Holi's SleepCompanion has combined the principles behind a sunrise alarm clock with the skills a sleep tracker in hopes of producing a Super Servant of the Snooze whose whole is wholly greater than the sum of its parts.
In appearance, the SleepCompanion is a light bulb. It replaces any existing bulb in your bedroom, and then connects to any iOS 8+ or Android 4.3 phone/tablet via Bluetooth Smart. Embedded sensors in the bulb enable it to adjust its lighting levels based on the time of day, combining different types of LEDs to influence your body's melatonin (sleep hormone) levels. According to Holi, there is a scientifically proven correlation between lighting wavelengths and the body's secretion of melatonin. So when it's time to sleep, the SleepCompanion emits a reddish light, a color free of melatonin-inhibiting wavelengths. At wake-up time, precisely-defined blue wavelengths of light act to decrease the level of melatonin, and pull you back to reality smoothly. For those who have trouble falling asleep, the bulb and its accompanying app can also play a light-guided relaxation program.
SleepCompanion sensors also take environmental readings throughout the day. They track bedroom temperature, noise, and brightness levels, and can pair if desired with several other environmental sensors and wearable tech devices to help you further understand your sleep patterns and what might be affecting them. Compatibility ranges from the Netatmo weather station and Nest thermostat to Withings and Jawbone activity trackers. Throughout use the SleepCompanion app provides feedback about your sleep, showing the results of its sensor readings, analyzing your sleep patterns, and pointing out when your night didn't seem to be restorative enough. In addition to stating the metrics, the app also offers personal and actionable advice for improvement and how to get the most out of the hours you're in bed.
