Or perhaps, it is simply that healthier people have more efficient body systems and better immune systems and therefore need more sleep, which naturally causes them to sleep less by default.
This is the problem with correlative studies.
This study does not in any way suggest that sleeping less will lengthen your lifespan. At best, it only says that the amount of time you sleep is correlated to the length of your lifespan. No causal relationship can be assumed.
In it’s credit, the article does admit that more study is needed.
Indeed, for instance people with sleep apnea spend much time “sleeping” but get very little actual sleep, and have quite poor health as a result. But it’s no the oversleeping that’s a problem, it’s the inefficnecy of the sleep.
Yes, I do. :-p
