Loneliness Heart Disease, And Depression
November 1, 2011 by staff
Research suggests that walking around at night may be dependent on the socially isolated you think you are, not whether you are actually isolated from the people around you.
The authors of the U.S. say that loneliness has been linked to poorer health, such as high blood pressure and heart disease in women. It is believed that one reason is that people who feel disconnected from those around them do not sleep as well as their more sociable.
Researchers at the University of Chicago set out to determine whether loneliness is associated with fragmented sleep or not enough sleep.
They looked at 95 studies of adults from a close knit farming community in South Dakota. The participants, with an average age of under 40 years, asked if she felt lonely, depressed, anxious or stressed. They were also asked to assess how well it was thought that sleep at night and how they felt sleepy during the day.
Participants also wore a wrist actigraph for a week to accurately record the amount which turned in his sleep.
The results were adjusted to take into account factors such as age, sex, body mass index and risk of sleep apnea and whether a participant was depressed, stressed or anxious for reasons other than sleep loss.
Writing in the latest edition of the journal Sleep, the authors report that those who scored highest for loneliness were more likely to experience higher levels of sleep fragmentation. However, no relationship was found with duration of sleep.
The researchers also found that this effect does not depend on whether people were actually socially isolated, but based on whether they felt they thought they were alone.
The findings are similar to a 2002 study published by the American Psychological Society, in comparison to loneliness as students of the university to measure sleep quality. The students felt lonely, plus his sleep was broken up during the night.
The similarities between the studies help to point out that loneliness and social isolation are two different concepts, according to lead author Lianne Kurin. She says that loneliness reflects the gap between whether a person is socially isolated or not, and the relationships they crave.
“Whether you’re a young student at a major university or an older adult living in a rural community, we can all be dependent on a sense of security in our social environment in order to sleep well,” said Lianne Kurin in a statement. “The results of these studies could improve our understanding of how social and psychological factors” get under the skin and affect health. “
