. After returning to normal atmospheric pressure being stabilized.

Diagnosis meteozavisimost diagnosed more frequently in the following groups of people:

• men and elderly women. Their body can not quickly rebuild under atmospheric pressure;
• women during childbearing. During this period, the body's aimed at maintaining pregnancy and fetal development. As a result, pregnant women feel even small pressure differences;
• children up to 3-5 years. Their bodies are still just learning to react to weather changes;
• teenagers during hormone adjustment. In this period, not only the body is sensitive to pressure variations, the psycho-emotional balance is disturbed and weakened immune system;
• during menopause. Organism again passes hormonal changes and is sensitive to any changes inside and outside;
• People with kidney disease. The disease causes a disturbance of an aqueous composition in the body that cause an increased sensitivity to pressure variations;
• allergic and asthmatic. Meteozavisimost caused by decreased immunity;
• patients with diseases of the cardiovascular system and suffering from blood pressure fluctuations;
• people with the presence of chronic pathologies of the musculoskeletal system;
• Patients with psychological disorders;
• people with chronic ENT diseases.

People living in large cities with poor environmental conditions are more prone to feel the pressure drops than people in rural areas.

Symptoms of health violations

Pressure Hg (normal for each person individually) can be increased or decreased, which causes meteodependent people have different symptoms.

Description of the symptoms, depending on the change of pressure indicator:

When an anticyclone. Weather phenomenon characterized by a change of normal atmospheric pressure at elevated.	When cyclone occurs normal atmospheric pressure change to low.
Pain in the heart	There is a lack of oxygen, shortness of breath and accompanied by emission of red blood cells (blood clots form dangerous phenomenon)
Increased heart rate	The number of heart rate quickens, but reduced the force of impact
Severe headache with the feeling the pulse in my temples, dizziness	Headaches can be unbearable nature
Fatigue and malaise	Rapid fatigue and general weakness (feeling of "padded feet")
Rush of blood to the face, causing the sensation of heat and redness	Deterioration in the quality of
The increase in blood pressure, may be accompanied by bleeding from the nose	Noise and a sense of buzz in the ears
Reducing the number of leukocytes in the blood, it is dangerous to colds and other infectious diseases or exacerbation of chronic pathologies	Aggravation of articular diseases and numbness
increase in sweating	lowering blood pressure
The sensation of ringing in the ears	Intracranial hypertension
Loss of field of view	Disruption of the gastrointestinal tract, accompanied by flatulence
Violation of the bowel (constipation)	The appearance of limb edema

When the pressure change in any direction occurs aggravation of chronic pathologies.

Health Hazards

atmospheric pressure change of dangerous weather-sensitive people, as well as his sharp change (rapid immersion in, climb the mountains, or a sharp increase / decrease pressure) for ordinary people.

Possible complications from atmospheric pressure fluctuations:

• violation in irreversible mental equilibrium direction (schizophrenia, depression, psychosis);
• development of stroke due to increased intracranial pressure;
• the development of a heart attack in people with heart disease;
• irreversible disturbance of mental activity due to lack of oxygen;
• the development of asthma as a result of violations of oxygen metabolism and activities of the bronchi;
• thrombus formation with the subsequent blockage of blood vessels;
• by reducing the risk of infection immunity by infection with the development of complications;
• deterioration of the blood vessel with a probability of development of varicose veins or gap;
• irreversible changes in the quality of vision and hearing. Possible to complete blindness and deafness.

Syncope also dangerous, as a result of incidence of loss of consciousness and can be fatal.

How to protect yourself from pressure surges meteodependent people?

Pressure Hg (normal rate can dramatically change to a higher or lower during the day several times) can not be adjusted, so people dependent on weather conditions, it is recommended to adhere to the following rules:

• be examined by a specialist. Medical examination will reveal additional causes the body's sensitivity to changes atmospheric pressure (latent chronic diseases, hormonal imbalance, or a general weakening immunity);
• to undergo treatment. To stop promptly exacerbation of chronic diseases in the care professional;
• weather forecasts tracking or purchase a home barometer. This method will advance to prepare for the approaching atmospheric pressure and to take preventive measures;
• ensure a good night's rest. Duration of night sleep to be at least 8 hours. It is also recommended to get up no later than 7:00 am and stay up to 10 hours. Restful sleep will allow your body to fully recover and move easily decrease / increase in pressure;
• to comply with a full power mode. Food must be diverse and contain sufficient amounts of vitamins and minerals. Good nutrition will strengthen the immune system and less responsive to fluctuations in atmospheric pressure. Also, from the menu to exclude heavy and junk food, do not overeat before going to bed and to avoid big breaks between food intake. This will prevent the development of pathologies in the gastrointestinal tract or exacerbation of chronic diseases, which contribute to a decrease in immunity;
• exercise daily walk in the open air (in any weather). Fresh air normalises metabolic processes in the body, it increases the amount of oxygen in the blood and strengthens the immune system;
• to make daily exercise. In the presence of the disease is limited physical activity a set of exercises is made in the office of physical therapy under the supervision of a specialist. Sport helps to normalize the activity of the cardiovascular system, blood circulation and strengthen the functioning of the joints. As a result, symptoms of fluctuations in atmospheric pressure will be less pronounced;
• adjust the order of the day. If there is a possibility that the duration of the cyclone or anticyclone to delay physical and mental work and devote more time to rest;
• in the morning to take a contrast shower. The procedure allows to normalize vascular condition, it activates metabolic processes and strengthens the immune system;
• eat vitamin complexes and immunomodulators. These drugs allow further strengthen the body's defense. It means especially recommended for busy people who do not have the ability to make daily walks, exercise and other methods to strengthen the immune system;
• to refuse from bad habits. Nicotine and alcohol have an adverse condition vessels, gastrointestinal organs and exacerbate the degradation of the period of atmospheric pressure differentials;
• taking medication. In the presence of chronic conditions necessary to prepare medicaments (ointments of joint pains, headaches tablets or means for lowering / raising the pressure). drug form depends on the type of disease, and are prescribed;
• taking sedatives. In the period of pressure fluctuations needed to take sedating medications and drink soothing herbal tea. They are involved in normalizing the blood pressure, eliminate nervous stress and help alleviate the symptoms of the differential pressure.

Additionally (in consultation with a physician) may acquire in advance the following medications prescribed for raising / lowering the atmospheric pressure.

when anticyclone	when cyclone
To eliminate the headache	Paracetamol	Painkillers and tonics	Kofetamin
analgene	askofen
ibuprofen	tsitramon
To normalize the activity of the nerve cells	Persen	To normalize the pressure	heptomino
Sedariston	apilak
novopassit	dopamine
For the normalization of the joints	Voltaren gel	To normalize the breathing	ketoprofen
Fastum gel	Intal
Nurofen gel	cromolyn

Taking medicines recommended to be combined with preventive measures, then atmospheric pressure will not affect the overall, even in weather-sensitive people.

Normal pressure indicator is considered to be 760 mm Hg. Art. But depending on the climatic zone value changes up or down. Man adapts to the indicator, which is prevalent in the region of residence. It is important that a sharp increase or decrease in mercury indicators is the main cause of sudden blood pressure drops.
