Is it harmful if your arms fall asleep constantly when you sleep?

Answer 1

Oh dear, its not harmful at all. Its actually normal, every once in a while the position you sleep more will numb the part of your body; such as arms are very common, but legs are too. If you don't want to have that happen, you could try sleep with your back on the bottom. Side sleeping can stop the blood running throughout the part you are flattening.
