Oversleep can also be bad along some dimensions:

> For cognition only, associations shift to a negative association of sleep duration and cognition for participants sleeping more than 8 hr a day.

Though looking at the charts from the study I can say that Nassim Taleb would not be pleased with how weak the correlations seem to be:

From table 1, the largest significant correlation coefficient is 0.135. This study can be safely ignored.

agreed. this seems far too low and smells more of p-hacking.

Given that one of (emphasis one of) the reasons for long sleep duration is having poor quality of sleep, that doesn't surprise me. And if that is the only cause of negative correlation while other causes are harmless, that could also explain why this correlation is weak, no?

I get extreme headaches if I sleep > 9.5 hours. They're brutally bad. Sweet spot for me is > 6 but < 8.5 hours per night w/ earplugs and a sleep mask on. Quality > Quantity, at least for me.

I average 7 hours of sleep per night and do quite well on it. Used to do 5-6 hours/night and it eventually caught up to me in my 30s, but improving quality via ear plugs + mask + mattress went a lot further than an extra hour of sleep.

Any recommendations on which ear plugs and sleep mask to get? I've moved to an incredibly noisy area and I'm finding my ability to phase this out isn't as good as it used to be.
