The Science of Sweating: Why We Do It and How to Stay Fresh

Our bodies have between two and five million sweat glands distributed across the skin, forming a highly efficient cooling system.

Sweating plays a vital role in maintaining body temperature. Overheating can be dangerous, potentially causing heat stroke, extreme fatigue, dehydration, and even exhaustion. By producing sweat, the body cools itself naturally.

Sweating also helps the body eliminate toxins and heavy metals absorbed through food, air, and substances applied to the skin. Metals such as nickel, lead, arsenic, and copper are partially expelled through sweat, making this process an important part of detoxification.

Physical activity is the most effective way to remove heavy metals through sweat. Sweating in a sauna can also relieve pain, particularly in rheumatic conditions like arthritis, as well as headaches. Regular sauna use may improve memory and even help reduce the risk of Alzheimer’s disease.

Sweat naturally moisturizes the skin, enhancing its texture and elasticity. It contains compounds with natural antibiotic properties that help combat bacteria on the skin. However, if sweat lingers too long without washing, it can contribute to breakouts.

Certain factors can increase sweating. Blood sugar imbalances, even when lab tests appear normal, can lead to excess sweating, particularly when high-carb or processed foods are consumed. Overactive thyroid function is another common cause of excessive sweating.

Tips to help reduce excessive sweating:

Apple cider vinegar: Mix a tablespoon with a little honey in a glass of water and drink twice daily.

Sage infusions: Sage is a versatile plant that helps reduce sweating. Note: not recommended for nursing mothers.

Cooling herbs and foods: Mint, verbena, and chamomile have cooling properties. Foods with cooling energy such as cucumber, leafy greens, watermelon, and cool water are also beneficial.

Avoid stimulants and spicy foods: Coffee, tea, and other caffeinated drinks increase sweating as the body works to expel toxins. Spicy seasonings and fried foods also raise body temperature and promote sweating.

By understanding why we sweat and incorporating natural strategies to balance it, we can support our body’s cooling system, improve comfort, and maintain overall health.
