Electronics and very bright nighttime lighting are a ton of it. Cutting those out would turn a hell of a lot of “night owls” or people who “can’t sleep” into people who sleep on a normal schedule just fine. It’s obvious when you consider what all that stuff really means. Obviously it’s hard to sleep when you spend your hours after sunset in hundreds-of-candle-power lighting and have hyper-stimulation of a hundred kinds available at the press of a button. Of course there’s also apnea and kids and such, but that’s a large proportion of the problem, overall.
