The referenced study [1] showed that taking people out of their regular sleeping patterns had detrimental effects, which is a surprise to nobody. It did not test for the effects of different habitual sleep patterns! Participants were required to engage in one of a variety of different sleep patterns over up to 11 nights, with no consideration given to their normal preexisting sleep pattern. Our bodies adjust to different behavior over time, and it's only after the adjustment that you can begin to meaningfully compare and contrast different behaviors. Imagine you take random people and require they start running 4 miles a day with no consideration given to the preexisting patterns of physical activity! Well it'd certainly give the media their clickbait of the day as they 'discover' running is bad for you.
