Studies have asked large numbers of people how many hours of sleep they actually average and followed the health of these people over decades. That's worrisome, because the average person has worse health outcomes including more obesity, diabetes, and heart disease, and shorter life if he or she sleeps less or more than these ranges, on average.
The important word is average. Some people who average more or less than these hours of sleep remain in excellent health. Perhaps they have different genes.

You can imagine how difficult it would be in the real world to conduct a study like that. Why do we need this much sleep?
