Workers with nontraditional schedules are burdened by sleep-related health problems and poor metabolic health, according to a new report. Shiftworkers in the study were significantly more likely than traditional schedule workers to be overweight (47.9% vs. 34.7%). They also experienced more sleep problems such as insomnia (23.6% vs. 16.3%), insufficient sleep (53.0% vs. 42.9%), or excessive wake-time sleepiness (31.8% vs. 24.4%).
