Judging from the number of antiperspirants on the market, one might think sweating is a bad thing, but it’s actually quite beneficial for your health.
Secreted through pores in the skin, sweat is composed of 99% water. It also contains minerals, urea, lactic acid, sugar and ammonia—which accounts for the odor as sweat dries.
Although you don’t even notice it happening, your pores widen or narrow depending on changes in your body’s core temperature. This is your body’s way of regulating its temperature.
When the human body’s temperature increases, it “blows off steam” by secreting sweat. That’s how the temperature is brought to normal, preventing overheating.
For every gram of sweat we produce, one liter of blood is being cooled down by about one degree Fahrenheit. Sweating also helps the body get rid of toxins and wastes. Its mineral content explains why sweat tastes salty.
Sweating can bring many other benefits to your health , too. When you work out to the point of sweating, your heart pumps more rapidly. This improves blood circulation and increases your metabolism.
Sweat also assists in loss of excess weight, as your body uses up a lot of energy to produce sweat, burning calories in the process at a rate of roughly 300 per hour.
As the sweat is secreted, it helps cleanse the body, not just from the inside but the outside as well, as dirt and impurities on the surface of the skin can be cleansed away through sweating. Proper sweating and skincare can help keep skin looking youthful.
There are also other ways of stimulating sweat besides exercise, such as saunas and steam baths . Such facilities have been used for thousands of years in many cultures.
Although saunas and steam rooms are intended primarily for relaxing and unwinding, there’s a side benefit of sweating out toxins. Additionally, in a dry sauna, the body creates a fever reaction that increases the production of white blood cells, thus making the immune system stronger.
Approximately a quart of water can be lost during a twenty-minute sauna session. That’s why it is important to hydrate before, during and after sauna use. The object, after all, is to improve health, not to end up dry as a bone.
