Hot Index:
The heat index is the true temperature that the human body feels in high temperature and humid conditions. When the human body is in a high temperature environment, the body will automatically adjust to make the human body reach a more comfortable temperature. One mechanism of heat dissipation of the human body is sweating, which consumes heat during the evaporation process of sweat, so the purpose of sweating is to promote Evaporate and then consume the heat of our body. Make us feel cool.
When the temperature is high and the humidity is low, the sweat discharged from the human body will soon be evaporated; on the contrary, in the case of high temperature and high humidity, the evaporation rate of human sweat is much slower, when the temperature is kept due to humidity. If the body rises or the body does not evaporate for a long time, there will be cramps, heat exhaustion and even heat stroke.
