Why Some People Wake Up with Tingling Hands: Common Possible Causes

Many people have experienced the strange sensation of waking up in the middle of the night with a numb arm or a tingling hand that seems temporarily “asleep.” Although the feeling can be surprising or even unsettling, it is usually short-lived and resolves within a few minutes after changing position.

This common experience is often described as “pins and needles,” but the medical term for the sensation is paresthesia. While temporary paresthesia is generally harmless, understanding why it happens—and recognizing when it may signal a more serious medical condition—is important for maintaining overall health.
