Suitable temperature and humidity for human body are about indoor temperature 18℃, relative humidity is between 30% and 40%, and indoor and outdoor temperature difference is generally between 5 ~ 10℃, which is the most suitable temperature for human body. When the temperature in the environment begins to rise and is higher than 32℃, the body begins to have fever symptoms, and the body's mood fluctuates, making it easy to be agitated, anxious and tired. At the same time, when the indoor and outdoor temperature is too high, it will also affect the body temperature regulation center, and the body temperature will rise due to poor heat dissipation.

Hazards of humid environment

Humid environment will have many effects on the body, such as being more susceptible to infection by microorganisms such as fungi and bacteria, and inducing various skin diseases and rheumatism. However, these effects are not absolute and depend on the humidity of the environment and the state of the body. First of all, the humid environment is very suitable for the reproduction of microorganisms such as bacteria and fungi, so it may increase the risk of infection. Secondly, because the humid environment is not conducive to the discharge of human sweat, sweat can not be discharged, it is easy to suffer from various skin diseases.
