Why the Side-Sleeping Position Is the Most Exposed

Sleeping on your side concentrates the full weight of your head on a single area of the face for hours, unlike back-sleeping, which distributes pressure without direct contact between the face and the pillow.

Changing Position Isn't Always Realistic

Sleep position is largely unconscious and hard to change durably; reducing the friction of the fabric the face stays pressed against is a simpler adjustment to maintain over time.

"Switching to back-sleeping eliminates direct contact, but for those who have always naturally slept on their side, pillowcase texture remains the most realistic lever to pull. "

A Realistic Adjustment Rather Than a Radical Change

Rather than forcing a change in sleep position, reducing the friction of the fabric that stays in direct contact with the face is the simplest adjustment to maintain every night.
