Interesting study, bad title. The claim is that getting 6 hours per night is as bad as not sleeping for two nights. The other interesting aspect is that the people who got six hours night after night underreported their fatigue. That fits with my experience. Several years ago, I started missing out on a lot of sleep (young kids, trying to learn programming while working a full time job). When I finally started sleeping enough, I felt like I was fully awake for the first time in years. Before, I would notice I was truly exhausted, and sleep more for a day or two, but I was never actually catching up, just taking the worst of the edge off.
