Why Do My Arms Fall Asleep When I Sleep On My Side
Olivia Luz
It may happen if you ve lain on your arm or otherwise put pressure on it.
Most of the time the cause is simple. This prevents the blood from flowing correctly to your nerves. Often a person s position is the cause. For example the arm may fall asleep because a person is lying in a way that puts pressure.
Awakening with numb arms is typically due to a temporary compression. If your arm or hand is in a position where pressure is applied to a nerve for a length of time it will gradually fall asleep. Most people experience occasional brief episodes of paresthesia. It can also cause your hands or fingers to become swollen.
