Sleep alert! Blue light has a dark side – Harvard Health Publications

I woke up an hour early today because I felt well rested. This never happens. I usually need about 10.5 hours a night (a sleep study I did showed I woke up 14 times an hour, which is probably why). I take supplements and Silenor (doxepin) to get that sleep. I also have trouble getting to bed before midnight, because I have elevated night time cortisol. What was different about last night?
I turned off the TV at 9. After reading about the harmful effects of screen time on your sleep, I thought I would give it a try. I also downloaded a blue light filter on my phone and tablet to avoid exposure.
Give it a try!
