Sleeping seven to eight hours a night linked to taking fewer sick days

The researchers calculate that if insomnia, apnea and other kinds of sleep disturbances were eliminated, the total cost of worker sick days could be cut by 28 percent. “Previous studies have already shown associations between insomnia and sickness absence and there is some evidence regarding the association between sleep duration and sickness absence,” said lead author Tea Lallukka, a special researcher at the Finnish Institute of Occupational Health in Helsinki. The participants answered questions about their sleep disturbances, insomnia symptoms, daytime sleepiness and the average hours of sleep they got per 24 hours and had medical exams to detect mental or physical illnesses. Taking age into account, men who reported frequent insomnia symptoms had more than 10 sick days per year, compared to five absences for men who never or rarely had symptoms.
