Sweating is a natural response when feeling hot or exercising, but some may experience excessive sweating, which can become bothersome. As temperatures continue to rise during summer months, it's crucial to stay hydrated and avoid prolonged sun exposure. However, this does not mean we should avoid sweating at all costs. Experts reveal that this bodily function actually has positive effects on our skin and bodies.
**Sweat Prevents Our Bodies from Getting Overheated**
The primary reason we sweat is to regulate body temperature. Melanie Palm, a dermatologist and founder of Art of Skin MD in San Diego, states, "Sweat plays an important role in effectively cooling our bodies." This occurs through the secretion of sweat from sweat glands onto the skin's surface, leading to evaporation that helps reduce internal body temperature.
**It Eliminates Toxins from the Body**
Research shows that sweat glands help our skin filter toxins from the body, such as alcohol, which in turn boosts our immune system. A 2016 study indicated that those committed to vigorous exercise to maintain fitness have lower levels of heavy metals in their bodies, such as mercury or lead. At high concentrations, these toxins can reduce energy levels and adversely affect organs.
**It Promotes Clear and Healthy Skin**
Sweat acts as a natural protection against germs and bacteria. When we sweat, the pores open up. A dermatologist explained that sweat encourages the pores to expel trapped oils and dirt, but to benefit from this, it's essential not to let the sweat dry, as this may cause dirt, oils, and bacteria to accumulate under the skin, leading to breakouts. Sweat also helps maintain skin health by increasing blood flow when combined with exercise. Effective circulation ensures that skin cells receive the nutrients and oxygen they need.
**It Aids in Weight Loss**
Sweating can accelerate the loss of water weight in the body, which is why boxers go into saunas before a match to speed up weight loss. Dr. Robert A. Hager, head of research, sports performance, and safety at the Korey Stringer Institute at the University of Connecticut, explains that while you technically lose weight from sweating, the change is only temporary: "It’s not fat mass, which is the weight most people aim to lose." Some evidence suggests that an individual who sweats during exercise is engaging in a more intense workout. Since your body is working hard, you are also using energy and burning calories, which is a sign of good cardiovascular health.
**It Reduces the Risk of Kidney Stones**
The sweat glands release water onto the surface of your skin; therefore, lower amounts of water in the body mean fewer times you'll want to use the bathroom. This translates to a reduced chance of having substances that cause kidney stones in the kidneys and urinary tract. Conversely, we drink more water when we sweat, which means flushing these minerals from our system.
