There's some truth to that. We Muslims still have to get up at sunrise, and we're encouraged to maybe take a 30-minute nap around noon. And during those long nights, you'd get up after 3 hours and stay awake for another 1 or 1.5 hours. I've never bought into that whole idea of sleeping 8 hours straight that most fitness enthusiasts promote. After 8 hours of sleep—if I even manage to do that—my brain feels like mush.
