Scientists from Auburn University have found that feeling happy throughout the day can trigger restless sleep. there was work published in Child Development magazine.
323 young people aged approximately 17 participated in the study. During the study, the scientists collected data on teens’ sleep for a week using smartwatches that recorded limb movements. They also rated their sleep quality each morning and their mood during the day each evening.
The results showed that feelings of happiness were associated with restless sleep. Negative mood was associated with more time spent sleeping and more restful sleep. However, participants’ subjective assessment showed that good mood was accompanied by high sleep quality and negative mood was accompanied by low sleep quality.
In the future, scientists will repeat the study with teenagers of different ages.
