Tennis and badminton players can use wrist bands to wipe the sweat off the forehead. This helps to improve vision. They also help to prevent sweat from flowing to the palms of the hand.
Wristband and Wrist wraps both are different items. The purpose of a wrist wrap is to provide support to the wrist joint during heavy or max effort lifts in pressing movements and overhead lifts. During these movements, the wrist can be pulled into excessive extension under load and result in compromised mechanics, possible injury, and failed lifts.
Similarly, Wristband for game and Wristband for Gym is also 2 different things. So, don't be confused in both of them.
