What effect does humidity have on the body?

Humidity is a physical quantity indicating the degree of atmospheric dryness.

At a certain temperature, the less water vapor in a certain volume of air, the drier the air; The more water vapor, the wetter the air. In this sense, it is often expressed by physical quantities such as absolute humidity, relative humidity, relative humidity, mixing ratio, saturation deficit and dew point.

What effect does humidity have on the body?

Generally speaking, the effects of high air humidity on human body include abnormal function of thermoregulation center, abnormal adrenal hormone content, skin allergy, gastrointestinal discomfort and so on.

1, when the moisture content in the air reaches 40~60%, the human body is comfortable, but when the moisture content in the air exceeds 80%, it means that the humidity is too high, which will seriously affect the evaporation and heat dissipation mechanism of the human body and lead to the dysfunction of the body temperature center, which will lead to rapid rise or fall of the body temperature, rapid heartbeat, dizziness, nausea and vomiting, and prone to gastroenteritis and dysentery.

2. Excessive humidity will stimulate human pineal gland to metabolize pineal hormone, leading to decreased secretion of thyroid hormone and adrenal hormone, which will easily lead to fatigue and physical discomfort.

3, all kinds of bacteria, fungi and other pathogens like high humidity environment, which will accelerate their growth and reproduction. People who are allergic will have symptoms such as eczema and diarrhea due to these bacteria and fungi because their physique is too sensitive. In severe cases, it can also cause dehydration and shock.

4. In high humidity environment, it is easy to pollute water and food because of the accelerated growth and reproduction of bacteria.

5. If the humidity and temperature are high, the human body will have symptoms such as dry mouth, dizziness, chest tightness and fatigue, dizziness and tinnitus. If the body temperature continues to rise, it may lead to dehydration and even death.

6. If the humidity is high and the temperature is low, it will make the body more vulnerable to cold damage and increase the risk of diseases such as colds, rheumatism and arthritis.

7. Cold and humid environment may aggravate tuberculosis, cardiovascular and cerebrovascular diseases, chronic low back pain and other diseases.
