What can be used to keep from developing sweaty hands while rock climbing?

To prevent sweaty hands while rock climbing, climbers can use chalk, which absorbs moisture and enhances grip. Anti-sweat products, like antiperspirants specifically designed for hands, can also be effective. Additionally, wearing climbing gloves may help reduce sweat and improve grip, while frequent breaks to wipe hands can keep them dry during climbs. Staying hydrated and managing stress can also minimize sweating.
