Really, sweating? Hmmm. I remember not sweating that easily when I was younger, like I felt like 'I don't sweat' but I do sweat not if I exercise or get really hot in the summer (some).
But I've always had this thing, and I don't know if this is tied to sweating or iodine, but since I was little I've had several episodes of a sort of heat exhaustion where I'd get so hot and my face would get so hot and really really pink and if it progressed I'd get a head ache that might last even into the next day. If bad enough I'd want to fall asleep. Even when I was a small child I'd get hot and pink in the face. In these incidents though, everyone else around me were all perfectly fine. I mean it would be hot but they'd be perfectly fine.
My dad always said it was like my skin didn't breath.
This is something I think I'll look into, thanks.
And the tyrosine too, I didn't hear of that before.
