Is sleeping with pillow better for your body?

Camille T.
Sometimes. If i feel my back hurt, i'll sleep without pillow. But if i feel just fine with my back, then i'll use my pillow.

I'm not entirely sure I tried sleeping with one pillow, I've tried sleeping with two pillows, I did read however, it is better to sleep with a pillow where just your head is lifted to a line with your spine.
