Being an optimistic person might help you improve your emotional well-being. In a new study published in the Journals of Gerontology, researchers at Boston University compiled data from 233 older men from the Veterans Affairs Normative Aging Study over eight years. They found that those who were more optimistic reported lower negative moods and more positive moods, as well as fewer life stressors. The optimism appeared to enhance emotional well-being by limiting how often the men experienced stressful situations or changing the way they interpreted situations as stressful. In other words, more optimistic people handle daily stress more constructively.
