>There have been many links between increased blue light and reduced REM/restful sleep The only decent study I know of about blue light and sleep, was done before the LEDs in phones/tablets/kindles even existed. Which means they were using more traditional light sources that were likely putting out an order of magnitude more luminosity. Everything that suggests tablets/phones/kindles interferes with sleep are woo-woo blogs trying to affiliate link sell you orange safety glasses and similar nonsense. If these devices ARE affecting sleep, it's likely the level of mental stimulation they are providing and the fact that when most people get into bed, they don't shut their mind off and instead start thinking about how Sally post pictures of her 13th fancy meal in her 13th country this month and how John's abs pop way more than theirs and it's just not fair because they count their macros and train and train and just can't get abs like that or they're mad that SniperLulz127 fragged them 4 times this evening in Overwatch Fortress 7 Call of Defeated Zombies.
