Happy people catch cold less quickly
If you are infected by an influenza or cold virus, the chance that you'll actually develop symptoms is forty percent less if you are happy, energetic and in harmony than if you don't have these positive feelings. A positive mood and attitude has a positive effect on your immune system, say psychologists at Carnegie Mellon University.
The 33.3 percent of the women with the least positive emotional style were more often ill than the 33.3 percent of the women with the strongest positive emotional style. A negative emotional style used to describe the subjects who were unhappy, angry or stressed did not increase the chance of developing symptoms. Apparently positive feelings improve natural resistance, but not the other way round negative feelings dont have a negative effect.
The researchers then also looked at whether the state of mind of the subjects that had become ill meant they were less affected by the infection. In this case the positive-minded subjects suffered less from the virus that had made them ill. But the subjects with negative feelings were even worse off: they were more affected by their illness than the subjects with fewer negative feelings.
"We found that the tendency to express positive emotions was associated with greater resistance to developing a cold", the researchers conclude. "We also found that positive emotional style was associated with fewer self-reported symptoms after removing the possible contributions of objective illness."
