Introduction: In cold winter, if you only wear thick clothes and don't do anything else, the metabolic rate of the body will decrease over a long period of time, and the organ work will slow down, making you depressed throughout the winter. Therefore, we must keep fit in winter. Through physical exercise, muscle contraction and enhanced human blood circulation, we can supply sufficient blood to all parts of the body, accelerate the metabolic rate, and generate more heat, so that the body will not shrink like that again. It can also provide more nutrients to the brain and improve memory. The summary is that winter fitness is of great benefit to both body and mind.
