Exercise is accompanied by sweating, giving people the illusion that sweating is the result of fat burning! In fact, sweat comes from water in the body, not fat burning. If you feel lighter after sweating a lot, it is not that you have lost fat, but that you have lost the weight of water in your body. In the process of losing weight, we have a misunderstanding that the more you sweat, the better the weight loss effect will be, but it is not, because there is no inevitable relationship between the two. Sweating during exercise is a metabolic mode of human body during exercise, and only the water discharged from the body, not the oil, flows out.

First of all, we should know why the highway overpass sweats. People's life activities are carried out at a suitable temperature. Too high or too low temperature will hinder the metabolism of human tissues and cells and affect human health. Under normal circumstances, people's body temperature remains relatively constant, generally around 37℃. This is because the human body has the structure and function of regulating body temperature, which can make the human body emit heat while generating heat, and sweat glands all over the body act as this part of the function. During exercise, muscles in all parts of the body continue to work intensively, metabolism is enhanced, heat production in the body is increased, and body temperature is also increased. The body is intelligent. In order to keep the body temperature constant, the central nervous system and body fluid regulation began to move, and the heat dissipation began to increase gradually. At this time, the blood vessels of the skin relax, the blood volume flowing through the blood vessels of the skin increases correspondingly, and the secretion function of sweat glands is also strengthened, thus secreting a lot of sweat. The body takes away the temperature through the evaporation of sweat, thus emitting a lot of heat, so that the body temperature will not rise again, thus maintaining the normal metabolism of the human body. So does sweating evaluate the training effect?

Fat is the heat stored in the body, and the only way to burn fat is to keep yourself in a state of insufficient heat. Sweating is not equal to reducing fat. Some people will say that fat burning will not produce water and carbon dioxide. You see, sweat is also water. When fat burns, doesn't water just turn into sweat and be excreted? In fact, fat is composed of hydrocarbons and oxygen, so in fact, fat does produce water and carbon dioxide after burning, but in these two metabolites, carbon dioxide accounts for more than 80%, so sweating during exercise has little to do with fat. On the contrary, if you sweat too much, you are likely to get dehydrated. In fact, you can never cheat your body. What you really need to pay attention to is the consumption of heat, which is the heat deficit. Whether you can get enough calories in one day to reduce body fat and keep it.

Cognitive dehydration

For fitness enthusiasts, sweating will be much more than ordinary people. When sweating, we should replenish the lost electrolyte in time, because water and electrolyte are closely related to our sports performance and body function. According to scientific research, every percentage point drop in water in our body will lead to a 20% drop in sports performance. If you want to exercise and lose fat, you must replenish water in time. Electrolyte is a mineral, which helps to regulate water, blood pH and nerve function in sweat.
