Circadian Lighting Design

What is Circadian Lighting Design?

Strategically adjusting home lighting color temperature and intensity throughout the day to match natural light cycles, supporting melatonin production, sleep quality, alertness, and circadian rhythm health.

Is there evidence for it?

How do you do Circadian Lighting Design?

1. 1.Morning (6-9am): use bright, blue-rich light (5000-6500K color temperature) or get 15-30 minutes of direct sunlight exposure to suppress melatonin and anchor your circadian clock
2. 2.Midday (9am-4pm): maintain bright cool-white lighting (4000-5000K) in your workspace; position desk near windows for natural daylight
3. 3.Evening transition (4-7pm): switch to warm-white lighting (3000K); remove overhead fluorescents in favor of side-lighting and lamps
4. 4.Pre-sleep (7pm-bed): use amber or red lighting (2100-2700K); install smart bulbs that auto-dim and shift warm, or use dedicated amber bulbs in bedroom and bathroom; enable night mode on all screens
5. 5.Night: achieve complete darkness for sleep; use blackout curtains and cover all LED indicators; if you need a nightlight, use red/amber only (these wavelengths don't suppress melatonin)

How long does it take?

2-3 hours initial setup; then automatic.

Is it hard to start?

easy.
