WASHINGTON D.C.: People who are the most optimistic tend to be better sleepers, a study of young and middle-aged adults found.
More than 3,500 people ages 32-51 were included in the study sample. The participants included people in Birmingham, Alabama; Oakland, California; Chicago; and Minneapolis.
The research was led by Rosalba Hernandez, a professor of social work at the University of Illinois.
“Results from this study revealed significant associations between optimism and various characteristics of self-reported sleep after adjusting for a wide array of variables, including socio-demographic characteristics, health conditions and depressive symptoms,” Hernandez said.
