A Digital Sunset: The Hour That Repairs Your Sleep

Most sleep advice starts at bedtime. Better sleep actually starts an hour earlier — with letting your screens set before you do.

Bright, fast-moving feeds keep your mind in daytime mode. Melatonin — the hormone that makes you feel sleepy — rises most easily in dim light and low stimulation. Give it an hour of dusk, and it does the work for you.

• Choose a sunset time — if you sleep at 11, let devices "set" at 10. Charging the phone outside the bedroom makes the decision once.
• Replace, don't just remove — fill the hour with something dim and slow: a paper book, gentle stretching, caffeine-free tea.
• Let your mind land — if worries surface, write them on paper. The page can hold them overnight so you don't have to.

Some nights you will scroll — a digital sunset is a direction, not a rule you can fail. The next evening is always another dusk.

The hour before bed is not really about blue light; it is about arousal. A screen is a door to other people's urgency, and urgency is what keeps the body upright. Dim the room, yes — but the bigger lever is refusing to open one more thing that will need a response.

Give the hour something to be, not just something to avoid: a book, a shower, tidying one surface, a tone playing low. An empty rule breaks by Wednesday; a filled one survives. Breath & Sleep (呼吸與睡眠) is essentially an hour with a shape, which is why people can keep it.

Sleep begins before bed. One dim, screen-free hour tells your body the day is truly over.
