Does sweating really help you to lose weight?

06th November 2018

For decades, a large number of people have found use from sweat suits, garbage bags or saunas in order to lose weight quickly, but why do we put ourselves through this?!

Where does sweat come from?

Sweat is made in the sweat glands beneath the surface of the skin, and then it’s released out of tiny holes in the skin called pores.  The sweat takes the heat from the body when it evaporates.

Why do we sweat?

Sweating releases liquid from the body’s sweat glands which consist of salt. This process can also be recognised as perspiration. Sweating fundamentally helps your body to stay cool.

If I sweat less does it mean my work out is ineffective?

Sweating is the body’s cooling mechanism so it isn’t the most reliabe measurement of an effective workout, as nobody’s internal air functions are the same.

The amount you sweat depends a lot on your weight, gender, fitness level, age, where you live (climate) and even your genetics. For instance, an individual who has engaged in a low amount of physical activity can, in essence, sweat more than an individual who has engaged in a higher amount of physical activity.

Does sweating more mean sufficient weight loss?

You will lose weight in the form of sweat, constituting of water and electrolytes. Despite this, you will gain it back again as soon as you consume food or water! This myth seems to have circulated in the wrestling, boxing and fitness industry for years, encouraging individuals to feel the need to lose pounds in order to make a specific weight class.

The reality of this is that sweating actually has no useful purpose in weight loss. Weight loss after a workout can be explained by sweating contributing to water loss.

A true measurement of weight loss can be measured by the reduction of body fat which can be achieved by a combination of good nutrition and exercise.

What are the dangers of excessive sweating?

The dangers of excessive sweating can be life-threatening – the health effects that can be identified consist of overheating (heatstroke), extreme loss of electrolytes (kidney damage/death), and other cardiovascular related emergencies.

What’s the conclusion?

Sweating causes a loss of water weight, not weight loss, which is only temporary. Once you start consuming fluids and food again your weight will fluctuate back to the correct body weight.
