Beyond just brushing your teeth: craft a wind-down routine that signals safety to your nervous system.
Sleep is not something you do. It's something your body allows — and only when it feels safe. Most modern evening routines fail to send that signal.
The Three Signals of Safety
Temperature: a warm shower followed by a cool room tells your body that daytime is ending.
Light: dimming lights 90 minutes before sleep mimics the natural dusk your ancestors experienced.
Routine: doing the same sequence of actions trains your nervous system to anticipate rest.
