Actually, the hot weather is not the direct cause of heat stroke. Heat stroke is mostly caused by sweating caused by heat. Under the high temperature in summer, the body sweats tens of times more than usual. In addition to taking away heat, so much sweat also takes away a lot of water in the body. Sweating is divided into active and passive. The so-called passive sweating refers to the formation of sweating due to the sultry weather and irritability. This sweating method is unfavorable to the human body. And a lot of sweating also takes away a lot of nutrients. If you don''t replenish water in time, it will produce dehydration symptoms.
