If there's one thing the world needs at the moment, it's active, vocal bullshit detectors.

I loved this article, because I have a dog in this fight. I am a natural short-sleeper and have been for my entire life. My mom reports that even as an infant I slept very little and never napped. And for my whole adult life (not counting when I was pregnant), 6-1/2 hours is apparently all I need; I wake up without an alarm clock at 5am feeling rested and never feel sleepy during the day.

But the mainstream view is that I may feel fine NOW, but severe consequences (dementia, cancer, early death, what have you) are coming for me down the road, and that everyone who isn’t getting the full 8 hours is damaging their health. But how do they know? Has anyone actually done a longitudinal study of happy and healthy natural short-sleepers, as opposed to people who do need 8 hours but sleep less because of stress or long work hours?

I am left wondering whether the 8-hours-of-sleep rule is like the dictum that we should drink 8 glasses of water and walk 10,000 steps per day. Both of the latter two numbers turn out to have been made up. Why should it be any different with sleep?
