“This study tests one possible explanation, assessing if more optimistic people handle daily stress more constructively and therefore enjoy better emotional well-being,” said corresponding author Lewina Lee, Ph.D., a clinical psychologist at the National Center for Posttraumatic Stress Disorder at the VA Boston Healthcare System and assistant professor of psychiatry.
The researchers followed 233 older men who first completed an optimism questionnaire; 14 years later, they reported daily stressors along with positive and negative moods on eight consecutive evenings up to three times over an eight-year span. The researchers found more optimistic men reported not only lower negative mood but also more positive mood (beyond simply not feeling negative). They also reported having fewer stressors which was unrelated to their higher positive mood but explained their lower levels of negative mood.
While studies have increasingly supported the idea of optimism as a resource that may promote good health and longevity, we know very little about the underlying mechanisms. “Stress, on the other hand, is known to have a negative impact on our health. By looking at whether optimistic people handle day-to-day stressors differently, our findings add to knowledge about how optimism may promote good health as people age,” says Lee.
These findings appear online in the Journals of Gerontology, Series B: Psychological Sciences and Social Sciences.
