Humans, all animals really, run on an internal clock known as a circadian rhythm. Well, maybe I should say that humans SHOULD run on a circadian rhythm. A proper schedule becomes harder and harder to maintain as we work more, sleep less or just sleep at the wrong times. Since our circadian rhythm is governed mostly by the Sun, the Circadian Sleep System clock uses an array of white and blue lights to help adjust our schedule.
The lights of the clock glow at varying intensities to promote a perfect circadian schedule, and in theory, provides you with deeper rest and more energy when you wake up. At almost $250 this is not your average alarm clock investment, but if you’re desperate to maintain a normal schedule, it might be worth a try.
