Absolute darkness is essential to deep sleep, whether it’s daytime or nighttime. Your brain can detect even tiny amounts of light through closed eyelids, which can disturb your sleep cycles. The goal is to make your sleep room pitch-dark.
If you share your bedroom with a nighttime sleeper, they too will appreciate your efforts to make your bedroom completely dark. Some street lamps now use energy-efficient LEDs, which emit light in the blue part of the spectrum, which is considered the most sleep-sabotaging kind of all. So blocking out all outside light – during both the day and night – can result in better sleep for everyone.
Use blackout blinds and curtains
Use a combination of blackout shades and opaque curtains to block all light from outside. The best way to make the room absolutely dark is by installing an inside-mounted blackout blind/shade inside the window frame. Then hang outside-mounted blackout curtains on a curtain rod that extends several inches outside the window frame on both sides. The point of doubling up is to ensure total darkness. Even high-end blackout products may allow a tiny bit of light to creep in the sides. A combination of a shade and curtains provides the maximum effect.
How to choose a blind
Cellular shades are the best for blocking out the light. Blinds allow can allow a small amount of light to seep in between the horizontal slats. Roller blinds often eventually curl up and become less effective. Choose the cordless cellular shades, as there’s no chance then of the cord malfunctioning.
Start by measuring the inside dimensions of your window frame. The width of the shade should be slightly narrower than the widow of your window frame- about ¼ to ½ inch. The length of the shade should be long enough to reach the very bottom of your window. If it’s a bit longer, no worries.
How to choose curtains
You definitely want to choose the ones specifically marked as “blackout” and not just “light filtering” or “room darkening.” We’re going for NASA level technology here. The curtains should be long but shouldn’t pool on the floor– you can hem them with hemming tape or bring them to a tailor. Use enough curtain panels… if you think you need one on each side, consider doubling that so you get good thickness and they fully cover every possible inch.
How to choose a curtain rod
You don’t want any light seeping out on either side of the window. There are two options:
- Buy a wraparound rod that curves at the ends so that the curtains can be drawn all the way back to the wall.
- Buy a curtain rod that is at least a foot wider than your window frame. Then draw curtains fully across the windows all the way to the edge of the curtain rod for full coverage.
Swap your digital alarm clock for an analogue one. (Stuck on having a digital clock? Switch to red. Digital clocks with red numbers are considered less disruptive than ones with white or blue digits. Just turn it so it is facing away from you.)
Unplug/cover up electronics
Unplug whatever you can. Use small dots of black electrical tape to cover up any lights on electronics.
Use a “snake” at the door
Block out any light spilling in underneath door frames by placing a snake across the bottom of your doorframe. They are like long, skinny bean bags filled with rice and were often used in old homes to block out drafts. A snake will block out light and muffle outside noises that might sneak in.
