Hence, I'm interested in what you say about sleep patterns and health. Any links?

Yep, they sure have. I see reports regularly. Look at this one (I posted a link to it yesterday.

Some people might have no problem, other have chronic insomnia that is being linked to using a computer, watching a TV or reading on a tablet. Reading a conventional book - or on an eReader - does not create the problem. I had several years of difficulty sleeping - diagnosed as Narcolepsy at one stage - all of which disappeared when the sleep clinic I was referred to stopped me using any device that actually emitted light (for at least three hours) before attempting to sleep. The effect was instant, and for me almost magical. Using a computer or watching TV has become such a ubiquitous part of our lives that many never consider it to be a problem.
Insomnia among children has become almost epidemic in some demographics, but not among those who do not have access to devices with screens, or who are not allowed to watch TV until bedtime. As I said, it isn't everyone, but for those who do have difficulty sleeping, avoiding light emitting screens can solve a lot of problems. Ever noticed how many very young children nowadays have bags under their eyes?
