This article isn't exactly a presentation of research. Several of those answerable questions will probably be worth Nobel Prizes for the people who can answer them. This is fundamentally a puff piece with a sleep expert promoting his new general audience book on sleep health (Not discounting the tips, or his expertise, but this is obviously not a research paper). Several of the sleep hygiene tips he gives are things that aren't really settled AFAIK in the field, possibly why he even specifically mentions "practicing what he preaches" in that last question. He's preaching at least as much as talking about settled science.
