Who is at greater risk during exercise the more they sweat?

Some people think that sweating a lot during exercise will make the workout more effective.

However, sweating does not actually enhance the effects of exercise.

In fact, if a person with a certain condition sweats excessively, it can be dangerous.

 

◇Sweat, role in releasing moisture and lowering body temperature

Sweating a lot does not necessarily mean that the exercise is more effective.

Sweat helps lower body temperature by releasing moisture when exercise raises the body's temperature.

The more you sweat, the more waste and body fluids are lost, but it is not enough to significantly enhance the effects of dieting.

Although weight may temporarily decrease after sweating a lot, drinking plenty of water will bring it back to normal.

It's not fat burning, but rather water loss. Moreover, even with the same exercise, the amount of sweat varies from person to person, and the weight loss effect depends more on the type and intensity of exercise and the calorie expenditure rather than sweating.

 

◇ The risk of dehydration may actually increase

Excessive sweating can actually cause side effects.

Intense sweating during exercise can put strain not only on the musculoskeletal system such as joints but also on the heart and blood vessels.

Furthermore, sweating excessively lowers sodium and electrolyte levels, leading to dehydration and reduced exercise efficiency.

Losing 3-4% of body weight in water decreases physical activity levels, reducing long-distance aerobic exercise capacity by 20-30%.

When sweat loss reaches 5-6% of body weight, temperature regulation becomes difficult, and both pulse and respiration rates increase.

People with high blood pressure or impaired cardiopulmonary function are also at risk of fainting due to dehydration symptoms.

 

It is especially dangerous to exercise while wearing a sweat suit in order to sweat more.

Sweat suits create an environment similar to exercising in hot and humid weather.

Therefore, the use of fat is reduced and the use of carbohydrates is increased.

Lactic acid within the generated muscles is not easily expelled, leading to a quick feeling of fatigue.

If sweat does not evaporate and body temperature rises rapidly, it can lead to death from heat shock.

 

◇During moderate-intensity exercise, you should frequently drink water.

Therefore, it is good to do moderate-intensity exercise that causes a moderate amount of sweating during workouts.

It is also important to drink 120 to 150 mL of water every 10 to 15 minutes during exercise.

Additionally, when exercising, ventilation is better than sweat suits.

It is recommended to wear lightweight functional sportswear that works well.

It is good to do warm-up exercises before aerobic exercise and to do cool-down exercises for about 5 to 10 minutes after exercise to sufficiently cool down and sweat.
