Since learning about LCHF and the misinformation related to CICO, good carbs, sugar etc. I am seeing similar issues with concerns over blue light at night.
There seems to be hundreds of sleep specialists who blame blue light, late at night causing people to not get enough sleep and this is even being linked to obesity.
As a kid I knew many children who had to have a landing light on when going to bed. And that is from the 1970s when we weren’t obese.
So is this blue light a real issue or is it because we are obese and ill from bad food?
Like with nutrition I’m looking for solid scientific studies about this blue light issue. Not sleep experts making tenuous links with circadian rhythms. Ideally studies that isolate blue light as the cause of sleep and memory issues.
Thanks to all
