> The article doesn't really claim that this kind of sleep is better or more natural, just that it was incredibly common. (Emphasis mine.)
For a start, the article suggests that it wasn't just common but actually the dominant pattern of sleep, but the evidence seems a bit thin on that. Moreover, it says that "Ekirch began to suspect that the method had been ... an ancient default that we inherited from our prehistoric ancestors". But I seem to remember an anthropologist on a TV programme (many years ago so I forget which one sadly) saying this isn't obvserved in isolated tribal cultures today, so we can reasonable expect that our pre-agriculture anscestors wouldn't have slept this way.
Edit: A reply to a sibling comment found a good citation: https://www.theatlantic.com/science/archive/2015/10/the-many... Interestingly, like the BBC article it mentions Ekirch as the proponent of the two sleeps theory. So I wonder if the whole idea is the pet theory of this one person.
