In order to sleep better, it is recommended to play sports regularly, avoid excitement after a certain time, or not use screens before going to bed. A new study says our behavior could affect our sleep quality: optimistic people will sleep better.
More than 3,500 participants
in Behavioral Medicine, the research team publishes the results of their work done with more than 3,500 participants between 2000 and 2006. They provided information about their sleep twice, 5 years apart. Everyone also answered a questionnaire where they had to express their level of agreement with a series of statements using a scale of 1 to 5, starting from strongly disagree to fully agree. Among the proposed phrases were "I don't expect things to happen the way I want" or "I'm always optimistic about my future."
The researchers then determined the level of optimism of each of them: at each point increase, sleep quality improved by 78%. According to their findings, the most optimistic participants were 74% less likely to suffer from insomnia and were more likely to have 6 to 9 hours of sleep. "Optimistic people tend to interpret problems in a positive way," says research director Dr. Hernandez, "it reduces anxiety and ruminations during sleep and during the sleep cycle."
