Why Do Feet Fall Asleep?
Occasionally, if you sit on one of your legs for a long while, the circulation of blood to your foot slows down. When this happens, your blood can’t carry the poisonous wastes out of your cells.
These, wastes accumulate and block the nerve cells from sending messages to your brain. Your foot feels numb, and we say it has “gone to sleep.” When you stand up and stretch your foot out, blood suddenly starts flowing again. Now the nerves in your foot “wake up.”
The nerve messages they send make your foot feel tingly as circulation returns to normal. The pins and needles sensation is annoying for a few minutes, but it’s a nice little prompt for us to relieve the pressure on one of the legs before serious nerve damage occurs.
Everyone experiences these feelings from time to time, and they’re completely normal. They don’t hurt your body, but they sure can feel really strange for a short time until your brain and your body starts communicating again!
