In winter, the human body is affected by low temperature. Under the regulation of the central nervous system, skin blood vessels and sweat glands will contract, reducing heat dissipation.
In spring, as the temperature rises, the skin blood vessels stretch, the blood supply to the body surface will increase, and the blood and oxygen supplied to the brain will decrease accordingly, and the excitability of the cerebral cortex will be affected to some extent; Moreover, in spring, the days are long and the nights are short, so people's sleep is relatively reduced, so there is a phenomenon of "spring sleep".
In addition, from the perspective of traditional Chinese medicine, spring is the season when yang is produced. If the yang in the body is insufficient, it will be easily attacked by dampness, resulting in spleen-stomach imbalance, and there will be symptoms of listlessness and mental fatigue.
Many people use more sleep to solve the problem of spring sleep, but lying down for a long time hurts the gas, and sleeping too much will lead to poor blood circulation and uncomfortable meridians.
