ELI5: If sweating is such a vital function; why is antiperspirant not considered harmful?
gpt
Antiperspirant doesn't prevent you from *all* sweating. If it did, you would almost certainly overheat and become very sick.

It prevents *some* sweating, specifically in areas that typically are used less for cooling off and more for odor production (eg armpits).
