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 character were less likely to fall ill.
The findings, published in the journal Psychosomatic Medicine, build on evidence that a “positive feeling style” can help get rid of the common cold and other illnesses. Researchers believe the reasons may be both objective（客观的） as in happiness improving immune function and subjective as in happy people being less troubled by a throat ache or runny nose.
“People with a positive feeling style may have different immune responses to the virus,” explained Dr Sheldon Cohen. “And when they do get a cold, they may stop their illness from being more severe.”
Cohen found in a previous study that happier people seemed less easy to catch a cold. However, some questions remained as to whether the feeling itself had the effect.
For the new study, the researchers ask 193 healthy adults to complete some standard measures of personality and feeling style. Those who tended to be happy, energetic and easy-going were judged as having a positive feeling style, while those who were often unhappy, tense and depressed had a negative style.
The researchers gave them some drops containing either a cold virus or a particular flu virus. Over the next six days, the volunteers reported on any aches, pains, sneezing they had. While the researchers collected objective data like daily mucus（粘液）production, Cohen and his partners found that warm people were likely to keep cold at bay.
