Not getting enough sleep amplifies the feeling of anger

Researchers carried out two experiments that showed a direct relationship between less sleep and increased anger.

If you have been feeling unusually angry lately, it may be due to a lack of a good night’s sleep.

This is what a study by researchers at the American Academy of Sleep Medicine suggests. They found that anger is directly linked to sleep quality.

The scientists monitored daily diary entries from 202 college students, tracking their sleep, stress, and anger over a month. The results showed that the subjects reported feeling more anger after nights when they slept less than usual.

In addition to this experiment, the team conducted another test involving 147 people. Participants were randomly divided into two groups: one maintained their regular sleep schedule and the other slept only five hours over two nights.

After that, the participants were exposed to an irritating noise to assess their anger.

As a result, the scientists found that individuals who slept more adapted to the noise and reported less anger after two days.

In comparison, those who slept less felt more anger in response to the noise, suggesting that not getting enough sleep impairs emotional adaptation to frustrating circumstances.

“The results are important because they provide strong causal evidence that sleep restriction increases anger and increases frustration over time,” said study leader Zlatan Krizan, a professor of psychology at Iowa State University in Ames. “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.”

The study results were published in the journal Sleep.
