It's easier for students. When I'm on that schedule, I wake up around 7 a.m. (naturally), nap around 4:30 or 5 p.m., and go to bed around 1 a.m. It's maintainable when I don't have regular late-afternoon meetings, and very helpful during "death march"-type projects because it feels like having two days in one.
As a side effect, dinner shifts later in the day. This is noticeable in places where siestas are common, like Spain -- early breakfast, nothing happening in the mid-afternoon, and then everyone emerges for dinner and night life around 8-10 p.m.
