Staying positive through the cold season could be your best defense against getting ill, new study findings suggest. In an experiment that exposed healthy volunteers to a cold or flu virus, researchers found that people with a generally sunny disposition were less likely to fall ill. The findings, published in the journal Psychosomatic Medicine, build on evidence that a "positive emotional style" can help ward off the common cold and other illnesses. Researchers believe the reasons may be both objective as in happiness boosting immune function and subjective as in happy people being less troubled by a scratchy throat or runny nose. "People with a positive emotional style may have different immune responses to the virus," explained lead study author Dr. Sheldon Cohen of Carnegie Mellon University in Pittsburgh. "And when they do get a cold, they may interpret their illness as being less severe."
最新研究表明，保持快乐的心情是预防寒冷季节生病的最佳方法。 在一项实验中，研究人员让一群身体健康的志愿者去接触感冒病毒或流感病毒，结果发现，性格开朗的人患病的几率较小。这项研究结果发表在《身心医学》期刊上，其主要依据是“积极的情绪”有助于预防感冒和其他疾病。 研究人员认为，这可以从客观和主观两方面来解释。从客观上说，快乐的情绪可以增强人体的免疫力；从主观上说，快乐的人对于嗓子疼、流鼻涕等感冒症状没那么敏感。研究报告的主要撰写人、匹兹堡卡内基·梅隆大学的谢尔登·科恩博士解释说：“‘情绪积极’的人对于病毒的免疫力较强，而且，即使患了感冒，他们也觉得没什么大不了的。”
