Question

Why does sweat from a workout sting my eyes, but sweat from a sauna does not?

In: Biology

Answer 1

During a workout your muscles become acidic, the acid is washed off by your blood and goes to your urine and sweat so the sweat becomes slightly acidic too and that burns your eyes.

In the sauna there’s no acidic change and you just sweat neutral acidity.
