Many experts believe that sweating is the body’s way of ridding itself of toxins, waste matter and other impurities.
This view is borne out by the fact that in ancient times Turkish baths and now steam and sauna baths are designed in a way that makes you sweat, in an effort to cleanse and purify not just your body but also your skin.
You may have noticed how after some vigorous activity of a workout, the skin flushes becomes warmer and seems to glow.
This is due to increased circulation and increased flow of blood to the extremities and the surface of the skin. It is this increased blood circulation that makes your skin acquire an attractive natural glow.
Sweating can also clear the pores of the skin and free them from sebum, which is excessive oil produced by the skin which can clog the pores and cause blackheads and even acne [blackhead removal]. This is the reason that many people find that their skin is brighter and clearer during summer when sweating is more common.
So in a variety of ways, sweating is good for the skin as long as you clean the skin soon after and do not allow the sweat to dry and cake upon the skin.
