When your hand or your foot falls asleep...my foot fell asleep and my muscle was like spazzing out...what exactly happens.?.?.?Health Question & Answer

Usually, you feel this familiar sensation after you've been putting pressure on part of you-r body -- sitting on a foot, sleeping on an arm, etc. When you apply this pressure for a prolonged period of time, you actually cut off communication from your brain to parts of your body.

The pressure squeezes nerve pathways so that the nerves can't transmit electrochemical impulses properly. Nerve impulses carry sensation information from nerve endings in the body to the brain, as well as instructions from the brain to the parts of the body.

When you interfere with this transfer by squeezing the nerve pathways, you don't have full feeling in that body part, and your brain has trouble telling the body part what to do.Health Question & Answer
