Answers:
the lack of blood thing is a myth, it has nothing to do with blood!. the reason why your limbs fall asleep is because putting them in a certain position or putting something on them can pinch a nerve, which cuts off the feeling to your leg!. cutting off the blood circulation just makes your limb turn blue, and can damage it if left that way for too long!.Www@Answer-Health@Com
When you apply 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!.
This pressure can also squeeze arteries, stopping them from carrying nutrients to body cells!. Without these nutrients, the nerve cells may behave abnormally, which can further interfere with communicating bodily sensations!.
Due to both these factors, the information transmitted from the body part becomes somewhat jumbled, and the brain receives strange messages!. Some nerve cells don't transmit any information and others start sending impulses erratically!. This causes you to feel a strange tingling sensation, which actually serves an important function!. Your foot falling asleep for 10 minutes doesn't pose any health threat, but if you were to cut off circulation for an extended period of time -- several hours -- you could suffer serious nerve damage!. The initial tingling sensation tells you that you might want to readjust your position!.
Once you do move your foot, stretch your legs, or roll over off your arm, the nerve impulses begin to flow properly again!. You don't regain feeling right away, however!. There is a certain amount of re-adjustment time before the nerves transmit impulses correctly again!. This increases the intensity of the tingling, causing the familiar "pins and needles" sensationWww@Answer-Health@Com

This happens if a nerve supplying the limb becomes trapped for a while!. The nerve signals are blocked so you lose sensation in the area that the nerve supplies!. Since you normally release the nerve after a while, it regains function as it becomes 'untrapped'!. This take a few minutes so whilst this is happening you are getting sporadic and confused signals from the nerve which is felt by us as pins and needles/tingling!.
It's harmless and perhaps amusing to see which nerves supply which area!. I!.e leaning on your elbow for a long while will block the ulnar nerve supplying the little finger side of your hand! Heh well amusing to some maybe!.
If you stay on the nerve for a lung time- such as passed out unconscious, you can damage the nerve permanently and lose function in the limb!. This often will happen to drunks who can pass out in very awkward positions and dont wake up and release the nerve in time!. It takes hours and hours though so mostly it's fine!.

the blood circulation is cut off!. it hurts the limb because it needs blow flow to have to take to the brain tell tell it "every thing is working" and when it happens to be cut off, it goes crazy!.!. Www@Answer-Health@Com
They "fall asleep" because of inadequate blood flow!. They tingle when blood is reintroduced to the area!.Www@Answer-Health@Com
