What should I do if my hand slips while playing basketball?

On the one hand, playing in cement for a long time will attach a lot of dust to the ball. If you play for a long time, the sweat and dust on your hands will dry, which will reduce the friction between your hands and the ball. If possible, you can dip some magnesium powder in your palm before you lose the ball, or grind some chalk dust yourself to reduce the sweat on your palm, or clean the court before you play. Playing indoors rarely leads to hand slip, and sweating on the palms can make catching the ball more secure!
