What is the reason for sweating in summer?

High temperature in summer; Human sweating is closely related to environmental conditions such as temperature. Modern health care medicine divides human sweating into inconspicuous sweating and effective sweating. When the temperature is below 20 degrees Celsius, people who rest will sweat, but this kind of sweat is so small that the human body can't feel it, so it is called no sweat. When human activity or temperature is higher than 25 degrees Celsius, the proportion of not sweating is not large. In order to dissipate heat, the human body will dissipate heat by discharging and evaporating sweat, which is easy to feel, so it is called effective sweat. Therefore, sweating is an important function of the human body to regulate body temperature and keep it stable. It should be noted that the amount of sweat of healthy people is closely related to meteorological factors such as wind, humidity and air pressure besides temperature and activity. When the temperature is high and the humidity is low, the human body is most likely to sweat a lot; On the contrary, the wind speed is low, the humidity and air pressure are high, even if the temperature is high, the human body will sweat poorly. Under such circumstances, people are more prone to heatstroke.
