Sleep Position Training

Training supine sleep to prevent facial asymmetry

Deliberately training to sleep exclusively on your back with the head in neutral alignment, based on the theory that years of side or stomach sleeping creates cumulative compressive forces on the face that cause asymmetry, skin creasing, and midface flattening. Methods include cervical pillows, rolled towels along the sides, and positional alarms. CONTROVERSY: While sleep position does demonstrably cause skin sleep lines (supporting silk pillowcase use), the claim that it causes significant skeletal facial asymmetry in adults is not established by evidence. Some sleep-position training may actually worsen snoring or sleep apnea in certain individuals. Consult a sleep specialist if you have breathing issues before changing your sleep position.
