On Saturdays during the winter when I was five or six
years old I was taken to the doctor for cold shots. Sixty years later, a cure for the common cold
remains as elusive as ever and I am wondering what was in those shots. These days I don’t get many colds, which is
typical for the over-fifty crowd. The
rhinoviruses that cause colds, though many, are limited in number. After fifty years of two or more colds per
year my body has developed immunity to lots of them.
For the most part, I have acquired my cold resistance the
hard way, one cold at a time, but I’ve also learned some helpful
strategies. When we had colds as
children, my brothers and I were sent to school, business as usual, unless we
had a fever. These days, when I first
get a sore throat, I immediately try to slow down in order to let my immune
system do its work. I prepare meals and
do some regular activities, including a little exercise, but no strenuous workouts. The most important parts of my strategy are
to take zinc lozenges (Cold-Eeze) and to sleep extra hours, probably a long nap
in the afternoon in addition to 7-8 hours at night. If I can do this, very often the threatened
cold goes away without any further symptoms.
When I was younger, colds used to last for a miserable
week or ten days of sore throat, sneezing, and coughing, often succeeded by
lingering chest congestion. Sometimes all
that would be followed by secondary infections that could drag on for
weeks. These days, once in a great while,
I get a cold that really knocks me sideways – but it never lasts more than a
couple of days. This happened to me last
week. On Wednesday I got a sore throat
and started taking zinc lozenges and resting.
By Thursday I was sneezing but I felt OK. Friday I was totally wiped out – my sinuses
hurt, my teeth all ached in unison, my throat was raw – and I spent most of the
day sleeping. When I woke up Saturday
morning, it had pretty much all gone by, though I felt a little as if I had
been in a fight, and today (Sunday) it
is hard to believe that it even happened.
Why do I get shorter, nastier colds? Apparently, it’s
because my immune system now is stronger than it was when I was younger. As Jennifer Ackerman points out, cold
symptoms are caused not by the virus but by the action of the immune system in
fighting it off. The more powerful the
response, the worse you feel. The
trade-off, I believe, is that the cold gets knocked out of your system much
faster so that you spend more days feeling good and have a reduced risk of secondary
infections.
Medical science has learned a lot about colds in recent
years. It seems that genetic variations
may cause some people to get more colds than others. Also, the more
years your parents owned their own home before you were 18, the less likely you are to get a lot of
colds during your lifetime. The key here
is stress, which can reduce the ability of the immune system to regulate
inflammation, leaving the body more vulnerable to disease. Important research in this area has been done
by Sheldon Cohen at Carnegie Mellon University.
Coldwise, my destiny may have been forged in early childhood. My parents never owned their own home – we
lived in a place provided by the church where my father was rector – and there
was always plenty of stress. As for the
cure for the common cold, we’re still waiting.
