Researchers at the University of British Columbia found that individuals who work nights and rotating shifts are nearly twice as likely to be injured on the job. Their study, published in the current issue of the Scandinavian Journal of Work, Environment and Health, examined statistical data on more than 30,000 people.
It found that while the overall rate of work injuries went down from 1996 to 2006, there was no decline for night-shift workers. The author found that the disruption of normal sleep patterns can cause drowsiness or fatigue, which can lead to workplace injuries.
