Sweating is a physiological function of human body to excrete and regulate body temperature, but if the way of sweating, the amount, color and smell of sweat change, it can be regarded as a precursor of some diseases and should be paid attention to.
Extended data
Sweat is the liquid secreted by sweat glands. Sweating due to thermal stimulation caused by the increase of external temperature or internal heat production is called perceptual sweating. At this time, the sweating area is widely distributed, and the skin in all parts of the body, especially the forehead, neck, trunk, waist, back of hand and forearm, is the most; Followed by the neck, trunk side and most limbs; Once again, the inner thigh and armpit; At least the palms and feet. Mental stress can also lead to sweating, and sweating centers are distributed in all parts of the central nervous system. Normal people unconsciously evaporate about 600 ~ 700 ml of water within 24 hours.
Sweating is divided into active and passive. Passive sweating refers to sweating due to sultry weather and irritability, which is harmful to human body. On the contrary, the sweat that the human body actively exercises is called active sweating, which is conducive to maintaining the temperature in the human body and emitting heat, which is beneficial to people's physical and mental health.
The function of sweat is to regulate body temperature. Think about it carefully, the human body is really like a precise machine. If you don't sweat, that's not good. Exercise, blood circulation is accelerated, body temperature rises and sweats, so that body temperature drops; When it is cold, sweat glands and pores will contract to prevent body temperature loss.
