I find that when I drink or eat something hot, I start to sweat. If I keep myself cool in front of a fan or air conditioner, I am okay, but without these, the sweat just dribbles down my back, my scalp is wet, sweat goes into my eyes, etc. I am 65 year old, and went through menopause quite some time ago. I have had blood tests done, and it is not my thyroid, but my sugar came back elevated. I was in Hong Kong for three weeks prior to Christmas, and the humidity was so bad that I was suffering from heat stress the whole time I was there. I have not been able to cope with any humidity whatsoever since.
