Why does my hand always fall asleep ?

After a couple minutes of writing longhand, my hand gets all tingly and feels like it's falling asleep. Sometimes I wake up in the middle of the night with the same feeling in my hand. What can I do to prevent this?

Answer:
this can be due to lack of circulation
having pressure on certain parts of the body can also cause this
rub your veins from the inner part of your arms up and down
and around the wrist this might settle it down.
also seek medical advise from a physician there are treatments

Answer:
Tell your hand to take some sleeping tablets. When it wakes up it will be fine.

Maybe its lazy and doesn't want to work for a living !!!

I advocate slicing it off… (not literally you dill .. i mean discommunication and boycotting it)
