Get stressed and get a cold
There is much evidence that indicates that
the stress of every day life can influence the susceptibility to infection.
Experimental studies in which common cold viruses have been administered into
the nose of healthy volunteers have shown that there is a link between recent
history of psychological stress and susceptibility to infection. Stress appears
to be associated with the suppression of general resistance to infection that
leaves the person susceptible to infection. It is still not clear how
psychological stress affects the immune system but the most likely link appears
to be the increase in the release of corticosteroid hormones associated with
stress, as corticosteroid hormones are known to decrease resistance to
infection.
Just another reason to validate my need for a vacation. Somewhere tropical and peaceful.
