Why is it that the whole body aches and fatigue is not easy to recover in spring?

Whole body aches and fatigue are a response to the physiological changes brought about by seasonal exchange. In the cold winter, the human body is affected and stimulated by low temperature, the capillaries of the skin contract, the blood flow is relatively reduced, the sweat glands and pores are closed, the heat dissipation is reduced, and the normal body temperature is maintained. After entering the spring, with the increase of temperature, human pores, sweat glands and blood vessels begin to relax, and skin blood circulation is also vigorous. So the blood supply to the brain will be relatively reduced. As the weather gets warmer, the metabolism is gradually vigorous, the oxygen consumption is increasing, and the oxygen supply to the brain is inevitably insufficient. Coupled with the benign stimulation of warm temperature, the brain is inhibited to some extent. So people will feel sleepy, feel sleepy, and always feel that they don't get enough sleep.
