This program of research included analysis of diaries and laboratory tests. Researchers analyzed the daily diary entries of 202 college students who tracked their sleep, daily stress, and anger over a month. Preliminary results of the study suggest that all of those students experienced more anger on days they had less sleep than on normal days.

The research team also conducted a lab experiment involving 147 community residents. Participants were randomly assigned 2 types of tasks without following any pattern. 1st- either maintain your sleep schedule or 2nd- restrict your sleep to around 5 hours in 2 nights by staying at home. After this manipulation, all subjects were exposed to an arousing or irritating noise and during this time their anger was rated.

After this experiment, it was found that all the people in the study who slept well adjusted to the noise and after 2 days they were less angry or angry. In contrast, sleep-restricted participants showed significantly more anger towards the aversive sound or noise. This suggests that sleep deprivation also reduced the emotional adaptation of those in a frustrating situation. Another related experiment was conducted in which people reported anger after an online competitive game. Similar results were found in that too.

Zlatan Krijn, Professor of Psychology at Iowa State University in the US, says, "The results of the study are important because they provide strong evidence to suggest that sleep interruption or loss increases anger and increases frustration and disappointment over time." Furthermore, the results of the daily diary study suggest that such effects translate into everyday life, as the college students in the study reported feeling angrier in the afternoon on days when They slept less."
