In a new Harvard University study, women who had an optimistic outlook were less likely to die from several causes, including top killers like heart disease, cancer, and infection. The study isn’t the first to make a connection between optimism and health benefits; other research has linked the positive-thinking personality trait to a lower risk of dying from [cardiovascular problems](http://news.health.com/2015/01/14/an-optimistic-outlook-may-be-good-for-your-heart/), for example. But this is the first time it’s been associated with protection from other major illnesses. **_Read more:_** [_Why Heart-Healthy Choices Are Extra Important for Women With Migraines_ ](http://www.realsimple.com/health/preventative-health/heart-health/migraines-linked-to-increased-stroke-risk/?xid=time-rs) To reach these conclusions, researchers analyzed data from more than 70,000 women enrolled in the nationwide Nurses’ Health Study. The women answered survey questions about their health and mental state—including their outlook on life during uncertain times—and were followed for about eight years total. During that time, women who ranked in the top quarter for optimism had a [29 percent lower risk of dying](http://dx.doi.org/10.1093/aje/kww182) from any cause during the follow-up period, compared with those in the bottom quarter. Specifically, they had a 52 percent lower risk of dying from infection, a 39 percent lower risk of dying from stroke, a 38 percent lower risk of dying from heart or respiratory disease, and a 16 percent lower risk of dying from cancer. “While most medical and public health efforts today focus on reducing risk factors for diseases, evidence has been mounting that enhancing [psychological resilience](https://www.eurekalert.org/emb%5Freleases/2016-12/htcs-om120216.php) may also make a difference,” said co-lead author Eric Kim, PhD, research fellow at the Harvard T.H. Chan School of Public Health, in a press release. “Our new findings suggest that we should make efforts to boost optimism, which has been shown to be associated with healthier behaviors and healthier ways of coping with life challenges.” **_Read more:_** [_Happy People Make Their Spouses Healthier_](http://www.realsimple.com/health/mind-mood/happy-people-make-their-spouses-healthier/?xid=time-rs) This study was not able to prove a cause-and-effect relationship, and of course it would make sense that healthier people might also be more optimistic—or that optimistic people would take better overall care of themselves. But the researchers controlled for these scenarios as much as possible, by excluding participants who had an illness at the start of the study, or who died within the first two years. And even after controlling for health conditions, depression, and healthy behaviors—such as eating a healthy diet, exercising regularly, and not drinking excessively or smoking—the most optimistic women still had a 9 percent reduced risk of dying, compared to the least optimistic. This suggests that, in addition to encouraging healthy behaviors, optimism may directly affect our biology, says Kim. Exactly how is unclear—but previous studies offer some potential clues, suggesting that the trait is associated with benefits such as healthier cholesterol, lower levels of inflammation, stronger immunity, and a slower rate of cellular aging. **_Read more:_** [_How to Reduce Inflammation_](http://www.realsimple.com/health/how-to-reduce-inflammation/?xid=time-rs) Perhaps the best news is that optimism is something we can all practice. Even if you’re naturally a glass half-empty type of person, studies show that [a positive mindset can be learned](http://www.realsimple.com/health/mind-mood/emotional-health/optimistic-kids) and cultivated through [relatively simple exercises](http://www.realsimple.com/work-life/life-strategies/how-to-be-optimistic). One example could be “having people write down and think about the best possible outcomes for various areas of their lives, such as careers or friendships,” says co-lead author and research fellow Kaitlin Hagan, PhD. “Encouraging use of these interventions could be an innovative way to enhance health in the future.” ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/4595633/optimism-live-longer/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/4595633/optimism-live-longer/"},"headline":"How Your Outlook Affects Your Lifespan","datePublished":"2016-12-08T19:19:09.000Z","dateModified":"2026-02-23T02:13:09.316Z","description":"Even more reason to be optimistic","url":"https://time.com/4595633/optimism-live-longer/","keywords":["Mental Health/Psychology","Mental Health"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blt785a92ccdc4715e8/6988604b524fc06711df4294/aging-health-illo.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Amanda MacMillan / Real Simple"}],"articleSection":"Health","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blt785a92ccdc4715e8/6988604b524fc06711df4294/aging-health-illo.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"TIME.com stock health aging","caption":"TIME.com stock health aging","creditText":"Illustration by Sydney Rae Hass for TIME","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/health/","name":"Health"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/mental-healthpsychology/","name":"Mental Health/Psychology"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/4595633/optimism-live-longer/","name":"How Your Outlook Affects Your Lifespan"}}]}] ```
