blackout shield

Because even 10 lux is too much.

Street lights. Passing cars. A neighbor's porch light. Your phone charging across the room. Even low levels of ambient light during sleep — as little as 10 lux — are enough to suppress melatonin by up to 50%.

Blackout Shield installs instantly with suction-cup mounts — no drilling, no damage, no landlord conversations. It creates total darkness in any room in under a minute, and rolls away just as quickly in the morning.

Designed for renters, travelers, and anyone whose bedroom isn't as dark as their biology needs it to be.

The Science

Even light exposure during sleep — not just before it — continues to suppress melatonin and shift circadian phase. A 2019 study found that sleeping in a room with just a bedside lamp on (100 lux) reduced melatonin by 50% and impaired next-day glucose metabolism. Total blackout isn't an aesthetic preference — it's a biological requirement for optimal sleep hormone cycling through every stage of the night.
