Night Shift Workers More Likely to Drive DrowsyJanuary 18, 2016
A recent study undertaken by Brigham and Women’s Hospital (BWH) found that night shift workers are 37.5 percent more likely to crash while commuting home than they would be if they had not worked a night shift. The study, which was published in Proceedings of the National Academy of Sciences, compared driver performance after working a night shift to the performance of the same drivers, at the same time, but after a good night’s sleep. This study confirms that drowsy driving can be extremely dangerous for everyone on the road.
For this study, 16 night shift workers completed two, two-hour driving sessions. Prior to the first session, the drivers slept about 7.6 hours the night before, with no night shift work. Prior to the second session, drivers were tested immediately following a night shift. Both sessions were tested at the same time of day. Researchers measured brief micro-sleep episodes with an EEG, and partial eyelid closure with slow eye movements, which indicate that a person is transitioning from a wakeful state to sleep.
According to the author of this study, Charles A. Czeisler, PhD, MD, FRCP and Chief of the Division of Sleep and Circadian Disorders at BWH, during the study, night shift workers were crossing over the middle line and having other safety and alertness issues. Forty percent of the driving trips had to be terminated early because participants failed to maintain safe control of their vehicles. More than half of the drivers who participated in the study self-reported that they nodded off behind the wheel at least once a week on their way home from work. The results of the study confirmed this.
In addition to finding that participants showed increased drowsiness, decreased performance and an increased risk of near-crashes, the study found that the risk of micro-sleep episodes increased after driving more than 30 minutes. The study further found that even veteran night shift workers were vulnerable to these risks. Researchers claim that night shift workers are working against their natural circadian rhythms and can’t sleep as well during the day to make up for lost sleep, further exacerbating the cycle of drowsy driving.
According to Dr. Czeisler, these results explain why night shift workers are involved in so many more car accidents than day workers. He advised all night shift workers to seek an alternate form of transportation every night after work. However, in reality, this is probably not feasible for most night shift workers. Bus and train services may not run during the early morning hours when many night shift workers need transportation. And many people work overnight in remote areas where there is no access to public transportation. Most cannot afford to take a taxi every day, especially those with a long commute.
