Yes, as a matter of fact they do.
Don't worry if your hands get sweaty when your gaming, it happens to a lot of people and most of the time it's a perfectly normal reaction to intense action. Fortunately there are some things you can do to prevent sweaty hands. There are surgerys and medication available from a doctor. However, to many of us, this approach seems a little drastic. One other solution is to use a hand antiperspirant. It's a localized solution, it's temporary, and it works. Unfortunately hand antiperspirants aren't something you can usually pick up at your local grocery store and they differ widely. I would recommend one specifically for gamers. One designed to not leave buildup on your controller, one that's non-toxic and does not stain your clothes. I happen to be,, suprise, partial to GhostGrip.
Until next time, keep your hands dry and have a better experience gaming.
