Why do your hands fall asleep while you sleep? Discover the truth behind this nocturnal phenomenon

4. Diabetic Neuropathy:

For people with diabetes or prediabetes, nighttime numbness can be an early warning sign.

5. Cervical Disc Problem:

A herniated disc in the neck might compress nerves running to the arms.

If tingling occurs with neck or shoulder pain, imaging or a specialist evaluation may be needed.

6. Poor Sleep Posture:

The simplest cause is how you sleep — lying on your stomach or putting your arm under a pillow can compress nerves.

Sleeping on your back with good neck support is better.

7. Multiple Sclerosis:

Although less common, MS can cause numbness with fatigue, balance problems, or vision changes.

Persistent numbness with other symptoms should be checked out.
