Led by Bryce Hruska, assistant professor of public health in the Falk College, investigators looked at the sleep patterns of 79 EMS workers from Central New York. The results were published in Sleep Health: Journal of the National Sleep Foundation. They found that EMS workers who typically experienced poorer sleep quality reported greater anger levels. Workers who routinely experienced poor sleep quality reported anger levels that were 18 to 35 percent higher compared to workers receiving fair sleep quality. Regardless of their typical sleep quality, days when workers experienced poorer sleep than usual were characterized by higher levels of anger. On a day when a worker experienced poorer sleep quality than usual for them, their anger levels were five percent higher on that day regardless of their typical sleep quality. Read more.
