Beginning of spring can take a bath and wash his hair on this day. He can wash his hair and take a bath every day. If he feels uncomfortable or wants to wash, he can wash. It is suggested that Zangquan should not take a bath for one hour.

It should be noted that it is not suitable for beginning of spring to have a haircut on this day, and it is unlucky for beginning of spring not to have a haircut. As the saying goes, hair is the vegetation of the human body, which is warm in spring and grows with vegetation, and the new vegetation is damaged, which is not in line with the principle of vegetation growth in heaven and earth.

In the process of metabolism, the human body always generates heat to maintain its body temperature. At the same time, heat is transferred to the body surface through blood circulation and continuously released to the outside world through radiation, conduction, convection and evaporation. People with strong physical resistance have normal thermoregulation function. Through adjustment, the two processes of heat production and heat dissipation are balanced, that is, when the body temperature tends to decrease, heat production increases and heat dissipation decreases, so that the body temperature is still maintained at about 37℃.
