Q: Why does Marco Rubio sweat so much?
Every few seconds he’s dabbing at his face with a hanky because the sweat is raining down by the gallons, down his face, into his eyes . . . does he get nervous or does he have a perspiration problem?
A: It could be a condition called ‘Hyperhidrosis’. Unfortunately, it doesn’t happen when a person is nervous, specifically. Individuals with this unfortunate condition can sweat profusely in a snowstorm much the same way anyone can sweat on a hot summer day. It’s mainly triggered by concentration when there are no other outliers.
They typically sweat while they are sleeping, after showers, and even while sitting in the shade on a cool day. They are their own personal oven since they perilously carry extra body heat, hence the sweating.
It isn’t curable and is unavoidable, and unfortunately, very embarrassing for the sufferer. h/t quora
Well now! That explains everything! Not.
