Why does your skin itch when we sweat?!
Question:
Why does your skin itch when we sweat?
Answers:
Sweat is salty. Salt water solutions when they evaporate can become highly concentrated and caustic. (Consider road salt.) As long as your skin is protected by natural oil you don't tend to itch but if that barrier is not there, as in dry skin, the salt can act as an irritant.
