Is there such a thing as "spring sleepiness"?

Spring is warm, flowers are blooming, birds are chirping, and there is vitality everywhere. But many people often feel lazy in spring, especially in the afternoon, and they feel lethargic and drowsy. This is what people often call spring sleepiness.

Why do people suffer from spring sleepiness? It turns out that in order to resist the severe cold in winter, the peripheral blood vessels on the surface of the body are in a constricted state to reduce heat dissipation. This makes the blood supply to the internal organs and brain relatively sufficient, so people are full of energy. The temperature rises in spring, but the peripheral blood vessels have not yet adjusted and adapted, so spring sleepiness will occur.

At the same time, in spring, human metabolism increases, oxygen consumption increases, and the oxygen supply to the brain tissue decreases, which can also make people sleepy.
