Wow, what a contrast to this study of 36 people. Personally I feel that it's a bunch of placebo but a bunch of people I know swear by it. Nevertheless it's much harder to convince people to do what's more efficient compared to what _feels_ better when it comes to sleep. I for one feel much better if I wake up 7am sharp every day but it doesn't not feel that way naturally.

  It's not necessarily a placebo though right? I think 'catch-up' just isn't very well defined. I can be short of sleep and feeling awful each day of the working week, and then sleep in at the weekend and feel good that day relative to the last five. Have I 'caught-up'? Or does catching up mean negating long-term side-effects of sleep deprivation?

    > Have I 'caught-up'? Or does catching up mean negating long-term side-effects of sleep deprivation? This is the issue, and it's why the person who titled this article ought to be ashamed. We know sleep-deprived people sleep extra if you let them, in amounts predicted by their sleep deprivation. We know the recovery sleep produces better results on a bunch of metrics than getting ~8 hours without extra recovery time. We also know that they don't make up lost sleep hours one-to-one; they add a few hours over a few days then return to baseline, and the fraction recovered declines as the amount of deprivation rises. So.. what does all of that mean? I know my athletic performance responds to recovery sleep; I've seen studies saying cognitive performance does too. Does insulin sensitivity recover fully? (The author's past work finds "sorta".) Does that recovery provide a better baseline when deprivation starts again, or does it just shift to a new target level regardless? (This implies it just moves to the lower level.) How about the same two questions for memory? For muscle and aerobic exercise? And then: does time with recovered functioning correct long-term damage, mitigate it, or just stop worsening it? Is the short-term "elevated amyloid plaque levels" result actually tied to Alzheimer's, or do they just share a mechanism? Summarizing a one-weekend insulin sensitivity result as though it settles 50 different questions sharing a broad label is ridiculous.
