Dizziness after fitness is the result of excessive exercise, which leads to hypoxia in the brain. Pay attention to the reasonable arrangement of exercise according to your own physique and physique. Remember not to drink cold water, blow air conditioner or take a bath immediately after fitness, so as not to cause pores to close and capillaries to be damaged, which may lead to a cold. You can use an electric fan to blow a little wind properly, and then add warm physiological saline or hot tea when the sweat is dry. If you really want to smoke, take a break before smoking, so as not to hurt the alveoli.
