Bad research! > Pre-industrial societies such as the Hadza tribe in Tanzania also seem to have a far lower prevalence of sleep problems, like insomnia. “When we asked members of the Hadza whether they thought their sleep was good, they almost universally said ‘yes, it’s totally fine’. That statistically doesn't match up with what we see in the West,” says David Samson, an anthropologist at the University of Toronto in Mississauga, who has studied them. This is what they actually found from that Tribe and a second one. They actually got less sleep then people do living with artificial lights. > The team asked 94 people from these groups to wear Actiwatch-2 devices, which automatically recorded their activity and ambient-light levels. The data revealed that these groups all sleep for nightly blocks of 6.9 and 8.5 hours, and they spend at least 5.7 to 7.1 hours of those soundly asleep. That’s no more than what Westerners who have worn the same watches get; if anything, it’s slightly less. https://www.theatlantic.com/science/archive/2015/10/the-many-myths-of-paleo-sleeping/410707/ https://www.theatlantic.com/science/archive/2015/10/the-many...

This was talking about the idea that we naturally sleep a little and wake for a few hours and then go back to sleep as some normal human sleep pattern. The idea is still the same we sleep about the same in modern times. I have had to read a lot of ancient documents and in those documents they talk a lot about bad sleep medicine. If they sleep so well why do we have so many sleep fixes in those documents. https://link.springer.com/chapter/10.1007%2F978-1-4939-2089-1_4 https://link.springer.com/chapter/10.1007%2F978-1-4939-2089-...
