Researchers from the University of Chicago compared the levels of loneliness 95 adults in rural South Dakota, USA with the results of measurements of sleep cycles. No individuals who are socially isolated, but the perception of loneliness varies.
Higher loneliness scores associated with high levels of uninterrupted sleep at night. Total sleep and daytime sleepiness did not affect.
"Not only because the individual who is very lonely to be lack of sleep. The relationship between loneliness and anxiety sleep occurs in a variety of perceived relevance," said lead author Lianne Kurina, PhD, of the Department of Health Sciences at the University of Chicago as quoted from medicalxpress.com, Tuesday ( 11/01/2011).
"Loneliness associated with adverse health effects. We want to explore the theory that sleep may be influenced by feelings of loneliness. We found that loneliness does not change the total number of individuals sleeping, but woke indvidu more often throughout the night," he said.
This finding is similar to previous research, published in 2002 by the American Psychological Society that compares loneliness to the quality of sleep reported by students. The students who feel lonely more often disturbed her sleep at night.
The similarity between this study helps to show that loneliness and social isolation are two different concepts. Researchers argue that loneliness reflects the perceived social isolation or the feeling of being an outcast, ie the gap between the desired relationship with the actual social relations which are often painful.
"We all seem to rely on feeling safe in a social environment to be able to sleep soundly. The results of this study could provide further understanding about how these factors affect the social and psychological health," concluded Kurina.
