Augment your energy with NightCove. NightCove is designed to render you better-quality sleep and to make you feel more refreshed in the morning. By using LED technology, it emits wavelengths, intensity and variations of light, which affect the brain’s production of melatonin, a hormone that helps regulate sleep-wake cycles. With programmable modes for falling asleep, napping and waking, the NightCove uses colors to mimic dawn and dusk guiding users in and out of wakefulness.
