Want to stay away from colds？Put on a happy face.
Compared to unhappy people，those who are cheerful and relaxed are less likely to suffer from colds，according to a new study.It's possible that being happy helps the body fight illness，said the researchers from New York University.
“It seems that positive(积极的)feelings may reduce the danger of illness，”said the study's chief researcher Sheldon Cohen.
In an earlier study，Cohen found that people who were cheerful and lively caught coughs and colds less often.People who showed feelings were also less likely to tell their doctors that they felt ill.
In this study，Cohen's interviewed 193 adults every day for two weeks.During the interviews，the people told researchers about the happy or sad feelings they had that day.After the two weeks，the people were given colds by doctors and had to stay alone in a room for six days.
The result showed that everyone in the study was equally(相等地)likely to get ill.But for people who said they felt happy during the research period，their illness was less serious and lasted for a shorter time.
Cohen believes that when people experience positive feelings，their body may produce a chemical that helps fight illness and disease.So if you are worried about your health，look on the bright side more often.
