Why Are Sleep Positions So Important?

The Overall Best: On your back. Sleeping on your back evenly distributes weight throughout your body and avoids unnatural or unnecessary curves in the spine. Use a small pillow underneath the head and neck (not shoulders) to keep everything in alignment. Even better, a small cylindrical pillow in the crook of your neck supports your neck and keeps your head neutral on the mattress. Do note, though, that this sleeping position can cause some people to snore.
