Does Sweating Burn Calories? – Credihealth Blog


As human beings, we are bound to sweat. It is the body’s natural method of temperature regulation. Sweat comprises water and salt, which evaporates to keep you cool. The human skin has sweat glands or sebaceous glands which facilitate sweating. Intensive physical activity, nervousness, and eating spicy foods cause you to sweat. But is it true? Does sweating burn calories? Let’s find out in this blog.

What is sweat made of?

Sweating or perspiration is the process by which we sweat. Sweat is 99% water. The rest 1% includes traces of salt, fat, sugar, urea, and ammonia

Why do we sweat after exercise? 

Sweating is most common after intense physical activity. As your body temperature rises, your hypothalamus (in the brain) signals to your sweat glands (located all over the body) to begin cool-down by producing sweat. Soon, beads of sweat start depositing on your body. Some of your sweat evaporates off your skin, leading to a cooling effect. You begin to cool down as your extra body heat is utilized to turn sweat beads into vapor. This is because sweating relies on a “heat of evaporation.” As you lose water in this process, it is very important to hydrate yourself by drinking plenty of fluids to prevent dehydration.

Why do you sweat when you are nervous?

Sweating when you are nervous is normal. A new job, responsibility, or relationship makes us nervous, causing intense sweating. This is called emotional sweating. 

This is due to the fight-and-flight response, not the conventional cooling sweat! Adrenaline, as well as other stress hormones, are released during the fight-and-flight reaction. 

This causes your heart and respiratory rates and blood flow to increase. Eventually, your muscles get tensed, which prepares your body for action. 

The released adrenaline rushes to activate your sweat glands in the armpits and groin, resulting in sweat secretion. The sweat reacts with the bacteria in your armpits; on the other hand, it swiftly metabolizes its nutrition and releases stinky by-products.

Why do you sweat while eating spicy foods?

A few bites of spicy food quickly numbs your mouth. Your forehead starts to sweat like anything, but why? Spicy foods contain loads of capsaicin which interacts with the temperature-sensitive nerves in your mouth. Although you know your mouth isn’t on fire, your brain is misled into believing you are overheated. That’s why you will probably start sweating profusely soon. This process is called gustatory sweating. Moreover, metabolizing large meals can also raise your body temperature, leading to light sweating or meat sweats.

What will happen if you never sweat?

If your body becomes too hot, whether from the external environmental temperature, fever, physical activity, etc., and there is no mechanism to control it, you will get a heat stroke! Sweating is considered gross, but is it gross if it saves your life?!

What are the benefits of sweating?

The main benefit of sweating is the regulation of body temperature. More benefits of sweating are:

  • Maintains healthy skin
  • Promotes good sleep
  • Detoxifies blood
  • Cleanses bacteria
  • Improves mood
  • Lowers risk of illness like kidney stones, cold, etc.
  • Boosts energy 
  • Boosts endorphins

Why do some people sweat more?

The amount of sweat you produce depends on genetics, age, weight, fitness level, and environmental factors. Your weight and fitness level have the greatest impact on how much you sweat during physical activity. The better your state, the faster you’ll sweat. It is due to the body becoming more efficient at temperature regulation. Heavy-weight people need more energy to function. It causes more sweating since there is more body mass to cool.

Does sweating burn calories?

Sweating does not burn calories by itself. Sweating indicates that your body has lost water, not fat. Physical exercise burns calories in general. The more vigorously you engage major muscles, the more calories your body uses, and the more heat and sweat your body releases.

But how many calories does sweating burn? Some people believe sweaty activities like Bikram yoga can burn up to 1,000 calories per hour. It is most likely inaccurate because studies indicate something else. A study conducted on men and women performing Bikram yoga found that women burnt an average of 330 calories in a 90-minute Bikram yoga class, while men burned 460 calories. Ironically, it’s the same as walking at 3.5 miles per hour for 90 minutes. This means you can burn calories while doing tasks that do not make you sweat much. You can still burn calories in winter by swimming, lifting weights, or exercising. On the other hand, sweating may be a useful indicator of your level of intensity. The harder you work out, the more likely you will sweat heavily. 

Risks of excessive sweating

Excess of something is said to be bad. The same is the case with sweating. While sweating is essential for your body, excessive sweating is unhealthy. 

  • Excessive sweating can result from heat exhaustion, over-exertion, and fluid loss. Sweating is essential as it maintains the body temperature, but excessive sweating can lead to dizziness, nausea, and severe dehydration. 
  • Dehydration due to excessive perspiration can also contribute to reduced performance, cognition, and impaired sleep quality. As a result, staying hydrated is crucial. 
  • Drink two glasses of water to replenish one pound of weight lost during a workout.

How do you burn calories safely?

The best method to safely reach your weight loss goals is to eat a balanced diet full of whole grains, carbohydrates, proteins, fibers, water, vitamins, and minerals. To lose weight, you must burn more calories than you ingest. At the same time, exercise regularly for at least thirty minutes. Therefore, adopting an active lifestyle is the greatest method of achieving a healthy weight. 

Conclusion – 

Sweating is essential for proper body functioning, but excessive sweating is unhealthy.  Not only does it regulate the internal body temperature, but it also eliminates toxins. But does sweating burn calories? NO. Sweating does not burn calories; physical exercise does.
