(The Record, Bergen County, NJ) -- Mom always reminded us to bundle up and don't go outside with wet hair to prevent catching a cold.
But as cold season rolls around each winter, doctors remind us that catching the common cold has nothing to do with frigid temperatures and a lot more to do with being cooped up inside in dry air.
"Being indoors is more risky, you're at more risk for exposure to people with the virus," said Dr. Steven Weisholtz, chief of infectious disease at Englewood Hospital and Medical Center.
If you do find yourself sniffling and sneezing, keep in mind there is no cure for the cold virus; antibiotics, used to treat bacterial infections, will not help. "You have to let nature take its course," said Weisholtz. Drinking lots of fluids is the best you can do, he said, and decongestants can be used to relieve nasal symptoms.
Some experts have suggested that cold season offers a chance for children to build up their immunities. Bah, humbug to the cold bug on that, responds Dr. Jeffrey S. Kahn, director of infectious diseases in the department of pediatrics at University of Texas Southwestern Medical Center.
"I would not favor exposing young infants to respiratory viruses, as this can lead to lower respiratory tract disease like pneumonia and upper respiratory tract infections, which often lead to otitis media (ear infections), which can be serious and lead to increased use of antibiotics -- not good," Kahn said. "While I agree that there may be a prevailing germ phobia in our culture and not all microbes are bad, I would not put the cold viruses in this category."
As long as children with colds don't have a fever, there's no reason they should be kept home from school, said Weisholtz. "In general each school has it owns rules. Instruct children to wash their hands regularly and teach them common courtesy to cover their nose and mouth."
The Centers for Disease Control and Prevention has been campaigning to get kids to learn to sneeze into their elbows to keep their hands clean.
That said, here's a look at common myths and how best to prevent and fight colds, according to Weisholtz, Kahn and Dr. Amber Hyde, a primary care physician; Dr. Paul Kim, a family practitioner associated with Baylor Regional Medical Center at Grapevine; and Dr. Janna Massar, an internist.
* COLDS ARE CAUSED BY COLD WEATHER.
No, they are caused by viruses. However, you might be more susceptible to colds in the winter months because you tend to go indoors in crowded environments where you are more likely to pick up other people's viruses. Plus, there are some strains of cold viruses that thrive in the cold, and cold weather can dry out your sinuses, making them more vulnerable to infection.
* YOU CAN CATCH A COLD BY GOING OUTSIDE WITH WET HAIR OR DAMP CLOTHES.
No, but being wet can weaken your immune system, which makes it more likely that you can catch a cold.
* IT'S EASY TO SPOT A COLD.
No, it can be challenging to diagnose because there's a lot of overlap among upper respiratory infections. Untreated allergies can lead to colds, and colds can be a breeding ground for bacterial infections. You can help your doctor distinguish between an allergy and cold by telling him or her if you get your symptoms consistently at specific times of year when certain allergens might be in play.
* THE BEST CURE IS VITAMIN C.
No, there's no proof that vitamin C helps, but vitamins C and B- 12 have fans among medical professionals, and they can't hurt.
Some experts strongly recommend zinc lozenges, but because of divergent studies, the National Institutes of Health only asserts "zinc lozenges might be useful as a treatment option." It recommends more research and caution, particularly after the U.S. Food and Drug Administration warned consumers to stop using three Zicam intranasal cold-remedy products containing zinc when some users lost their sense of smell.
In contrast, studies show that good old chicken soup, which seems to have anti-inflammatory properties, might reduce the length and severity of colds. Drinking lots of fluids, gargling with salt water and breathing warm, humidified air that moistens your sinuses can help, too, by easing congestion.
* YOU'RE LESS LIKELY TO GET SICK IF YOU WASH YOUR HANDS AND USE HAND SANITIZERS.
Yes, hand sanitizers can reduce your chances of getting sick by killing the viruses that cause the common cold. Washing hands frequently with soap and water for 30 seconds at a time is recommended. Kissing and hugging people who have colds is not recommended.
* THE FLU IS JUST A BIG COLD -- WAIT IT OUT.
No, the flu is a virus, as the cold is, but you should seek treatment right away, as the flu has the potential to be life- threatening. Deaths in a three-decade period ranged from 3,000 to as high as 49,000 per season, while an average of 200,000 people a year are hospitalized, according to the Centers for Disease Control and Prevention.
You know you're dealing with the flu, rather than a cold, if your temperature is 103 degrees or greater and you have a sudden onset of high fever, body aches and pains in six hours or less, which is not the case for colds.
Better yet, don't wait to get the flu, say the experts at the CDC's National Center for Immunization and Respiratory Diseases. If you haven't been vaccinated yet, they advise getting immunized now - - particularly children, senior citizens, pregnant women or those with chronic medical conditions such as asthma, diabetes and heart disease, as these factors put you at high risk for serious flu- related complications.
The vaccine usually takes one to two weeks to give protective immunity, but the flu season typically lasts six to eight weeks or longer.
