What causes sweaty hands?

Basically, it’s down to our eccrine sweat glands. They’re concentrated in our hands, forehead and feet, and directly connected to our sympathetic nervous system.

So, whenever we’re stressed, nervous or excited, that’s a cue for beads of sweat on our brow, along with clammy hands and feet.

For some people, the problem is more focused on the hands, and more severe. This condition is medically defined as palmar hyperhidrosis. It can occur from birth, but it’s more likely to start in adolescence.

For some, the problem will go away with age. For others, it’ll stick around all their lives.
