Can you lose weight by sweating during exercise?

　　Many people believe that the more you sweat during exercise, the better the effect. In fact, it is unscientific to say that sweating during exercise will help you lose weight. In fact, a large amount of sweat will take away potassium ions, sodium ions, salt and other substances from the human body. For people with poor physical fitness, excessive sweating may cause dehydration of the human body, resulting in dizziness, dizziness, stomach ache and other symptoms. In addition to poor physical fitness, you also sweat profusely when doing non-sweat activities such as walking and Tai Chi, so you should go Hospital Check whether you may have rheumatism.

　　It is understood that there are about 3 million sweat glands distributed in the human body. One end of it is the secretory part, which secretes sweat; the other end is the excretory part, which opens directly into the skin surface, called sweat pores. The discharge of sweat regulates body temperature and also discharges some metabolic waste. Under normal circumstances, sweating is a reflex activity, and the secretion of sweat glands can be caused by thermal stimulation or mental stress. When heat causes blood vessels to dilate, the water in the blood transfers heat to the surface of the skin, and then evaporates with sweat, transferring the heat to the surrounding environment. In high-temperature environments, the amount of sweat produced by the human body can be as high as 8-12 liters per day.

　　Of course some disease It can also cause the body to sweat. If you suffer from rheumatism or tuberculosis, you will sweat a lot. The sequelae of encephalitis are often accompanied by sweating. If this happens, you should go to the hospital for relevant examinations in time. “There is not much basis for the view that "sweating all over will help you lose weight", because the process of sweating is mainly to dissipate excess heat from the body. A large amount of sweating causes the human body to lose water, which can only temporarily reduce weight. Real weight loss should reduce fat, perform appropriate exercises every day, and consume a certain amount of calories, so as to achieve effective weight loss.

　　Things you need to pay attention to when sweating during exercise

　　Don't take a shower immediately after working out and sweating. Just after exercise, the human body is still in a state of strong metabolism and dilated blood vessels in the skin. If you take a bath immediately at this time, the skin will be irritated and pass nerve The reflection causes the blood vessels in the skin to constrict, which makes it difficult to dissipate heat and increase body temperature. At the same time, the blood flow to the skin decreases and the amount of blood returned to the heart increases, increasing the burden on the heart. Since sweat contains a lot of sodium chloride, if you sweat a lot, you should supplement your diet with salt and calcium. Therefore, in summer, you should drink some salt water appropriately after exercise, and then rest for about an hour before taking a bath. Of course, it is best to take a bath with warm water.
