This phenomenon is normal, but sometimes it may affect our work and study.

In winter, in order to resist the cold, our bodies will automatically close sweat holes. In spring, sweat holes will open, and many people may find that they can spend the cold in winter, but they are a little uncomfortable with warm and cold spring. Pores relax and blood flow on the body surface increases, so the blood supply to the brain is relatively reduced. In addition, the metabolism is gradually vigorous in spring, and the body's oxygen consumption increases, which also causes the brain's oxygen supply to be relatively insufficient.
