The Personality Trait Linked To Perfect Sleep
The trait can be increased using psychological exercises.

Optimistic people tend to sleep the best, research finds.
People who are hopeful about the future were 78 percent more likely to report very good quality sleep.
Positive people also reported getting a good amount of sleep: six to nine hours per night.
Finally, optimists were much less likely to report any symptoms of insomnia or daytime sleepiness.
The reason optimism is linked to better sleep could be that it promotes positive coping.
People who cope adaptively with stress in life tend to seek support from others, eat properly, exercise regularly and anticipate stressful episodes.
The good news is that optimism is not fixed in stone.
Exercises such as visualising your ‘best possible self‘ have been shown to increase optimism.
Inadequate sleep is linked to an increased risk of many chronic diseases, said Professor Rosalba Hernandez, the study’s first author, said:
“The lack of healthy sleep is a public health concern, as poor sleep quality is associated with multiple health problems, including higher risks of obesity, hypertension and all-cause mortality.
Dispositional optimism — the belief that positive things will occur in the future — has emerged as a psychological asset of particular salience for disease-free survival and superior health.”
The study included 3,548 people across three large US cities.
They completed measures of optimism and reported on their sleep quality.
People who are optimistic tend to agree strongly with statements like “I’m always optimistic about my future” and strongly disagree with statements like “I hardly expect things to go my way.”
Some participants were brought into the lab to have their sleep quality directly measured.
Professor Hernandez explained what the study found:
“Results from this study revealed significant associations between optimism and various characteristics of self-reported sleep after adjusting for a wide array of variables, including socio-demographic characteristics, health conditions and depressive symptoms.”
Optimism promotes adaptive coping, said Professor Hernandez:
“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.”
The study was published in the journal Behavioral Medicine (Hernandez et al., 2019).
What Your Bedtime Reveals About Your Personality (M)
Your bedtime routines could reveal a lot about your personality traits, such as conscientiousness and the propensity to take risks.
2 Personality Traits That Predict Your Lifespan
People with this personality trait tend to have better health habits and more stable jobs and marriages.
People with this personality trait tend to have better health habits and more stable jobs and marriages.
People who are conscientious and careful live the longest lives, research finds.
Conscientious people tend to be self-disciplined and they aim for achievement.
Two aspects of conscientiousness have the strongest link to a long life:
- A preference for order,
- and an orientation towards achievement.
Careful people are also less likely to smoke or drink and experience lower levels of stress.
In more bad news for people trying to enjoy their lives, happiness seems to have little connection with a long life.
The reason is that cheerful, laid-back people tend to be more careless about their health.
Persistent and conscientious people, though, get that check-up.
The conclusions come from an analysis of 20 different studies which included over 8,900 people in many countries.
Being more conscientious was consistently linked to living a longer life.
It is probably because conscientious people tend to have better health habits and more stable jobs and marriages.
Conscientiousness is one of the five major aspects of personality, along with agreeableness, extraversion, openness to experience and neuroticism.
Professor Howard S. Friedman, the study’s co-author, said:
“The major finding is that this conscientiousness aspect of personality is indeed reliably predictive of mortality risk across studies.
This seems to be as important as most commonly assessed medical risk factors, few of which are psychological.”
If you are not that conscientious, there is still hope, said Dr Margaret L. Kern, study co-author:
“There is some evidence that people can become more conscientious, especially as they enter stable jobs or good marriages.
We think our findings can challenge people to think about their lives and what may result from the actions they do.
Even though conscientiousness cannot be changed in the short term, improvements can emerge over the long run as individuals enter responsible relationships, careers and associations.”
The study was published in the Journal of Personality (Kern & Friedman, 2008).
