Worrying excessively about the future, delving too much into the past, experiencing invasive thoughts … These are the symptoms of common psychological disorders, such as anxiety, depression or post-traumatic stress.
Previously, this battery of recurring bad vibes had already been linked to problems at bedtime, but now the results of a systematic study have just been published.
Jacob Nota and Meredith Cole, from Binghamton University (USA), subjected 100 young adults to a series of questionnaires and computerized tasks, in addition to asking them if they were more nocturnal or daytime. Thus, they observed that the volunteers who experienced negative thoughts more often went to bed later or spent fewer hours sleeping. It also seems clear that the mental "buzz" affects the quality of the night's rest.
Researchers therefore suggest that therapies for the disorders associated with these symptoms lead to dedicating a third of our lives to abandon ourselves to the arms of Morpheus.
