Sleep
The highest-leverage, least-monetisable health habit there is.
Sleep is the one health input with an enormous effect size, no subscription and nothing to buy. Which is exactly why the internet has spent the last few years inventing things to sell you for it.
These guides separate the parts with trial and cohort evidence behind them from the parts that are a nice ritual, and from the small number of viral habits that are genuinely risky. Every claim is graded and cited.
