The article, for all of its other faults, also manages to breeze over another crucial point:

“Research shows that blue light suppresses the body’s production of melatonin, the sleep hormone. This can be helpful in the morning, when you want to wake up…”

I find this to be a much easier habit to maintain, at least during summer: as close as possible after waking up, get as much light as you can, and at a regular time if possible. Sun lamps are an expensive but effective option during darker months, but they generally aren’t covered by insurance.

The first I heard of this was when I spoke to a sleep doctor, and it has worked much better for me than melatonin ever did.

Blue light effects on sleep have been utterly debunked as far as I know. If you google for blue light myth you'll find very convincing arguments that it was all bullshit.
