The report is interesting and it isn't surprising that partial sleep deprivation results in a cognitive deficit. I'd be more interested in understanding the long-term effects of insufficient sleep. Is the cognitive deficit a temporary problem that goes away after a few days (or more of) sufficient sleep OR will sustained lack of sleep (over a long period) result in a long-term problem that persists even after the subject begins to sleep sufficiently.

  weird. I've had some gray (at least, some I and others could notice) since I was 18 (and quite a lot all these years later). One of my brothers is 15 and has some gray. It's not really saying why the hydrogen peroxide builds up though. :/

In rats, at least, absolutely no sleep over something like a month resulted in death. That scenario was completely unnatural, though. They had to be kept awake with electric shocks or something, so I don't think people are physically capable of going without sleep for that long, unless someone is tormenting them.

The problem with this is the search terms are pretty difficult to get right and requires a lot of sifting. Some studies concern themselves with studying "sleep deprivation" as in total sleep deprivation (see the sibling comment in this thread talking about rats). In reality, you (and me) are looking for long-term effects of sleep deprivation, where deprivation = 5-6 hours regularly, 4 or less occasionally. Unfortunately, you can't just Google that. Anyone know of any articles that target this bracket of sleep deprivation (and not something more extreme)?

> I'd be more interested in understanding the long-term effects of insufficient sleep. I will confidently guess it involves more infections/sick-days. More zits, and general inflammation. Higher cortisol/stress/angst. Higher rates of gastro-intestinal complaints (IBS, heart-burn). If I skimmed the article correctly it measured ability to concentrate for a short time exclusively and ignored these others metrics.
