Study finds that low productivity in the workplace could be a sign of Excessive Daytime Sleepiness

DEPM's Winda Ng and Dr Rosanne Freak-Poli  have co authored a study which has found that excessive daytime sleepiness (EDS) is potentially an important contributor to lower productivity and poorer mental health in the workplace. The study also suggests that workplace health programs aimed at improving diet and body weight may help alleviate EDS.

According to the study, EDS refers to a symptom of increased sleep propensity, when one’s intention is to remain awake. Since the late 1960s, EDS has been viewed as a serious medical condition and research in this area has started to develop. The recognition of its importance is likely to be related to the increasingly apparent consequences of EDS; such as increased risk of travel accidents and work-related injuries, decreased quality of professional and academic performance, and increased rate of work absenteeism.


In the study of a mixed population of employed Australian workers, the prevalence of EDS was estimated to be 16 percent. Several factors were found to be associated with EDS and, including age, higher BMI, worse dietary habit, and poorer mental health status.
