Sleep Restriction May Amplify Anger and Frustration, Says Study
News 18Feeling angry these days? For the study, published in the journal SLEEP, the research team analysed daily diary entries from 202 college students, who tracked their sleep, daily stressors, and anger over one month. “The results are important because they provide strong causal evidence that sleep restriction increases anger and increases frustration over time,” said study author Zlatan Krizan, a Professor at the Iowa State University in the US. “Moreover, the results from the daily diary study suggest such effects translate to everyday life, as young adults reported more anger in the afternoon on days they slept less,” Krizan added. “Together, these results provide compelling evidence that lost sleep amplifies anger in both the laboratory and everyday life,” the study authors wrote.
