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."
Cohen and his colleagues had found in a previous study that happier people seemed less susceptible to catching a cold,but some questions remained as to whether the emotional trait itself had the effect.
For the new study,the researchers had 193 healthy adults complete standard measures of personality traits,self-perceived health and emotional"style".Those who tended to be happy,energetic and easy-going were judged as having a positive emotional style,while those who were often unhappy,tense and hostile had a negative style.
The researchers gave them nasal drops containing either a cold virus or a particular flu virus.Over the next six days,the volunteers reported on any aches,pains,sneezing or congestion they had,while the researchers collected objective data,like daily mucus production.Cohen and his colleagues found that based on objective measures of nasal woes,happy people were less likely to develop a cold.
选项 People with a sunny disposition are immune to illness.A:Right B:Wrong C:Not mentioned
答案B
解析由文章第一段第二句的后半部分“…researchersfoundthatpeoplewithagenerallysunnydispositionwerelesslikelytofallill.”可知，性格阳光的人不太容易生病，但不是对疾病免疫。 由文章第四段，"…happierpeopleseemedlesssusceptibletocatchingacold…”可知，快乐的人更不易感冒。 由文章第六段最后一句可知，科恩和同事根据由鼻涕化验结果而得出的客观的测验数据而非主观测验发现，乐观的人患感冒的几率更小。 由文章第五段第二句可知，这些研究对象中既包括积极乐观的人，也包括悲观的人。 由文章第二段第一句可知，积极的情绪类型有助于预防感冒和其他疾病。 由文章第二段第二句可知，研究者相信快乐能够增强人的免疫系统。 文章中并未提及家庭和个人情绪类型的关系，因此本题答案为C。
