Answer: no, sweating is useless to lose weight!
Speaking of sweating, undershirts are very popular this year. Many stars are punching in the Weibo. It is said that wearing sweaty clothes sweats several kilograms at a time. A friend of mine in Wuhan also bought a set. Her weight is 1 15 kg, 165, belonging to the micro-fat world. Considering getting married and wearing a wedding dress in September this year, she is determined to lose 65433 a month. Every time he undresses, he washes his hair like a shampoo. Sweating. A week later, he has lost 2 pounds, which gives him the motivation to increase his exercise. He couldn't wait to wear sportswear for seven hours. As a result, he fainted just after wearing 1 day. According to the hospital analysis, it is collapse caused by severe dehydration, and even life-threatening if it is more serious. Let's not talk about the quality of this product, but I really want to say it.
What exactly is sweating?
Many people don't know that sweat glands are the most common in the human body. There are about 250 thousand sweat glands on the feet alone, and about 0.23 liters of sweat can be excreted every day. ……
What's in the sweat? Sweat is 99% water, followed by some salt, urea, minerals and so on. The human body is really like a sophisticated instrument. The function of sweat is to regulate body temperature. If you don't sweat, something will happen. When we exercise, the blood circulation is accelerated, and sweat can lower the body temperature after the body temperature rises; When it is cold, sweat glands and pores contract, thus stopping sweating and preventing body temperature loss. Sweating is just drainage, and fat will not be converted into sweat. Of course, some people say that I do lose weight after sweating every time I exercise. Admittedly, some people sweat after exercise and lose a few pounds, but when you drink some water and eat something, you are also called weight. Has it recovered?
Water is the source of life, and the human body is 70% water.
The human body is 70% made up of water, and there are more young people than old people. Newborn babies are 75% water, which is distributed in various tissues of human body, and the content of water is also different: the water distributed in bones and cartilage accounts for about10% of total bones; The moisture in fat accounts for about 20% ~ 35% of the total fat; The distribution of water in muscle has reached about 70% of the total muscle; In blood plasma, except for 6%~8% plasma protein, 0. 1% glucose and 0.9% inorganic salt, all other components are water, accounting for about 9 1%~92% of the total plasma.
What we really want to lose weight is fat. Sweating has nothing to do with fat. Some people say that they like the sourness of sweating, and even some people take plastic wrap to the sauna to sweat, but they don't know that such deliberate sweating may cause big problems!
Sweat too much, and collapse may find you!
Sweating more = losing water more. When you sweat too much and your body is seriously short of water, your body will naturally feel uncomfortable, dizzy and collapsed. Hypertonic dehydration is even more terrible. The loss of a large number of body fluids will harm other organs of the body: kidneys, central nervous system and so on. If you want to save your life, you have to take hormonal drugs.
Sweat too much, and infection may come to you!
Now I'm risking being beaten to tell you that wearing sweat-proof clothes for more than 40 minutes will make you sweat a few pounds more than exercise, and you won't run until you replenish water and dehydrate in time. Not only that, if you sweat too much, your skin will turn white, wrinkle and become fragile in a humid and closed environment. At this time, if you encounter some bacteria or fungi, you will be caught off guard.
Sweating too much, dermatitis may follow you!
Some people wrap their skin with plastic wrap and sweat. Some components in sweat may directly irritate the skin because they can't get out, and then contact dermatitis symptoms such as erythema and itching may appear.
Sweating more does not mean that the fat-reducing effect is good. Sweating only plays a role in regulating body temperature and discharging some metabolic wastes. How much sweat is normal? Generally speaking, as long as you are comfortable, it is normal to sweat more or less. Some people have developed sweat glands, so it is normal to sweat a little more, unless sweating is accompanied by fever, or at normal temperature, sweating is enough to make the bedding wet and must be replaced. In this case, it is necessary to consider that this may be the manifestation of some diseases and need to go to the hospital for further examination. On the contrary, some people will find that this is not very love sweating. For example, when people get older, the amount of perspiration decreases with age, which is normal.
Finally, friends who want to lose weight, don't blindly pursue a lot of sweating during the fitness process! After engaging in anaerobic exercise, the body will consume some calories in the body and burn some fat. When consumed to a certain extent, fat will be converted into energy and excreted! Everyone knows the importance of water to human body. Therefore, you must pay attention to hydration after sweating a lot. Supplementing more water will maintain the normal foundation of human metabolism and help to lose weight. Therefore, the most important thing to lose weight is scientific exercise!
