是假的吧....
it is true that sweating is a mean of excretion
but i'm almost sure there is no toxin in the composition of sweat.
what so called "toxins" are actually products or waste of bacteria
exotoxins: metabolic products released by bacteria
endotoxins: cell wall components of bacteria, release when the bacteria lysis
in normal circumstances, there should not be any other bacteria exist except those of normal flora
secondly, the hair that are expose on the skin are already "dead". they are dead keratin cell. it doesn't really matter if you shave it or not
next time when you post such "informational" post, check if it's ture
