During winter exercise and fitness, due to the continuous contraction of muscles, accelerated breathing, accelerated blood circulation and vigorous metabolism, the heat generated by the body increases, and at the same time, the excitability of the cerebral cortex is enhanced, making the thermoregulation center sensitive, accurately regulating body temperature, improving people's ability to keep out the cold and increasing the oxygen supply to the brain. Therefore, people who keep fit in winter will play a positive role in eliminating fatigue caused by long-term brain study, enhancing memory and improving learning efficiency.
As the saying goes, "move more in winter and get sick less;" What is the reason for lazy drinking a bowl of medicine in winter?
