Start with five changes.
Redesigning a bedroom is a project, and projects are easy to never start. So the Bedroom Design Guide opens with five changes — chosen not for maximum impact, but for the intersection of real impact and genuine achievability. Every one is reversible. The point isn't to fix the room in an evening; it's to make five changes that work, so the rest feels possible.
What this is
The opening of the guide, in full
These five are the first section of the Bedroom Design Guide — 126 pages, 40 interventions, organised around five goals: falling asleep, staying asleep, winding down, waking at a workable time, and feeling safe enough to rest. This page is that opening section, published free and ungated, so you can start tonight whether or not you ever read the rest.
Each change names the mechanism it works through and its real cost and effort — exactly as the guide does. Four of the five are about light and darkness, because that is the cheapest, most universal lever a bedroom gives you; the fifth is about timing.
The five
Where the guide says to start
-
01
Standby-LED elimination — every source counts
After 20 minutes in darkness the eye fully dark-adapts — sources invisible in daylight become visually prominent. A single blue standby LED at 3 m delivers 2–5 lux at the pillow, within the melatonin-suppression threshold. A roll of black electrical tape is most of the fix.
-
02
Blackout window treatment — curtain + recess blind
A true blackout takes two elements working together — a wide-hung curtain to cover the wall edges, and a recess blind to seal the top gap. Either one alone leaves a light path large enough to suppress melatonin. This is the heaviest of the five; it is also the one most people notice first.
-
03
Night-time proprioceptive safety
Sleep inertia — the cognitive and motor impairment that follows waking — reduces balance, proprioceptive processing, and spatial working memory for 5–30 minutes. For DCD and hEDS profiles, where proprioception is already less reliable, night-time navigation is a fall risk, not a preference. A low, motion-triggered light on the path handles it.
-
04
Eye mask — portable, rental-proof blackout
Where window treatment isn't possible — rental restrictions, travel, a shared room — a well-fitted eye mask delivers functional blackout at the point of need rather than at the room level. It is the fallback for move 02 and a complement to it.
-
05
Consistent waking time — the circadian anchor
The internal clock runs at about 24.1 hours and has to be reset daily. Your waking time determines when the resetting light signal arrives — which sets your melatonin timing for the following night.
The only one of the five that asks for daily consistency rather than a one-time change — free to start, but the upkeep is the work.
In the guide, each of these gets a full card — the steps to do it, the target to hit, a test to check it worked, and an adaptation for when the standard version won't fit your room. The full guide also carries paths for seven conditions: DSPD, hEDS, POTS, MCAS/MCS, Visual Stress, ME/CFS & Long COVID, and chronic pain & fibromyalgia.
One boundary, stated plainly. Sensori is environmental intervention, not clinical care — it changes rooms; it doesn't assess, diagnose, or treat. Where a presentation needs a clinician, that's the right next step, not a redesign.
