Numbness or tingling in the hands occurs when nerves in the arm or wrist are compressed or damaged, according to WebMD. One of the simplest causes for nerve compression during sleep is when the arm is bent for a prolonged time or rested underneath another part of the body.
Another cause of tingly numb feeling fingers is an overly stressed body. Since stress causes the bodyâs muscles and arteries to tighten, an overly stressed body can cause blood flow to be restricted to the hands, which can also cause a numb and tingly feeling in the fingers.
