乐观者对感冒的抵抗力更强?

 【英文原文】

You’ve probably heard it said that one’s attitude affects one’s health.Over three-hundred subjects were assessed in terms of their emotions for a two- week period. They were assessed for positive emotions they might be feeling, such as vigor¹, well-being², and calmness, as well as for negative emotions such as depression, anxiety, and hostility³. Then they were each given a squirt in the nose of the virus that causes common colds. The interesting thing is that emotional states had no effect on whether or not subjects were technically⁴ infected with the virus, which is measured by evidence of replication of the virus in the subject’s body.

Emotional states did, however, affect the symptoms the virus manifested. People with more positive emotional states were less likely to suffer or complain about symptoms of the cold than people with negative emotional states. In addition, the relative health practices of positive vs. negative people did not account for this result. So there really does seem to be a link between emotional state and illness.
