Mothers are celebrated (if sometimes vilified) for their eagerness to advise
their children on matters big and small: how to behave, what to wear, whom to
marry, when to have kids ... and, oh yes, how to stay healthy during cold and
Does science back up what Dr. Mom told you about the common cold? Or was she
full of hot air? Here's what real doctors have to say about 10 familiar
Why do half of Americans fear the H1N1 swine flu vaccine more
than pandemic flu itself?
It's a problem that bedevils the huge effort now underway to offer the
vaccine to all Americans who want it.
"People have concerns about vaccination ... despite the clear message from
all of us in public health and doctors throughout the health care field that
vaccine is our best tool to protect against the flu," CDC director Thomas
Frieden, MD, said at a news conference aimed at convincing U.S. residents...
Mom was right on this one. Colds commonly spread when we touch someone or
something that harbors cold-causing viruses and then infect ourselves by
touching our nose or eyes. Hand washing is great at eliminating these viruses
before they sicken us (and before we spread them to others).
Hand sanitizers work well, as does plain old soap and water (no need for
antibacterial soap). The key is to wash thoroughly -- and regularly.
"Hand washing is part of the routine in my home," says William Schaffner,
MD, chairman of the department of preventive medicine at Vanderbilt Medical
School in Nashville, Tenn. "The first thing we do after coming home is hang up
our jackets, and then we wash our hands."
Be aware that cold viruses can survive on objects for several hours --
perhaps overnight, says infectious disease specialist J. Owen Hendley, MD,
professor of pediatrics at the University of Virginia Health System in
2. "Have a little chicken soup, dear."
Seems mother may have been on to something with this one, too. Limited
research suggests that it can be helpful. A University of Nebraska study shows
that traditional chicken soup "may contain a number of substances with
beneficial medicinal activity."
What's more, the hot vapors rising from a bowl of broth help open a stuffy
nose, and consuming liquid of any kind helps keep you hydrated.
Anything else? Chicken soup may melt your malaise simply by reminding you of
the love of a devoted parent. "If chicken soup makes you feel better, use it,"
3. "Feed a cold, starve a fever."
Scant research has been done on this familiar advice. A small study
published in 2002 suggests that eating may influence short-term immune
function, but whether this has any effect on the course of a cold is
Hendley, for one, is unconvinced. "This is a faintly titillating study," he
says. "But it provides no support for the 'feed a cold' idea. I grew up hearing
this advice, but I just don't believe it's true."
Schaffner recommends "listening to your body": If you feel hungry, he says
eat something simple, like soup, applesauce, or toast.
4. "Bundle up, or you'll catch your death of cold."
Mom was way off base here. There's no evidence that low temperatures or damp
conditions make you more vulnerable to colds.
Colds are more common in colder seasons, but scientists now believe this is
due in part because low temperatures and low humidity facilitate the
transmission of virus-laden microscopic moisture droplets from person to
person, says Schaffner. So while a warm coat and galoshes may make you comfy in
inclement weather, they won't protect you from colds.
