Thereof, why does my arm go numb when I sleep?
If your hand or arm gets numb, the cause could range from carpal tunnel syndrome to a pinched nerve. The most common reason for getting a numb hand or arm is sitting or sleeping in the same position for a long time. That can put pressure on your nerves and cut off blood flow, which brings on short-term numbness.
Subsequently, question is, can your arm die from sleeping on it? But don't worry: A few hours of nerve compression and decreased blood flow won't make your arm fall off. But if paresthesia continues over a period of days or weeks, it can lead to lasting damage. “For example, people who are paralyzed or who've lost sensory perception sometimes get bed sores,” Prinsloo said.
