Why do my legs fall asleep sometimes? What makes this happen?

Answer 1

If your legs sit still for a amount of time the blood flow starts to slow done and the nerves relaxes a little .

Answer 2

Sometimes when you sit with your legs crossed or sit with the back of your legs up against something like a hard chair you are slowing down the circulation to your legs.
Your nerves quit receiving their needed blood supply and they tend to quit functioning properly. . . over a lengthy period of time it could cause damage to the nerves.
Once we start feeling the "falling asleep" sensation we usually start moving so there is actually little chance of the above mentioned nerve damage.
Once we start to move or we get up from the position we are in that is causing the feeling of our legs "falling asleep",we feel the nerves getting their blood supply back and "waking up" sensation that is comparable to prickly feeling or short "electrical" impulses.

Answer 3

Well If you leave your legs crossed for a while, blood stops running and your leg will fall asleep, and when u take your leg off blood rushes through your leg resulting in pins and needles and sometimes your leg feels like it has sand in it

Answer 4

Legs "fall asleep" because the blood flow to the region is cut off. It usually occurs when your body is kind of twisted or your legs are crossed.

The scientific reason your legs feel "tingly" is because of a lack of blood. Since inadequate blood is flowing to your legs, they won't receive enough oxygen. Oxygen is important in that it fuels cellular respiration, which basically means your legs are getting energy. Since your legs don't have oxygen, they are forced to undergo fermentation. Fermentation allows your legs to produce energy without oxygen, but also creates lactic acid in the process. The lactic acid builds up around your bones, which produces the tingly feeling you have.

Answer 5

Restless Leg Syndrome??

Answer 6

Lack of blood flow.
When blood flow is partially blocked for a period of time and then suddenly unblocked the blood rushes in really fast and all the nerve endings come to life again. The pin-pricks you feel is the sudden overstimulation of nerves.

Answer 7

When you sit on your leg or put your leg on the other. The blood stops, and then when you get up and starts moving and it tingles.(its a weird feeling) It always happens to me because i sit on my leg too much. Don't get scared its no disease.

Answer 8

If you can't move your leg, you pinched a nerve. That's why it feels like pins and needles when you try to move it. All the nerves are "waking up". It's normal, don't worry about it!

Answer 9

Legular Narcolepsy?

Answer 10

I have this happen occasionally, it's annoying. My doctor said it's because I have a pinched nerve in my back. I sometimes go to a chiropractor and that will relieve it for a while.
