Three dog days refer to the three "dog days" in summer, namely, the first dog days, the middle dog days and the last dog days. During this period, the temperature is high and the humidity is high, making people sweat easily. Sweating on the back is also normal, because the skin on the back of the human body is thicker, sweat glands are densely distributed, and it is easy to sweat.
Sweating is a self regulating mechanism of the human body. Sweating can dissipate excess heat in the body and maintain body temperature balance. In the environment of high temperature and humidity, the human body needs more perspiration to dissipate heat, so the amount of perspiration will also increase.
In order to avoid problems such as dehydration and heat exhaustion caused by excessive sweating, it is recommended to drink more water in dog days and pay attention to replenishing water and electrolytes in the body. At the same time, wearing loose and breathable clothes, avoiding exposure to the sun and staying in air-conditioned rooms for a long time can also reduce sweating.
In a word, it is normal to burn your back and sweat in the dog days. You should pay attention to maintaining proper water intake and heat dissipation to avoid discomfort.
