Okay, but none of that is relevant to the article. This article is about a genetic condition called FNSS which results in you getting a full night's sleep in less time. It specifically addresses the concern that there might be unobserved negative effects and that so far, we haven't found any. If you have FNSS there is no reason to try and force yourself to sleep for 8 hours a night and it is not something being sold on YouTube.

You’re missing the point being made in this thread, which is that there might be subtle long-term impairments to the genetic condition described in the OP.

Indeed the article discusses this thoroughly, noting that since it’s a very small sample you can’t rule out anything but very strongly negative fitness impact.

There’s simply not enough data to rule out the hypothesis that folks with this condition are slightly sleep-deprived vs their theoretical without-mutation genotype baseline.
