When Body Parts “Fall Asleep”?

The expression “falling asleep” refers to the uncomfortable feeling of numbness and tingling, often accompanied by a temporary loss of sensation or reduced movement in a body part.

 

The limbs—especially hands, arms, feet, and legs—are most commonly affected.

Paresthesia usually occurs when nerves are compressed or blocked for a certain period of time. This can happen when:

• You sleep with your hand under your head

• • You sit cross-legged for too long

  • You remain in the same position for an extended period
