Workers who experience insomnia and other sleep-related problems are less productive during the workday, hint results of a new study, according to Medscape.

“If you take someone with insomnia and someone without insomnia, put them in the same life, the one with insomnia is losing twice as much productivity,” senior author Michael Grandner, PhD, director of the Sleep and Health Research Program and assistant professor of psychiatry at the University of Arizona College of Medicine in Tucson, told Medscape Medical News.

Sleep should be considered an important element in workplace health, Grandner and colleagues say.

The study was presented here at SLEEP 2018: 32nd Annual Meeting of the Associated Professional Sleep Societies.
