Sweating while playing any sport is almost inevitable. Suppose you are involved in playing high-intensity sports like badminton, tennis, cricket, etc., besides your entire body generating sweat. In that case, your palms are arguably the most affected part of the body with respect to getting sweaty. While sweaty palms are irritable, their adverse effects are more than what meets the eye. Once your palms get sweaty, it is not easy to have a firm grip on the sporting equipment you use to play the sport. For instance, in badminton, it is the badminton racquet; in tennis, it is the tennis racquet; in cricket, it is the cricket bat or ball, and the like. Sweat tends to intervene with your optimal performance. Therefore, keeping the sweat at bay, at least from your palms, is paramount.  

That said, if you suffer from sweaty palms, it may be hard to overcome completely. But there are several ways you can help keep it in check. Here are a few tips for you if you suffer from the problem of sweaty palms:

Regularly wash your hands 

Rinsing with clean water is fine unless your hands are dirty, as too much washing with soap will dry your skin. While playing the sport, ensure that you wash your hands after regular intervals of time.

Have a pack of tissues handy

Always carry a pack of tissues to wipe your hands during the game of play.

Carry hand gel in your pocket

If washing your hands at regular intervals is not possible, then ensure that you carry a pocket-size hand gel. The gel will help you cleanse and dry your hands.

Include talcum powder in your kit bag

Talcum powder is an elixir as far as keeping that irritable sweat away from your palms is concerned. It can absorb sweat and give your hands a better grip.
