As practical consideration, most of the world understands your sleep cycle.
Yet if you tell people that you actually need those eight hours of sleep to function properly you get ridiculed. Everyone expects you to function just fine on 5-6 hours per night, any more is seen by a lot of people as being a bit "lazy" (either going to bed "too early" or "sleeping in").
I'm not ashamed to say that anything less than seven hours per night on average completely messes me up, I can feel it the moment I wake up, I need more sleep or I will function poorly (a few months ago I wound up only getting 4-5 hours per night for a full week, by Friday I was completely useless at work, just staring at my monitor trying to force my brain to do work).
