From a scientific point of view, when the temperature of the human body is lower than the temperature of the body itself, it will help the human body naturally improve the vitality of metabolic function, help improve the human body's physique, wear less clothes and exercise more, and enhance the body's resistance to changes in temperature. Highly recommended, hehe!

Of course, if you are weak, put on more clothes and exercise properly. It is best to add some red dates to drink more porridge in winter.

For those of us who have worked in the office for a long time, we should put on more clothes. Sometimes it's really cold without turning on the air conditioner. Don't get sick from freezing.
