     Compared to people with bad attitudes , people who are cheerful and relaxed are less

likely to suffer from colds, according to a new study. " It'spossiblethatbeingupbeathelpsthe

bodyfight illnesses", says Sheldon Cohen, the study's lead researcher from Camegie Mellon

University( CMU) in Pittsburgh.

     In a previous study,Cohen and his colleagues put cold-causing viruses into the noses

of 334 healthy adults. People who tended to be cheerful and lively were least likely to

develop sniffles, coughs , and other cold symptoms. People who showed positive feelings

were also less likely to mention symptoms to their doctors , even whenmedical tests

detected those symptoms.

     Those findings were interesting, but they didn't prove that a person's attitude affects

whether he or she gets sick. Instead,it was still possible that a person's underlying

personality is what matters.Evidence suggests, for instance, that certain people are

naturally more likely to be outgoing and optimistic , with high self-esteem and a sense

of control over life. This would mean that who we are, not how we feel, ultimately

decides our chances of catching colds.

     To figure out which mattered more ( personality or emotions) , the CMU team

interviewed 193 healthy adults. The researchers talked to each person over the phone

every evening for 2 weeks. At the end of the interviewing period, people got nose drops

that contained either cold or flu viruses. Then, each person stayed in an isolated room

for 5 0r 6 days. The results showed that everyone in the study was equally likely to get

infected. Their symptoms, however, differed depending on the types of emotions that

they had reported over the previous 2 weeks. Among those who reported good moods

and had been infected with the flu virus, for example,28 percent developed coughs and

stuffy noses. On the other hand, those symptoms struck 41 percent of people who had

been less upbeat.
