Researchers from Iowa State University discovered well-rested individuals reported feeling less angry and frustrated compared to those who had their sleep restricted.
Using a combination of sleep diaries and laboratory experiments, the scientists tracked more than 200 university students over the course of one month analysing their sleep, daily stresses and their feelings of anger. They found that those who reported a restful night of sleep were less likely to feel rage the next day.
They also conducted a further experiment on 147 people. Participants were either assigned to maintain their regular sleep schedule or were told to restrict it by five hours over two nights.
That experiment found that those who had a decent night sleep adapted better to noisy situations the following day compared to those who were sleep-deprived as they found more frustration and rage after not getting enough shut-eye.
