How CEOs Optimize Their Sleep Routine

Welcome to the CEO Diet, a monthly series in Bloomberg Businessweek in which executives from around the world tell us how they manage their time in and out of the office. Among the topics they’ve discussed: their favorite exercise routines, fashion uniforms, ways to win the weekend and nonalcoholic drinks.

This month, the question for the big boss is one that preoccupies almost everyone I know: How do you optimize sleep? There’s a lot of appreciation for nighttime rituals, from vitamin regimens to micro meditation sessions and half-hour baths. But there’s also an appreciation for just falling asleep, the old-fashioned way.
