what would cause one to sweat excessively? i don't neccesarrily have to be in the gym or anything. i could just be simply walking down the street on an 75-80 degree day and sweat not too much but just enough where it's becoming to feel uncomfortable. i'm not over weight by any means. i'm fairly hydrated and the clothes i wear are loose ventilated. for example... i'm currently in boston now and it's about 78ish +/-. i'm just standing outside and i walk towards the garage and start sweating. this is getting out of hand. any ideas? thanks!
