Compared to individuals who mostly worked during traditional daytime hours, those whose careers featured a more volatile work schedule slept less, had lower sleep quality, and were more likely to report depressive symptoms at the age of 50.
The study suggests that erratic work schedules are associated with poor sleep, physical fatigue, and emotional exhaustion, leading to health vulnerabilities.
People with work patterns involving any degree of volatility and variability were more likely to have fewer hours of sleep per day, lower sleep quality, lower physical and mental functions, and a higher likelihood of reporting poor health and depressive symptoms at age 50.
