How Lonely You Feel Could Impact Your Sleep

Feeling lonely at night? It just might be the cause of you not getting enough sleep.  According to a study from the Dept. of Health Studies at the University of Chicago; a cause for restless sleep or lack of sleep may be linked to how lonely a person is. Lead author Dr. Kurina, PhD. Says, "The relationship between loneliness and restless sleep appears to operate across a range of perceived connectedness.

In the study, Dr. Kurina and her co-researchers compared the degree of loneliness reported by a close-knit population of 95 adults in rural South Dakota by measuring their sleep cycles. Although none of the individuals were socially isolated, their perceived notions of loneliness varied, Higher loneliness scores were linked to significantly higher levels of fragmented and restless sleep. The total amount of sleep and the degree of daytime sleepiness were not impacted.

"Loneliness has been associated with adverse effects on health," Kurina said. "We wanted to explore one potential pathway for this, the theory that sleep -- a key behavior to staying healthy -- could be compromised by feelings of loneliness. What we found was that loneliness does not appear to change the total amount of sleep in individuals, but awakens them more times during the night."

These recent findings, - which appeared in the Nov. 1 issue of the journal SLEEP-were similar to a 2002 study published by the American Psychological Society.  It compared the loneliness reported by college students with their measured quality of sleep. The lonelier the students felt, the more their sleep was broken-up during the night.

The similarities among the studies help point out that loneliness and social isolation are two distinct concepts, Kurina said. Loneliness reflects perceived social isolation or feelings of being an outcast, the often-painful discrepancy between a person's desired and actual social relationships.

"Whether you're a young student at a major university or an older adult living in a rural community, we may all be dependent on feeling secure in our social environment in order to sleep soundly," Kurina said. "The results from these studies could further our understanding of how social and psychological factors 'get under the skin' and affect health."
