Good article but you missed two things that are important and people need to know.
First, it is unnatural for humans to sleep eight hours straight. We sleep bi-modal — at least pre industrial revolution. Carnegie Mellon historians proved it. An hour or two awake in the middle of the night is ok. Work with it. Don’t fight it.
Second, a good indica edible is the best sleep aid on the planet. Zero side effects other than a little groggy if you ate ( or vaped) too much. Thousands of people are ditching Pharma for cannabis for sleep everyday. It’s adding up to millions of people and only getting bigger.
Look into it. Write about it. Your audience will be exponentially bigger because they know it, unlike the relatively small audience who own expensive and fancy high sleep tracking devices.
