In summer, you can always see sweaty runners in the streets and indoor gyms of the city. Most of them want to lose weight by running, but they have an inertial thinking. The more you sweat, the more you lose fat!

But this is a minefield for losing weight. I advise you to forget about this poisoned chicken soup.

Causes of sweating during exercise

The process of sweating is mainly to emit excess heat in the body, because during exercise, muscle activity will produce a lot of heat. When the body produces more heat than it emits, the body temperature will rise. In order to maintain normal body temperature, the body must increase sweat secretion to promote heat dissipation.

And how much you sweat during exercise varies from person to person, which is related to various factors:

1. Everyone's physical quality: People with strong physique have relatively healthy muscles and motor organs. Even if they exercise harder, they naturally have no strength and sweat less; On the contrary, people with poor health will sweat a little.

2. Body fluid content: There are many body fluids and sweating during exercise. The amount of body fluid is determined by the fat content in the body, because the water content in adipose tissue is relatively small, and fat people have less body fluid than thin people. Although fat people sweat more during exercise, their tolerance to water loss is relatively poor, so fat people will feel very tired after short-term exercise.

3. Whether drinking water before exercise also affects sweating. If you drink plenty of water before exercise, it will lead to an increase in body fluids and sweating.

Relationship between sweating and fat reduction

How much you sweat can't measure the effect of reducing fat.

You may have experienced extreme heat, excessive sweating or lost a few pounds after strenuous exercise. But that's because a lot of sweating causes the body to lose water and can only temporarily lose weight. As long as you replenish water in time, your weight will soon pick up.

At the end of 20 13, sports scientist RossEdgeley made a test. He lost weight 12 kg in one day by steaming in the sauna, running in sweaty clothes, taking diuretics and desalting on this day (electrolytes can help our body keep water).

Finally, he drank a lot of water containing electrolyte and quickly recovered his normal weight within a few days.

It can be seen that the weight loss caused by excessive sweating is only temporary, and more importantly, the figures on the weighing scale do not represent any problems. Losing weight is not equal to losing fat.

Theoretically speaking, in addition to providing energy, fat will be decomposed into carbon dioxide and water. This statement may give you a wrong understanding: after fat is decomposed, it is carbon dioxide and water, so discharging water is discharging fat.

But it's not just that. The decomposed water will basically enter the internal environment and participate in the life activities of the body, with little discharge. At the same time, carbon dioxide carries about 84% of the weight of fat molecules, while water is only about 16%. It is impossible to say that fat is directly decomposed into sweat and excreted to achieve the effect of losing weight.

The disadvantages of forcing the body to sweat

According to Ross's experimental method, it also debunked the popular rumor of losing weight in the market: a series of practices of forcing the body to "sweat" such as stovepipe with plastic wrap and wearing sweaty clothes have no effect of "losing weight" at all.

Wearing an airtight sweat-absorbent sweatshirt and sauna suit only consumes water to maintain the body's metabolism.

This kind of sweating in a short time will seriously dehydrate the body, cause electrolyte disorder in the body, lead to body temperature imbalance and neuroendocrine disorder, and even lead to chest tightness, shortness of breath, fainting and even organ failure, which is life-threatening.

Sweating can't detoxify

Even if I talk more, I still have a persistent partner, thinking that if I can't lose weight, sweating can at least detoxify.

Here Ma Niu wants to say that sweating is only a means of human metabolism and body temperature regulation, and has nothing to do with detoxification, fat reduction and beauty.

99% of the components in sweat are water, and other components less than 1% include metabolic wastes such as sodium, potassium, calcium, chlorine and urea nitrogen. The excretion of poisons in the body is mainly metabolized by the liver, filtered by the kidney and excreted with urine.

Moreover, we exercise and sweat, and our skin really gets better, because exercise promotes the body's metabolism and helps to detoxify, instead of sweating and detoxifying.

Exercise intensity determines the effect of reducing fat.

The effect of exercise on reducing fat is not necessarily related to the amount of sweating. In fact, exercise without sweating does not mean that it is invalid. What really determines the effect of reducing fat is the intensity of exercise, and what measures the intensity of exercise is the change of human heart rate.

For example, running, the same speed, the same duration, but in different seasons, the number of clothes worn and the amount of sweating are different, but the calories consumed by people and the effect of reducing fat are actually the same.

In order to lose fat, when we exercise, the heart rate, that is, the number of heartbeats per minute, must reach 75% of the maximum heart rate, generally 220 MINUS your age.

If you really want to burn fat, you still have to exercise, especially aerobic exercise. It is a continuous exercise of large muscle groups, with a maximum heart rate of 75%-80% and a duration of 45 -60 minutes. Oxygen, carbohydrates and water are used as fuels to oxidize fat.

So, don't torture yourself to sweat more!
