How do you deal with sweaty hands?

talc

I rub it into my shirt. You should google hand sweating problem. Maybe there will be a solution there.

talc never worked for me :(

Some people use an antiperspirant on their hands, one that contains aluminum chlorohydrate as the active ingredient.

There is a machine that uses a low-level electrical current called iontophoresis to “shock” your sweat glands in your hands into not working for a while. You can read about it here.

Some people use biofeedback or meditation to learn how to control the stress that can make hyperhidrosis start up.

Talc and baby powder aren’t a good idea because you end up with your hands caked with white stuff, so you can’t touch anything dark until you can get it all back off.
