number of weather-sensitive people is growing all the time.The height of the column of mercury is now predict how the day will be held, what kind of mood and well-being is a person.But initially it was thought that the atmospheric pressure only affects the weather.Let's see what the low and high atmospheric pressure, and whether it can be so much influence on our lives.
What is the atmospheric pressure
If we take the general definition, it is the value that shows the force with which a column of air presses, ranging from the top of the atmospheric layer, on land or water.
above 762 mm Hg - is vyskokoe atmospheric pressure and below 758 mm, respectively, low pressure.Fixed maximum pressure at sea level - 808.7 mm and the minimum - 684 mm.
What determines the atmospheric pressure
First of all, the pressure changes due to uneven heating of the air above the Earth's surface.Features landscape zones, the Earth's rotation, the difference in the heat capacity and the reflectivity of the earth's surface and water - all of this has an impact in this case.This produces cyclones Anticyclones which form weather.
Cyclones - this is a relatively fast-moving vortices with low atmospheric pressure.In summer, they bring rain and cool in winter - snow and thaw, but always - strong winds and overcast skies.
Anticyclones - a slow-moving area, which is characterized by high atmospheric pressure.In summer, they create a hot windless weather and in winter - the frosty and clear.
In planetary scale atmospheric pressure uniformly changes from the equator to the poles.The area of low pressure - a district of the equator and 60-65 degrees south and north latitude.And the high - 30-35 degrees latitude, and both poles.In addition, over the cold continents each winter there is a stable high atmospheric pressure.
Barometric pressure also changes depending on the time of day.Its peaks are accounted for 9-10 hours and 21-22 hours, and declines occur in 3-4 hours in the morning and 15-16 hours.
Effect of high atmospheric pressure being
Sudden changes in atmospheric pressure lead to the deterioration of health in weather-sensitive people.High atmospheric pressure can bring these symptoms:
- reduction in heart rate;
- lowering blood pressure;
- a rare and deep breathing;
- slight decrease in hearing and smell;
- muffled voice.
risk group with increasing atmospheric pressure
First of all, at risk get the elderly and chronically ill, suffering due to heart and vascular problems, unstable blood pressure.
They may be pain in the chest, jumps in blood pressure, worsening stenokradii, headache, tachycardia.
What will help with high atmospheric pressure
If forecasters are predicting the onset and increase pressure anticyclone, the weather-sensitive people should prepare in advance - to try to reduce physical exertion and to consult a doctor so that he appointed a special medicines.
high atmospheric pressure often leads to severe frost or prolonged heat.A temperature effect on health is several times stronger than the pressure.So better to keep yourself and try not to go once again to the street, while the apartment has to be a comfortable temperature.
In any case, no need to panic, not to get the effect of auto-suggestion.An interesting fact is that the people using elevators are subject to a change in atmospheric pressure several times a day, but their health does not suffer just because the elevator - a usual phenomenon.Take care of yourself!
