Such workers either experience shorter sleeping hours (fewer than six hours a night) or longer sleeping hours (longer than nine hours), emphasizes a study from the Perelman School of Medicine at the University of Pennsylvania.
Previous studies have shown that people who report short or long sleeping habits are more likely to have health problems over time. These might include weight gain, heart disease, and diabetes. The new study suggests that unhealthy sleeping habits due to professional requirements could detrimentally affect health.
According to the research team, possible explanations for the findings include high demand of longer working hours, not allowing sufficient sleep at night. Moreover, job-related stress is keeping people awake till late at night.
