Habit: Sleeping Late on Weekends
Good News: Though going to bed at the same time and waking at the same time every day is the best way to feel rested, that's easier said than done. And it turns out there's a more realistic solution to combat the consequences of sleepless nights: A study in the journal Sleep suggests that "sleep banking"—clocking more hours of shut-eye in anticipation of a sleep-deprived night—may lessen fatigue. When subjects snoozed ten hours per night the week before they could squeeze in only three hours of sleep, they experienced fewer impairments in cognitive performance and alertness than those who clocked a steady seven hours prior to sleep deprivation.
