Skip the early morning jog and sleep in, say research scientists at the German University of Fulda.
Much like hibernating bears, people live longer if they sleep eight to nine hours a night, take naps and avoid long work hours and extreme exercise, say the researchers.
Not that sloth should be your motto, they hasten to add. You simply need to limit your stress. If you exercise regularly – for example, for an hour or more seven days a week without giving your body a chance to rest between workouts – your adrenal glands become overworked, thus weakening your immune system. Indeed, marathon runners and workaholics have shorter-than-average life spans, the researchers found, while siesta-loving Italians live longer.
