“Falling asleep” (Paresthesia) is the numb, tingling feeling you get when nerves or blood flow are temporarily compressed—like lying on your arm or sitting too long in one position.
It’s usually caused by:
- Nerve pressure → blocks signals to the brain
- Reduced circulation → less oxygen to the area
This leads to numbness and “pins and needles.” When you move, pressure is relieved, blood flow returns, and the tingling happens as nerves “wake up.”
Most cases are harmless and go away quickly. But frequent or long-lasting symptoms can be linked to conditions like Carpal Tunnel Syndrome, Diabetes, or Multiple Sclerosis.
Prevention: move often, avoid tight clothing, keep good posture, and take breaks from sitting.
