Studies of the impact of mood on physical health need to account for both positive and negative emotions, Cohen holds. He points to preliminary data from other teams suggesting that among depressed people, a lack of positive emotions is a more accurate predictor of stroke than is the extent of their negative emotions.
-
In that project, Cohen's team interviewed 193 healthy adults by phone each evening for 2 weeks. The participants reported their positive and negative emotions during that day. They then received nasal drops containing a rhinovirus or an influenza virus that causes a coldlike illness.
Each person was quarantined in a separate room and monitored for 5 or 6 days. Although a positive emotional style bore no relation to whether participants became infected, it protected against the emergence of cold symptoms. For instance, among people infected by the influenza virus, 14 of 50 (28 percent) who often reported positive emotions developed coughs, congestion, and other cold symptoms, as compared with 23 of 56 infected individuals (41 percent) who rarely reported positive emotions.
-
psychological traits related to a positive emotional style, rather than the emotions themselves, guard against cold symptoms. Those traits include high self-esteem, extroversion, optimism, and a feeling of mastery over one's life.
-
People with generally positive outlooks show greater resistance to developing colds than do individuals who rarely revel in upbeat feelings, a new investigation finds.
