Work Time Is Largest Influence To Duration Of Person's Sleep

Work time is the primary lifestyle factor with the largest reciprocal relationship to a person's sleep time --- the more hours a person works, the less sleep that he or she gets, according to a new study. Short sleepers also spent more time engaged in education, household activities and, for very short sleepers, watching TV. Except for time spent watching TV, which increased with longer sleep times, all waking activities decreased with increasing sleep time.
