To keep morale up and prevent unexplained anger, researchers recommend getting a good night’s sleep. A simple solution to better manage your emotions.

Everything annoys you? Do you feel irritated at the slightest annoyance? Science may have a solution to help you feel better. No question of drugs or long therapies, researchers have a much easier remedy to implement immediately.

Indeed, to get better, all it would take is … a good night’s sleep. As part of this study, researchers analyzed data from 202 students. All of them reported on their sleep quality, stressors and anger for a whole month. Preliminary results show that participants feel more angry on the days following nights with less sleep.

Sleep well to be in a good mood

To supplement these results, the research team also conducted a laboratory experiment with 147 people. During this study, participants were selected at random. Some had to maintain their sleep schedule on a regular basis and others had to restrict their sleep at home by about five hours over two nights. The researchers then assessed the anger of the participants when exposed to loud noise. The science team found that those who slept the best adapt to noise the best and exhibit the least anger. Conversely, those who slept less well showed greater anger than others. According to the researchers, sleep loss can therefore interfere with participants’ emotional adjustment.

“The findings are important because they provide strong evidence that sleep restriction increases anger and increases frustration over time,” said Zlatan Krizan, PhD in Personality and Social Psychology and Professor of Psychology at Iowa State University in Ames, Iowa. He continued: “In addition, the results of the daily journal study suggest that such effects are reflected in everyday life, with young adults reporting more anger in the afternoon on days when they slept less. ”. In light of these results, the authors noted that the results underscore the importance of considering specific emotional responses such as anger and their regulation in the context of sleep disturbance.
