     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's possible that being upbeat helps the body fight illnesses,  "

says Sheldon Cohen,  the study's lead researcher from Carnegie Mellon University (CMU) in Pittsburgh.

     In a previous study,  Cohen and his colleagues put coldcausing 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 when medical 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 selfesteem 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 or 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.
