People who work long hours and have long commutes to their jobs may be more likely to have sleep problems and not get enough exercise, a new study suggests. Researchers in Sweden carried out the study. They looked at people who work more than 40 hours a week and commute more than half an hour each way on an average day. The researchers found that those people had a 25-percent higher risk for having an inactive lifestyle and a 16-percent higher risk of having sleep problems. Jaana Halonen is the study’s lead writer. She is with Stockholm University and the Finnish Institute for Health and Welfare in Helsinki, Finland. She said sleep problems may happen from “lack of time for stress-releasing activities and relaxation.” She also said people with long workdays and a long commute may be too tired to be physically active.
