My sleep cycle is fairly standard, most of the time 11:00PM-7:30AM ... I can manage 1AM-9AM ~twice a week without too muhch of a performance hit, and if I am getting sick, I can usually mitigate by sleeping 9PM-8AM. When tired I did experiment with having a siesta (~45 min rest at 14PM), but the logistics are weird (i.e. having a place to lay down, eye-mask for darkness, ear-plugs or withe-noise generator ...) My best productive hours are weird :D 7AM to 10AM and 7PM to 10PM ... this unfortunately isn't really compatible with having any sort of social life :D My wife is more of a night-owl, fine going to sleep at 2AM but not feeling rested unless she was asleep between 8AM-10AM, which is tricky with our kid going to kindergarden in mornings. If she is tired enough, she can manage the similar trick of being in bed before 10PM to avoid getting sick.
