The real reason Americans can't sleep

Countries all across Europe, from Denmark to Sweden, are ripping out their streetlights and replacing them with red ones. The reason behind it should change the way you look at light forever. For all of human history, light after dark was warm. Fires, candles, oil lamps. There was no blue light at night, not once, for 300,000 years. Then around 2010, cities switched to cheap white LEDs to save money, and our phones and TVs got brighter and bluer at the same time. The problem is what blue light does to your brain. It tells your brain it's daytime, so your melatonin, the hormone that makes you sleepy, shuts right off and your sleep falls apart. The American Medical Association actually put out a warning about this. They said blue-rich white streetlights are 5 times more disruptive to your sleep than the old orange lamps, and they link that kind of light to higher rates of diabetes, heart disease, and obesity. That's why countries all over Europe are starting to implement red light streetlamps, and you should do it at home too. Make sure to follow because I share stuff like this every single day.
