Sweating to lose weight: why as much as you sweat it does not mean that you will lose weight – POP TIMES UK

The idea that sweating a lot is equivalent to burning a lot of calories, and therefore losing weight, is deeply ingrained, but it has a problem: it is false, or at least, inaccurate. Sweating more does not mean losing more weight , and therefore many of the tricks that we can see in gyms, such as training with a lot of clothes on or wrapped in plastic garments are not only not effective, but they can also pose a certain risk.

Sweating is the mechanism that starts our body when its temperature rises too high . In an effort to maintain optimal body temperature (which may vary slightly depending on the person) the brain activates the sweat glands of our skin and these begin to release water with sugars, mineral salts and waste products generated in the breakdown of nutrients from food. When the moisture in your sweat evaporates, it takes some of the heat with it, thus lowering your body temperature.

Certain situations make us sweat more , for example if it is hot or humid, and not all of us sweat at the same rate, even under the same conditions. Taller and larger people tend to sweat more because they have more body mass to cool down, and people who are fitter tend to do so too, in their case because their cooling system has become more efficient to allow them to exercise for longer. .

Therefore, sweating more does not necessarily mean that you are burning more calories. Some people sweat more simply because of genetics, habit, or fitness level.

In reality, body fat does not burn or melt away . It is released by the body's fat cells to provide it with energy. Our body's metabolism breaks that fat down into two parts: fatty acids and glycerol. The more energy you need, the more fat the body asks from those cells.

This is the mechanism by which you actually lose body fat, which is different from what makes you sweat.

Of course, there is some relationship, albeit indirect. If you are exercising vigorously, you will probably break a sweat at some point because you are raising your body temperature. If sweating is the result of exertion, it is also a sign that you are using a lot of energy and therefore consuming fat from your body to obtain that energy.

But if you are using tricks to increase sweat such as training in a place where it is already hot, or wearing plastic garments that make it difficult for your body to release the excess heat, that does not mean that you are burning more calories.

Although fat and sweat are different mechanisms of the body, many people believe that sweating does indeed make you lose weight, and it is not really such a rare confusion. Probably if before and after a workout in which you sweat profusely you go through the scale, you will see that there is a significant decrease in your weight .

That's where the tricks to increase sweating come from : training in places where it is hot or sheltering a lot, putting on clothes that do not perspire (such as a raincoat) or even wrapping our abdomen in plastic film, spending a lot of time in saunas and Turkish baths

The problem is to think that this drop is due entirely to lost fat, because it is not. For the most part they are liquids , water that you have lost by sweating and that your body needs to recover later. When you've quenched your post-workout thirst, you'll find that your weight isn't that different than it was before your workout.

When we make efforts to sweat as much as possible during exercise, and we do not replace fluids to replace those we are losing, we can suffer dehydration that, depending on its severity, can have dangerous effects.

In milder cases , dehydration causes an intense feeling of thirst (this is how your body tells you that you need to drink water), as well as a headache and a mild feeling of dizziness. Usually it is solved simply by replenishing the fluids that we lack.

Severe dehydration has more serious effects. To begin with, life can become cloudy and an intense feeling of body fatigue and the need to sleep appear. This, coupled with a frequent urge to vomit can end up causing you to pass out or faint.

In the most severe cases of dehydration, hospitalization may end up being necessary, although this is actually more common when the cause is stomach diseases that prevent fluid retention. In the case of reckless behavior, it is advisable to replace the lost water simply by drinking, even if that means raising the figures on the scale a bit, which should never go down at the cost of our health .
