Are you struggling to sleep? Try being more optimistic! A recent study has found that those with a more optimistic disposition had significantly better odds of getting better quality sleep.
More than 3,500 people ages 32-51 participated in the 2019 study, which measured optimism by asking participants to assess 10 statements using a 5-point scale.
To measure their sleep, participants reported on their sleep twice over a period of five years and rated their sleep quality and duration during the previous month. The survey assessed their symptoms of insomnia, difficulty falling asleep, and the number of hours of actual sleep they obtained each night. Some participants also wore activity monitors that collected data on their sleep duration, percentage of time asleep and restlessness while sleeping.
Participants with higher optimism scores were more likely to sleep for 6-9 hours each night and 74% less likely to have insomnia.
Lead author Dr Rosalba Hernandez, from the University of Illinois, speculated on what could explain their findings: "Optimists are more likely to engage in active problem-focused coping and to interpret stressful events in more positive ways, reducing worry and ruminative thoughts when they're falling asleep and throughout their sleep cycle."
