This is the night mask that employs light technology developed by NASA to help astronauts regulate their sleep. Astronauts aboard the International Space Station who are exposed to red sunset-colored lights at night and bright blue light during the day helps to combat the insomnia and other sleep disorders they experience when their circadian rhythms are disrupted. This comfortable mask blocks all ambient light to gradually lull one to sleep by shining the dimming warm tones of a setting sun, and in the morning helps one to gently wake up by shining brightening blue lights like a dawn sky. For enhancing sleep, the mask’s sunset can pulsate in a rhythm similar to the Delta waves the brain produces during deep sleep and accelerates in the morning to help rouse one without grogginess. All settings, including the length of the sunrise and sunset, are controlled via a free smartphone app. Powered by rechargeable battery.
