Why does your foot fall asleep?

Question

It's so annoying.

You sit on it for a few minutes and you're punished with a 10 minute long agony of the feeling of getting needles stabbed into your foot.

Why does it do that?

Answer 1

your foot does that because the way you sitting on your foot. you were cutting off the blood flow so the foot becomes deprived of the oxygen.  You get those little needles when the blood rushes back in after circulation is restored.

Answer 2

when you sit in one position for a long time the blood flows to your feet and legs and kind of settles there so when you stand up the blood can finally circulate quickly and that causes the "pain" or so i've heard
