I work out five or six days a week, I'm in pretty good shape. I'm not overweight either. However I sweat profusely whenever I exercise, within a few minutes of starting, and the sweat just pours off my body. This has been going on for years.
All the information on hyperhidrosis I can find focuses on localized sweating in the armpits, not full body sweating like I experience. The only thing I can think of is that since I was born I can't breathe through my nose at all due to an anatomical issue. Could this be the cause of my sweating?
