How can I stop clenching my hands when I sleep?

Avoid laying on your arms under your pillow, which can compress nerves. Make sure your wrists remain unflexed, since flexing can lead to tingling. If you often sleep on your back with your arms overhead, try keeping them next to you to reduce nerve pinching. Try stretching your hands and wrists before going to sleep.
