Common Causes

Sleeping Position

Lying on your arm, wrist, or shoulder can compress nerves or restrict blood flow.

Sleeping with your arms above your head or tucked under your body often triggers numbness.

Nerve Compression

Carpal tunnel syndrome: Pressure on the median nerve in the wrist causes numbness, tingling, or pain, especially at night.

Ulnar nerve entrapment: Pressure on the nerve running through the elbow (funny bone area) can cause numbness in the ring and pinky fingers.

Cervical spine issues: Herniated discs or arthritis in the neck can pinch nerves, leading to numbness in arms/hands while lying down.

Circulation Problems

Restricted blood flow (from certain sleeping positions or underlying vascular issues) may cause temporary numbness.
