So light and dark, really important light throws off their circadian rhythm, throws off that internal clock. It delays melatonin, which is a hormone that starts the sleep process. So lightness and darkness. So incandescent light, blue light. I'm sure you've all heard about blue light. Incandescent light, worst form of light at night for signaling daytime. So your circadian rhythm says, oh, blue light. It's light out. It's daytime. This screws you up. Says your melatonin should not start. Keep us awake, don't start. Melatonin sources are electronic devices, TVs, computers, smartphones. It's all over the place. Fluorescent lights, LED lighting, protection from blue light. There's blue light blocking glasses. At night, you can use these glasses. Screen filters, blocking plugins, comfort view settings. So it throws off the circadian rhythm, doesn't let the melatonin be released. Good thing to do, by the way, is to let sunlight wake you. Bend your alarm clock, Let darkness put you to sleep. When it's starting to get dark, start turning the lights down.
