NASA has planned an experiment to attempt to help astronauts get sleep on the international space station. According to research, blue light helps wake people up while red light helps people fall asleep. This apparently means that staring at my computer screen before going to bed apparently doesn't help me fall asleep. But it does mean that my alarm clock should be heavy on the blue light to wake me up in the morning, and it could also have RGB LED's that go heavy on the red light as I'm getting ready for bed. That could help mimic the sunrise and sunset and give me a sleep pattern that is either more stable (because it's easier for me to fall asleep and wake up) or that is more easily tuned because I can give my body the necessary light cues to tell it to fall asleep when my work lets me. Either way, I'll need to experiment. And for that, I need the clock.
