Yup, been on the light-water-magnetism road for a while now thanks to Jack Kruse. Blue light, or more generally, non-native EMFs messing with your sleep is even the least worrisome of all the harm it does. Glad more people are seeing "the light" on this. Because all my screens are persistently filtered and my kid is used to this, she can't even look at default setting screens when she's somewhere else because she immediately notices the insane burn.
