Answer: Sleeping on your left side

Clues: “Position” and “West” (as in on West side when facing North)

The Hull Daily Mail says sleeping on your left side can improve your health and reduce snoring. Doctors also recommend left side sleeping for those with heartburn or gastric problems. They caution against sleeping on your stomach because it can cause spinal, joint and nerve problems in addition to chronic neck and back pain.
