Why do people use pillows when they are sleeping in their bed?
Cuz rocks r 2 hard... Did u really just ask that??
Because it's comfortable?
It's comfy! Have you ever tried sleeping without a pillow? It's miserable! aaannnd people don't only use a pillow in their beds...you can use them in the car, on the floor, or anywhere else, really.well maybe not underwater.
Its comfortable because your spine is shaped with a curve in your neck. The pillow lets your neck relax.
Hmmm, good question but I've heard that it has something to do with there neck or brain. Not sure. (thinking face)
So my knees dont touch
What kinda of question is that?!
If you don't use a pillow, you may put unnecessary strain on your neck, and may cause a very sore neck.
