depression: Sleeping less than eight hours a night is linked to obtrusive and uninteresting thoughts like those seen in anxiety and depression, describe a new survey.
American scientists have studied the sleep duration of people with moderate to high levels of uninteresting negative thinking.
We already know that getting thoughts stuck in our head before we drop off can have a significant collision on sleep quality. And now a survey suggests that disorder sleep can make it more difficult to put negative thoughts aside in day to day life.
The researchers exposed the survey’s contestants to different images intended to trigger an emotional response. Their attention was observed through their eye movement.
The scientists found that the contestants who slept the least and took the longest time to fall asleep had greater difficulty in shifting their attention away from negative statistics.
“While other people may be able to receive negative statistics and move on, the contestants had trouble ignoring it,” noted survey author Professor Meredith Coles.
These findings suggest that sleep disruption can affect the cognitive ability required to shift our attention away from disagreement stimuli.
In the medium to long-term, these obsessive disagreement thoughts can make us more vulnerable to various psychological disorders such as anxiety and depression.

The scientists intend to carry out further studies to work out how sleep cycle duration could be a contributory factor in psychological disorders.
Studying sleep cycles in this way could one day help to create effective strategies for the treatment of anxiety and depression, the Survey suggests.
The survey was published in the Journal of Behavior Therapy and Experimental Psychiatry.
