CircadiaOS: Tune your bedroom for sleep

Temperature is the single most controllable input to sleep quality. Sleep is the single most controllable input to human health. Health is the foundation of every other thing you do with your life. CircadiaOS is built on that chain.

Most people sleep in a room set to one static temperature all night. Your body doesn’t work that way. Core body temperature drops into deep sleep, rises through REM, and cycles every ninety minutes. A static thermostat fights your physiology for eight hours a night, every night, for decades. CircadiaOS fixes it.

Software-only. No mattress pod, no proprietary sensor, no new hardware to buy. It bridges two massive, fast-growing markets people are already in: wearables (Apple Watch, Ōura, Whoop, Garmin) and smart thermostats (Nest, Ecobee, Honeywell).

By connecting devices millions already own, they deliver personalized sleep science without the hardware markup.
