Air pressure is created by the continuous movement of air masses.As part of the atmospheric environmental conditions, it has a direct influence on human health and well-being.

Air pressure is the compression, i.e. the compression of air.
Changes in air pressure are caused by various complex atmospheric processes, to which the heating of air masses by solar radiation makes the largest contribution. Furthermore, the rotation of the earth has a decisive influence. Air pressure also decreases measurably with increasing altitude above sea level.
At sea level, a mean air pressure of 101325 Pa (Pascal) is assumed. This standard value can also be given as 1 bar.
Researchers assume that air pressure fluctuations with an amplitude between 0.3 and 0.5 hPa have an effect on blood pressure, circulation and concentration.
Protective measures under labour law apply with regard to negative or positive pressure. If the value falls below the standard value, a person is exposed to negative pressure. If the value falls below 0.73 hPa, the type and duration of the activity must be adjusted for health reasons.
Overpressure can result in health restrictions even at a pressure increase of 0.1 hPa above the standard value. Therefore, workers under 18 years of age and over 50 years of age may not be employed under these conditions, or may only be employed with special permission. Pregnant women, nursing mothers and people with acute or chronic illnesses are also prohibited from working at overpressure. At an overpressure of more than 3.6 hPa, work can only be carried out with a state exemption.
Air pressure is not responsible for health and well-being alone, but as a part of the atmospheric environmental conditions. In this context, scientists distinguish between three levels of physiological and psychological weather influences.
All people fall at least into the category of "weather-responsive", i.e. they are in a better mood when the temperature is pleasant and the sun is shining than when it is raining and cold.
Those people whose nervous system reacts to fluctuations in air pressure and temperatures are considered "weather-sensitive". This reduces the general stimulus threshold, while the perception of pain is increased. Typical symptoms are headaches, tiredness, sluggishness, fatigue, concentration and sleep disorders.
One speaks of "weather-sensitive" when changes in the weather aggravate existing illnesses or old injuries (e.g. broken bones) cause renewed pain. This is especially true for patients with chronic diseases of the respiratory or cardiovascular system, ateriosclerosis or rheumatism. People suffering from chronic pain, migraine or allergies also often experience a worsening of their symptoms when the weather changes. In addition, mental illnesses can worsen in this context.
Furthermore, it should be noted that with increasing pressure, the gases contained in the air (especially nitrogen) are increasingly absorbed in the body.
Air pressure is created because the air - driven by the Earth's gravity - wants to flow towards the centre of the Earth, but is stopped by the Earth's surface.
Changes in air pressure result from the constant movement of air masses in the atmosphere. A high-pressure area is said to exist when colder air masses push over warmer ones, thereby increasing the pressure of the lower air masses. The air warmed by the higher pressure expands and escapes. To replace it, air from the higher layers flows in and warms up.
When warm air masses rise and disperse in the atmosphere, the air pressure on the ground decreases and a low pressure area is formed. The formation of a low-pressure area is often accompanied by a strong onset of pressure, which can lead to health problems in people who are sensitive to the weather and weather conditions.
The air pressure in the air-Q is measured by a high-precision, high-resolution sensor. This scans the air pressure over 30 times per second. This means that the sensor is even able to detect the minimal changes in air pressure that occur when windows and doors are opened and closed.
The air-Q air analyser can measure air pressure in real time and comprehensively analyse indoor air and air quality by measuring a total of 14 substances and substance groups(pollutants such as carbon monoxide). The device can be ordered here.
