Night Light

In 2012, after reviewing the evidence, the American Medical Association released a major statement, night light can disrupt your sleep cycle. However, for whatever reason, not many people have been since informed about it. So here is the basics of what you need to know. When you're exposed to a significant amount of light, specifically of the blue wavelengths, your body suppresses melatonin production to make you feel more awake. Normally this evolutionary design works pretty well. With the coming of night and day, our melatonin levels waxes and wanes giving us a circadian rhythm. However since the invention of artificial lights, we're being exposed to more and more light at night time and these effects can be pretty big. Here's what happens when you place participants in a room with similar brightness to your average household. This is where their melatonin levels would normally be if they were sleeping in a dark room, and here is their malotonin levels in that lit room. You can see the huge suppression of melatonin and it doesn't take too much to see these effects either.
