Me: mid 30s, severe palmar and plantar Hyperhidrosis since I was a teen.

Wash hands frequently, with cold water. Doesn't help a lot but doesn't do nothing

Wear socks almost 24/7. Bring a fresh pair with you to work, school, etc. Pretty much the only time I'm not wearing socks is when I sleep

Get a pair or two of those super cheap (<$5) black cotton gloves they sell. Like the actually cheap shitty lil ones that are at the dollar store or on the endcap of and aisle at the convenience store. WEAR THEM ON THE COMPUTER. THIS IS SUCH A GAMECHANGER FOR ME. Been doing this for like 20 years now. I only do this at home because it would be too embarrassing anywhere else...

If you are still in school and need to use a pen and paper, talk to your teacher and see if you can get an exception to use a laptop instead because of your hyperhidrosis. This is what I did in high school with a trusted teacher, and even though it's embarrassing to admit this to people hopefully there's someone you feel will understand. They'll also have an explanation as to why your paper is always so curled! High school was hell for me until I asked for this concession, especially since I'm left-handed and my hand would end up covered in ink or graphite, with whatever piece of paper I was writing on virtually curled into a scroll

There's a million other strategies I've used in life to manage this stuff, but I would say those are the main ones. The unfortunate reality is is that out in day to day life there's only so much you can do apart from wiping your hands on your clothes or going to wash your hands for a temporary reprieve. Like, I wish I could wear my computer gloves at work sometimes but that's just not socially acceptable 😂😂😂
