Sleep Quality Linked to Rumination

Jacob Nota and Meredith Coles from the Department of Psychology at Binghamton University in the US have made some interesting discoveries regarding sleep duration and timing. Their research confirmed what others had already noticed, that rumination (repetitive negative thinking) was associated with reduced sleep duration. In addition to this, they found that the timing of sleep was also important. Individuals that reported later sleep and activity times also reported more repetitive negative thinking.

People that ruminate tend to suffer more from anxiety, depression, post-traumatic stress disorder and obsessive-compulsive disorders. For those that sleep too few hours, increasing sleep has already been found to decrease symptoms of psychopathology. Further efforts to get to bed earlier may provide even more benefit.

These recent findings highlight the importance of sleep on health.
