Because the human head is the location of the brain’s nerve center. The head is the meeting of all suns. Although the skin on the head is thin, the blood vessels and hairs are thick and thick. Therefore, the body heat often evaporates from the head. Relevant research data show that when the temperature is around 15C, about 1/3 of the body’s heat is emitted from the head; when the temperature is around 4C, about 1/2 of the body’s heat is emitted from the head; and when the temperature is around minus 10C, there will be 3/4 of the body’s heat runs away from the head. It can be seen that the thermal balance between the head and the human body has a great relationship. If a person only wears a few more clothes without wearing a hat, it is like hot water without a plug, and the heat will be continuously exported.
Wearing a hat in the cold winter not only keeps you warm, but also avoids diseases such as cold, cough, headache, facial nerve palsy (ie, distorted mouth and eyes).
One is the aesthetic function.
If you buy a beautiful and fashionable hat, there is a dialect that says gimmicks, gimmicks, and gimmicks are on your head. The head can be beautified by the hat!
The second is conducive to keeping warm.
The human head also needs to be warm (easy to dissipate heat), and a hat is needed to keep warm. The material of the winter hat can be woolen yarn, woolen cloth, or a down jacket. Anyway, the texture should be thicker to keep warm.
The third is conducive to health care.
If you catch a cold, it will inevitably cause cerebral vasoconstriction, and you will feel dizzy and headache in the slightest, and accidents will occur in the worst.
The fourth is the protective function.
A cap on the head, in case of a slight scratch, the cap can cushion it. If there is a falling object, there is a hat to block it.
