The Nightly Cutoff That Rewires Your Sleep Rhythm
In this short monologue, TJ Walker explains that a nightly screen cutoff should be an absolute stop—no muted, dimmed, or partially used devices—at a consistent time each evening. He argues that this works not because of dramatic physiological changes but because it provides clear behavioral signaling to the brain that the day is ending. When the brain receives a clean, repeatable cue, it can more easily establish a regular sleep rhythm, improving overall sleep quality.
