The main factor affecting the amount of perspiration is "temperature", including "outside temperature" and "body temperature (heat generated by physical activity)". When it's hot in summer, standing outside for a while will make you sweat. When the temperature is high, you can sweat a lot with low-intensity exercise. After all, the main function of perspiration is to regulate body temperature and keep it within the normal range.
During exercise, the metabolism of the human body is accelerated (the body generates heat) and the body temperature rises. Moderately raising body temperature is beneficial to exercise (which is why it is necessary to warm up), but overheating is not enough. If the body temperature is too high, the body will try to dissipate heat, or the body will "burn out". Sweating is the most important way to dissipate heat.
For example, just like a computer needs a fan to dissipate heat, if there is no fan to dissipate heat, playing a very large game (equivalent to your strenuous exercise) will basically burn out the motherboard. Generally speaking, the greater the intensity of exercise, the longer the duration of exercise, the more heat generated by the body and the more sweating, but this does not represent the exercise effect.
"Sweat is the cry of fat" is a positive slogan, but it is wrong from a scientific point of view. "How much sweat you have" does not mean "how much fat you have lost". Many people will say that I lost weight after exercising 1 hour. Isn't this weight consuming fat? That's not true ... most of the weight you lost is "water", and you can make up for it by replenishing water.
Others will say, isn't this the "moisture" produced by fat decomposition? Really not, your sweat is not directly produced by fat decomposition. So in the early years, there were many slimming belts in TV shopping. After putting it on, I sweated on my back, and then promoted that fat was "burned". This is silly. During exercise, I not only consume fat, but also consume other energy substances.
Secondly, people will sweat when they are nervous (mental sweating), and they will sweat when they eat spicy food (even some people will sweat a lot as long as they eat). Does this mean that your fat has been consumed? Therefore, the effect of reducing fat cannot be measured by the amount of perspiration. It takes a long time to measure the effect of reducing fat (for example, one month). (It's not bad to send a sweaty photo and show it off with friends ...)
