Why do people want to sleep so much in spring and always want to sleep? Is it related to the weather?

Maybe it was spring sleep. Spring fatigue

It is a response to the physiological changes brought about by seasonal changes. 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 also 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 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. However, it is worth noting that it also contains some pathological factors, and some "spring sleep" is the manifestation of the disease. For example: depressive symptoms before psychotic episode; Low fever and lethargy before hepatitis; Sleepiness caused by chronic causes such as diabetes and heart disease. Therefore, the "spring sleep" caused by the disease should be checked and diagnosed in hospital in time.
