Happy people may have more immunities to common cold

22.07.2003


People who are energetic, happy and relaxed are less likely to catch colds, while those who are depressed, nervous or angry are more likely to complain about cold symptoms, whether or not they get bitten by the cold bug, according to a recent study.



Study participants who had a positive emotional style weren’t infected as often and experienced fewer symptoms compared to people with a negative emotional style, say Sheldon Cohen, Ph.D., of Carnegie Mellon University and colleagues, writing in the July issue of Psychosomatic Medicine.

Cohen’s team interviewed 334 healthy volunteers three evenings a week for two weeks to assess their emotional states. The volunteers described how they felt that day in three positive-emotion areas: vigor, well-being and calm. They were also questioned about three categories of negative feelings: depression, anxiety and hostility.


Other scientists have speculated that people who typically report experiencing negative emotions are at greater risk for disease and those who report positive emotions have less risk, says Cohen.

After their assessment, each volunteer got a squirt in the nose of a rhinovirus -- the germ that causes colds. The researchers kept the subjects under observation for five days to see whether or not they became infected and how they manifested symptoms.

"We found that experiencing positive emotions was associated with greater resistance to developing a common cold," Cohen reports. "Increases in positive emotional styles were linked with decreases in the rate of clinical colds, but a negative emotional style had no effect on whether or not people got sick."

A positive emotional style actually had no effect on how often volunteers were infected (as measured by replication of the virus) but produced fewer signs and symptoms of the illness, says Cohen. This suggests that inflammatory chemicals produced by the body may link the positive emotional style with colds.

Further analysis revealed that good health practices and lower levels of certain hormones did not account for the link between positive emotional style and illness.

Since the average person catches two to five colds a year, developing psychological risk profiles and considering ways to enhance positive emotion might reduce the risk of colds -- and by extension, other infectious diseases.

Im Focus: The “TRiC” to folding actin

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.

Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
