Carpal tunnel: Any repetitive use of hands and wrist may cause swelling & compression of the 'median nerve' in the wrist causing 'the hand to fall sleep' . This 'pinched nerve syndrome' is called carpal tunnel. Wearing night splints may help, but you may need to get a nerve conduction study soon or you may have permanent damage.

Probably Carpal Tunn: Carpal tunnel syndrome is the most likely problem. Get it checked. You'll be happy you did.

Get eval: If carpal tunnel, you may benefit from a trial of splint/brace, nsaids, manipulation or non surgical intervention. Sometimes modification of work area w/ proper ergonomics helps relieve and prevent. Physical exam required. May benefit from nerve conduction study to confirm.
