Three levers, one architecture: evening light, cool air, steady noise.

Summary

• Light: go warm/dim 60-90 min before bed; morning light anchors the clock.
• Temp: aim a cool room with light bedding; support airflow and CO₂ refresh.
• Noise: mask spikes with steady fan/air purifier or pink/brown noise.

Sleep Window Planner

Pick a wake time you can keep most days (5-6 nights/week). Bedtime follows.

Target wake time Sleep duration (hours)

Your window

-

Tip: keep a +/-30 min band around wake time; shift slowly (<=30 min) when needed.

Cycle guide

-

~90-minute cycles (rough guide) help time wind-down; personalize to how you feel.

Evening Light & Screen Plan

Planned bedtime

Use warm/dim lights; enable Night Shift/Blue-light filters; place lamps eye-level or lower.

Wind-down Script Builder

Pick 3-4 steps for a 20-minute routine.

Warm shower (5 min) Stretch/relax (5 min) Pen-and-paper brain dump (3 min) Dim lights + lamp only No-scroll reading (paper/Kindle)

Nap Guard keeps night sleep intact

Short naps can help, but late/long naps can delay sleep. Use your bedtime to set a safe window.

Planned bedtime

-

General tips: keep naps 10-25 min, and avoid within ~8 hours of bedtime. If insomnia is active, trial a no-nap week.

Keep devices below conversation level; aim for steady, non-rhythmic sound.

30-Minute Setup (start tonight)

Set wake time (+/-30 min) and calculate bedtime. Build your **evening light plan**; place lamps and dimmers. Set **room temp/airflow** and adjust bedding layers. Create **noise mask plan**; test fan/air purifier volume. Sunday 15-min review: adjust one lever only (light, temp, or noise).

FAQ

What's the best bedroom temperature?

Comfort varies; many do well near 17-19 °C with breathable bedding. Personalize to your climate and pajamas.

Do I need blackout curtains?

They help if street/early light wakes you. Eye masks are a lower-cost alternative.

Which noise is best - white, pink, or brown?

Try pink/brown for softer masking; a fan/air purifier works for many. Keep volume below conversation level.

How strict should my wake time be?

Keep within +/-30 min on most days. If you have to shift, do it gradually (<=30 min steps).

Will this solve my sleep entirely?

No single lever fixes everything. These three make nights more repeatable; pair with your broader plan and clinical guidance.
