Biggest improvement to sleep quality I had was giving up caffeine, which isn't mentioned in this article.
I'm inclined to bet, most people in the west who self report suffering form poor sleep, can narrow it down to caffeine over-consumption, since it leads you slowly to this march of death burning the candle at both ends where you drink coffee to compensate for poor sleep and you sleep poorly because of too much caffeine.
