When your leg goes to sleep, a condition called paresthesia, it's because the blood circulation has been interrupted to your leg. What I usually do is reposition my body so that circulation is restored to my leg, then try not to move the leg as circulation is restored. Movement will cause pain and tingling during recovery from paresthesia, and it is not necessary to restore circulation (beyond moving to restore circulation).
You can cut off the circulation in your leg if you sit for too long causing your leg to tingle or feel numb. Shaking your leg might be a way to stimulate circulation again.
This could be a medical emergency. Leg could have circulation problems. If leg has no pulse, you could lose the leg. Go to the emergency room.
Smoking restricts circulation, and restricted circulation slows down healing.
Because you are not getting enough or any circulation.

Leg exercises improve circulation and prevent blood clots
You may have a circulation problem.
I have had this and it is usually bad circulation; i.e. when my leg "goes to sleep". Try shifting positions frequently when sitting to allow your blood to flow evenly through your legs, and take note of what position you are in when it happens.
Stasis dermatitis, a consequence of poor circulation, occurs when leg veins can no longer return blood to the heart as efficiently as they once did. When that happens, fluid collects in the lower legs and causes them to swell
you get one wet leg
