Adopting a left-side sleep habit is a form of “passive wellness,” where long-term health is optimized through structural alignment rather than active effort. While muscle memory may make the transition difficult for lifelong “right-siders,” tools like body pillows can help train the nervous system to maintain this new orientation.
By acknowledging that internal health is often a matter of geometry, we can turn sleep into a true restorative ritual that reduces friction within our systems. Ultimately, choosing the left side ensures that the third of our lives spent in unconsciousness is utilized for maximum vitality and biological ease.
