Protecting your sleep doesn't require strict discipline, just one clear boundary. "Lights-Down" rule means choosing a fixed time each night to switch to warm lighting and move your phone out of the bedroom, giving your body a clear, low-effort signal that the day is ending.

Wisdom to Carry
夜更かしは百害あって一利なし
What it means in modern life: Late nights often feel like "me time," but they quietly tax tomorrow. Protecting sleep is a form of self-respect.
Begin Here
Protecting your sleep isn't about restriction, it's about giving your evening a clear edge, so your body knows where the day ends and rest begins.
The Ritual: Set Your Lights-Down Time
One step, every evening:
Choose a "lights-down" time, even just 15 minutes earlier than your usual bedtime. When it hits, switch to warm lighting and put your phone to charge outside the bedroom.
This single boundary removes the need for willpower later in the night. The decision is already made.
Food for Thought
What am I trying to get from late nights and how else could I receive it?
One small decision, made a little earlier, is enough to protect a whole night's rest.
