Why Do My Fingers Go Numb When I Sleep?

Finger numbness during sleep typically occurs when prolonged pressure compresses nerves or restricts blood circulation. The most common cause is sleeping in positions that put sustained pressure on your arms, hands, or wrists, leading to temporary nerve compression. Carpal tunnel syndrome affects up to 10% of adults and frequently causes nighttime numbness due to median nerve compression at the wrist. Other factors include ulnar nerve compression at the elbow, cervical spine issues, or conditions like diabetes and hypothyroidism. The numbness usually resolves within minutes of changing position and restoring normal blood flow. If numbness persists regularly or is accompanied by pain, weakness, or tingling that continues after waking, consult a healthcare provider to rule out underlying nerve disorders or circulation problems.
