Reduce the numbness in your hands at night by sleeping in a wrist splint, according to Mayo Clinic. This approach works best if your numb hands are caused by carpal tunnel syndrome, in which the numbness worsens at night. The American Academy of Orthopaedic Surgeons also recommends keeping your elbows straight while you sleep to reduce hand numbness at night.
Wearing a wrist splint while you sleep is effective at reducing nocturnal symptoms of tingling and numbness in the hands, states Mayo Clinic. If you are bothered by numbness of the hands at night, it is important to begin treatment with a splint as soon as possible before the condition worsens and more drastic measures such as surgical intervention are needed.
Sleeping on bent elbows at night can compress the nerves in the hands, causing numbness. The American Academy of Orthopaedic Surgeons suggests loosely wrapping a towel around your arm and fastening it with tape or wearing a backwards elbow pad to prevent your elbow from bending while you sleep.
To successfully treat hand numbness that happens at night, it is necessary to make sure the cause is properly diagnosed, notes WebMD. However, making lifestyle changes such as exercising more, improving your diet and taking vitamin supplements can contribute toward reducing numbness in the hands at night even prior to receiving a proper diagnosis.
