Will You Burn More Calories When You Sweat More?

While you are exercising, have you ever wonder whether you are burning more calories if you sweat a lot? Read on to find out more.

When our body temperature increases, we will sweat to cool off.

Here are the truth behind sweating and calories burnt:

  • How much you sweat will not influence on how many calories you burn. What is important is how long and how intense you have been working out. How much you sweat also depends on the air temperature, humidity, gender (man sweats more than woman) and genetics too. If it is hot and humid, you may still sweat just by walking outside.
  • The actual reason hot yoga is conducted is not to make you sweat more and therefore burning more calories, but to provide a warmer environment so that your muscles are more flexible to stretch and to pose. Of course, if burning calories is also one of the benefits of hot yoga, no one will say no.
  • If you experience an immediate weight loss after your workout, it is most likely water loss. You gain it right back after you rehydrate yourself by drinking water. Athletes such as boxers who need to lose a few extra pounds before weighing their weight will put a sweat suit on to run to lose that excess weight. That weight they lose through sweating is purely water weight. The same happens to people who lose weight via steam bath or sauna.

In short, sweating and burning fat has no direct correlation. So, do not try to jog under hot weather or wear heavy clothes to exercise hoping to sweat more. The notion that wearing sweaters translates into better fitness is probably a misguided scene from all those “Rocky” movies. You may overheat yourself and suffer from heatstroke. You do not have to sweat to get a good workout.

    This is what I believed. But my friends think otherwise. They equate more sweat to more burn. Granted that you will feel good after a sweaty workout, I believe one that just makes you break out in light sweat is just as beneficial too.

    Pretty interesting answer, but sweating def means you need to stay hydrated during your workout. Lack of water can slow down your workout and your results.

    In my early days as a teen, we used to think that if we were drenched in sweat, we are burning lots of calories. It means you need to rehydrate and not necessarily that you are burning more than the person next to you barely breaking a sweat.

    Well, if breakin into loads of sweat means more calories burn then the world would be filled with ppl lookin like fitness models, obesity wouldnt be a problem anymore – 50% of the population in the world would have 6 packs and stuffs. Personal trainers would be out of jobs LOL

    Notice how some men (with unflattering physique) hogs the sauna and steam bath – just gotta let them know it doesnt work that way. Generally, ppl are still too obsessed with scale weight.

    wearing sweater while working out works well in country with 4 seasons especially during winter time. it is just too cold outside to properly warm yourself up or to keep the temperature up while performing your workout but somehow doing that in a tropical weather country such as us will only make us look stupid if not give us heatstroke.

    however sometimes it is ok to wear so during your workout session in the gym. sometimes it is just too cold in the gym especially during rainy season. cold muscles equals to poor performance if not unwanted injuries.

    I can’t tell you how many people feel that profuse sweating equates to a great workout……….either that or if they are really tired at the end of the workout it means it must have burned a lot of fat off.

    Great article! I know so many people who think that sweating is an indicator for weight loss. Some even take the “next” step and don’t drink during a hard workout.

    Great blog btw. Thanks for sharing your knowledge and experience. It’s definitely useful for the general public.

    Cheers

    Thanks for the great post. I agree with you that many people believe that the more one sweats, the more one loses weight. The reality is that you can lose weight only when you burn off more calories than what you consume.
