Why does our skin get injured more easily when we are sweating?


I have recently noticed that when I’m working out and sweating profusely, my skin gets injured easier: a random light scratch of my fingernail usually doesn’t leave any marks, but if I’m sweating a lot, it leaves a scratch mark that takes a few days to heal and hurts when I’m washing all those sweats off in the shower. Why does this happen?

In: Biology

This phenomena is likely due to you feeling less pain during physical exertion, so a “light scratch” when resting is far lighter than a “light scratch” when working out. In other words, when you’re working out, it takes a lot more force (and damage) before you notice a scratch at all.
