Sleep is like drinking water. No one says, "I'm gonna get dehydrated right now and then drink a lot more water later so it's OK." But people do this for sleep. You need to sleep right when you're tired, because being tired is a stress that will need more time to heal the longer it goes. Sleep timing is underrated but it is just as important as quality and amount.

Err yeah they do? That's 'a night out', 'going out for drinks', 'night on the town', etc.

Sort of get the point, but not a brilliant analogy ;)

I think the analogy holds if you consider all these behaviors as negative behaviors which they are.

But you're right, people do say it so he's wrong. You could rephrase it as going on a bender and not eating/drinking as healthy is probably just as bad as lack of regular sleep.

I've walked myself into a circle. You're right

> Sleep regularity was a stronger predictor of all-cause mortality than sleep duration, by comparing equivalent mortality models, and by comparing nested SRI-mortality models with and without sleep duration (p = 0.14–0.20). These findings indicate that sleep regularity is an important predictor of mortality risk and is a stronger predictor than sleep duration.

Not totally disagreeing with you, but this indicates that it is _more_ important than the latter two when concerned with all-cause mortality.
