How does a body part "fall asleep"?
i think this phrase is thrown around, how exactly do u know when a limb has fallen asleep? i do get this weird tingling feeling when i keep my leg or arm in one position for a little while and it feels kinda swollen like the blood just stopped coming or something but i never knew if thats the feeling people talk about when they say somethings fallen asleep, cause i can still move it and stuff so how do u know when somethings fallen asleep???

Blood flow is restricted. Like when you sleep on your arm and wake up and can't sense it, but know it's there. When you move it to a more comfortable position, you still can't feel it in motion even though your brain knows it's moving (the receptors think it should be moving anyway) because the nerves and sensors in your arm are deprived of a fresh supply of blood.
Close your eyes and move your arm- you can feel it (in the arm itself) that it's moving.
Supposedly, it's easier to break a bone when the blood flow to an area is restricted.

Body parts are like some other materials of things too...They require detailed monthly exams and relaxation time...Once they go to sleep...It customarily method to vary the oil or that they need to be repaired or simply rested...It'll work again after a just right r&r session...
when blood flow is restricted to a limb the lack of blood causes a tingling sensation. Its just a phrase like "hold your tongue." It doesn't literally mean to hold your tongue but to just not speak.
That's called parasthesia. It happens when pressure is applied to a nerve, which reduces it's function and causes the pins and needles feeling you get.
It can also be caused by a neurological disorder or certain blood diseases.
I reckon that's what it feels like when you die, except the part after that when you cant feel it and it feels dead, but first starts with tingling.
when you lose all the blood in it.
