Why do i sweat so much?
Sweating is a good thing, so I wouldn't be overly concerned. Yes it can be perhaps unsightly, and embarrassing, but its the main way your body has to cool itself. An interesting note, not sweating is an indication of perhaps a previous heat related injury (heat exhaustion, stroke etc). People who sweat excessively may have a condition called hyperhidrosis. You may look into it, but it doesn't sound like your case (I think its more for people who sweat excessively while inactive)
