Improved Sleep May Reduce Time Away from Work.
It appears that absence from work due to sickness is related to a lack of good sleep. A new study has found that people who regularly get seven to eight hours of uninterrupted sleep per night are less likely to be absent from work due to an illness. The study further noted that the risk of being absent from work due to sickness for 10 days or more rose significantly among people who slept less than six hours or more than nine hours a night. The researchers note that the optimal sleep duration each night for adults is 7 hours 46 minutes for men and 7 hours 38 minutes for women.
