Streetlights, standby LEDs and a sliver of dawn leaking through the curtains — that glow was quietly wrecking my nights. One small change turned the whole room off, and sleep finally showed up.
12am the bedroom felt busy. The router winked, the alarm clock bled red, and the orange wash from the street turned the wardrobe into a shadow puppet. I wasn’t awake for a reason; I was just… awake. It’s the sort of wakefulness that makes your brain bargain — one podcast, one scroll, one more sip of water — then the birds start and you’ve lost the morning. I realised the room wasn’t dark; it was pretending. I got out of bed, taped the tiny lights, and held the curtain edge to the frame. The room went still, like a cinema hush before the film. I tried it properly the next night with a simple upgrade. The result surprised me. A lot.
The tiny change: I made the room truly dark
I turned my bedroom into a cave. Not moody, not cosy — **true darkness**. Within two nights, my mind stopped doing the 3am parade. The air felt heavier in a good way, as if the mattress had finally found me. Mornings didn’t feel heroic. They felt clean. I got out of bed without a negotiation.
The numbers backed it up. My watch’s sleep score jumped from the low 60s to the mid 80s by night seven. Deep sleep nearly doubled, from about 50 minutes to just over an hour and a half. Nightly wake-ups slid from four to one. Resting heart rate dropped by 4 bpm; HRV nudged up by 20%. It wasn’t a lab. It was a normal week with the same job, same dinners, same stress. The only thing I removed was light.
Light leaks tell your body the wrong story. Your eyes have cells that don’t make pictures; they read brightness and send that signal straight to your clock. Even a tiny LED can act like a false dawn. Blue-white tones are the loudest, but any glow can nudge melatonin off its track and fragment sleep. Darkness isn’t a mood choice. It’s a biological cue your brain expects at night. Remove the light, and your system stops getting mixed messages.
How I blacked out the room in one afternoon
I started by hunting light like a detective. Phone on, camera up, lights off — anything glowing got covered with matte tape or purpose-made light-blocking stickers. I pinned the curtain tops so no halo escaped, then added cheap blackout liners behind them. A strip of self-adhesive Velcro sealed the curtain edges to the wall. The alarm clock turned to face the wall. A warm, low lamp went on a timer for wind-down. The result felt immediate.
Little errors matter. Gaps above the curtain rail leak more than you think, so use a simple pelmet or even cardboard for a test. Reflective blinds bounce streetlight back at you; go for fabric that eats light, not mirrors it. Masks help, but they slip. Keep a mask as backup, not the main event. I also moved my phone to the hallway and taped the doorframe’s keyhole glow. Let’s be honest: nobody actually does that every day. Do it once and forget about it.
We’ve all had that moment when you blame stress for a bad week, then change one detail and the whole puzzle shifts. That was this. A small, stubborn fix that worked faster than any app or supplement.
Darkness is the cheapest sleep upgrade I’ve ever tried. When the light went, my brain finally got the hint.
- Blackout liners + Velcro for curtain edges
 - Matte tape or light-blocking stickers for LEDs
 - Low, warm bedside lamp on a timer
 - Eye mask as a safety net, not a crutch
 - Draft excluder to block hallway glow under the door
 - Optional: a red night light for loo trips
 
Seven nights later
By the end of the week, the change felt bigger than the kit. I woke before my alarm with that crisp, early-walk feeling. Dreams came back in colour. The 4pm slump softened. I was less quick to snap, more quick to laugh. Not perfect — real life still leaks in — yet the baseline shifted. **Sleep quality doubled** isn’t a slogan; it was a quiet, stubborn pattern. The room learned to be night again. Your bedroom might be two pieces of tape and a strip of Velcro away from the same relief.

FAQ :
- Does making the room darker really help?For many people, yes. Even tiny amounts of light can fragment sleep. Cut the glow and your body gets a strong “night” signal.
 - Do I need expensive blackout curtains?No. Blackout liners, Velcro on the edges, and a pinned top can outperform pricey drapes. Bin bags and painter’s tape work for a weekend test.
 - Is a sleep mask enough?Often helpful, but masks slip and leak. Treat it as backup. Darken the room first, then add the mask if you like that cocooned feel.
 - What about mornings — won’t I oversleep?Step into daylight soon after waking. Morning light anchors your clock so nights feel darker and days feel brighter. It’s a simple loop.
 - Is it safe to cover device lights?Cover the LEDs, not the vents. Use low-heat tape or stickers and keep electronics ventilated. If in doubt, switch devices off at the plug.
