illumy aims to help you get the sleep you need using the power of natural light. By programming it on a companion app or by pressing the button on the mask, illumy provides a gradual dimming sunset to nudge you into sleep. In the morning, the same functionality of programming your app or by pressing the button — illumy wakes you with a blue sky before your set alarm time. This scientifically-proven regimen is used on the international space station to help astronauts’ body clocks stay in sync.
