Because we must first understand why we sweat when running. Simply put, it is heat dissipation. In a quiet state, when the ambient temperature reaches about 30 degrees Celsius, the human body begins to sweat. If the air humidity is high, the temperature of 25 degrees Celsius will cause sweating. During exercise, because the body produces a lot of heat and the temperature rises, the amount of sweating for heat dissipation often increases sharply.
The discharge of sweat mainly has the function of regulating body temperature and also discharges some metabolic wastes. So normal sweating is beneficial to human health. However, excessive sweating may lead to dehydration, resulting in dizziness, abdominal pain and other symptoms. In addition, the process of sweating is mainly to dispel excess heat in the body. A state of water loss caused by excessive sweating can only temporarily reduce weight. The real weight loss should be to reduce fat, exercise properly every day and consume a certain amount of calories in order to achieve effective weight loss.
In addition, excessive sweating can also lead to heatstroke. Don't wrap your stomach with plastic wrap to make it sweat like some stars, or wear airtight sweat-wicking clothes to exercise in summer. In fact, trying to sweat through sultry heat is a very wrong behavior, which will bring you bad symptoms.
