What causes limbs to fall asleep?

Question

Hand feet etc...

Answer 1

Lack of blood supply.

Answer 2

Having them in a position that cuts the blood supply will cause them to fall asleep. However, if the limbs fall asleep for no known reason, it's wise to get it checked out. I have multiple sclerosis and it began with my right leg falling asleep.

Answer 3

When you sit on your leg or lay on your arm, for instance, you kind of cut off the blood circulation to that area. Hence, your limb gets all tingly and "asleep".

If your limbs are falling asleep on their own, you might have a pinched nerve and you'll want to see a doctor about it. Otherwise, stop sitting on yourself! lol

Answer 4

Lack of circulation. When the arm or leg is put in a position where the blood veins and arteries are pinched the blood will not flow properly. There are medical reasons for this as well so if you have this problem often then go see a doctor.

Answer 5

if you keep the boby limb in one postion for awhile the blood will stop moving to that limb and when you move it the blood rushes to that spot and has the affect of the limb falling asleep and then waking up

Answer 6

Lack of blood circulation in those particular parts of your body. Notice when you're sitting with your ankle tucked under your leg, your foot has a tendency to "fall asleep" ... it's because the weight of your leg and perhaps the rest of your body was pressing down on your ankle and cutting off the circulation of blood to your foot.

Answer 7

Lack of blood flow

Answer 8

Lack of appropriate oxygen carried by the blood. Oxygen has to reach all the tissues of the body or there is a reaction which causes a mild neuralgia.

Answer 9

Most likely what i know of could be poor circulation.. but to make sure I'd go to the doctor and find out whats going on.

Answer 10

from what I understand, it's due to a lack of blood supply. There's not enough blood flowing to the area so it starts to get numb. (pins & needles)
