If you’re a person who thinks a rainy day is good for the flowers, instead of dreary, you could be adding years to your life. If you’re someone who thinks you’ll soon be feeling bright and lively when you’re down with a fever, instead of looking up all the deadly viruses you might have contracted, you have a good chance of living to 85 or older.
That’s because a new study found that optimism may contribute to longevity. Researchers at Boston University School of Medicine and the Harvard T.H. Chan School of Public Health found that “optimism is specifically related to an 11-to-15 percent longer life span, on average, and to greater odds of achieving ‘exceptional longevity,’ that is living to the age of 85 or beyond.”
The results published in the journal PNAS show that the improved longevity is not related to socioeconomic status, health conditions, depression, social interaction or even health behaviors such as smoking, diet or alcohol use.
The most obvious reason to adopt an optimistic attitude is to help keep depression at bay. The negative effects of depression such as not eating a healthy diet, avoiding physical activity and becoming isolated contribute to poor health.
The researchers speculate that just expecting the best to happen might make people more motivated to make good choices, especially about health. People with a positive outlook might refrain from smoking, choose healthier foods and exercise more regularly.
In a report from Harvard Medical School, a study of more than 300 patients who had coronary artery bypass surgery found that optimists were half as likely as pessimists to have to return to the hospital.
In as separate study of 300 angioplasty patients, pessimists were three times more likely than optimists to have a heart attack or require repeat angioplasties or bypass operations.
Even people who tend to be gloomy and expect the worst can develop a sunnier outlook on life, according to Natalie Dattilo, a clinical health psychologist at Brigham and Women’s Hospital in Boston.
“We can begin to uncover systems of beliefs and assumptions people are making about themselves and their lives and we can begin to change those,” said Dattilo.
When a negative outlook shows up, a person can consciously learn to shift to a more positive perspective.
Optimism is not the same as happiness. Life is going to bring challenges and hard times. The difference between a person with an optimistic and pessimistic outlook is how they cope, especially then things get tough. Here are some ways to increase optimism:
