But it still has a negative effect on mood It is believed that sleepy people are more angry than those who have given enough time to sleep. As scientists have found out, this is not so. Discuss in a row at the WSU Sleep and Performance Research Center Elson S. Floyd College of Medicine. On the first night, the subjects were allowed to sleep normally, after which they were given a set of baseline tests to judge their mood. At the next stage of the study, the participants were divided into two groups – 40 people needed to spend a sleepless night, while the remaining 20 people slept peacefully during this time. The tests were then re-run at different intervals.
Despite the fact that a night without sleep affected people's mood, their performance on tests measuring their ability to process emotional words was found and images have not changed.
“People are less happy with sleep deprivation, but this does not affect how they handle emotional stimuli in their environment,” she said research author.
