Hello, it is wrong to say that sweating helps to lose weight. People often see such scenes. People who jog in midsummer are all wearing a sweat-absorbing long-sleeved thick sportswear. These people want to lose weight. In fact, increasing sweating can only make your body lose water faster, so you may lose weight when weighing after exercise. However, if you replenish water after exercise, your weight will return to normal within one day, and the weight loss you see is only a temporary phenomenon. Sweating reduces the body's water, not fat, and water plays an important role in physiological functions. And this kind of weight loss may be dangerous, because the body mainly radiates heat through the skin. Wearing airtight sportswear, the body can't evaporate sweat and let the body heat stay in the body. The consequence of doing so in midsummer is easy dehydration and heatstroke fainting. Syncope is a temporary disturbance and loss of consciousness caused by various reasons. The danger of syncope also lies in accidents such as fractures and injuries caused by sudden fall of syncope. Dehydration makes people thirsty, reduce urine output, increase heart rate, reduce working ability and even lead to death. When running in shorts and a wide mesh vest, it is easier to emit body heat. So wear loose and generous clothes when exercising, and don't think about sweating more to lose weight.
