    Test Your Cough IQ

    Do you hear that coughing sound? It's cold and flu season, and people all around you are coughing. Why? "Coughing is a normal, protective reflex," says Neil Schachter, MD, author of The Good Doctor's Guide to Colds and Flu. "We cough to clear our airways," he explains. Think of coughing as a defense mechanism designed to rid your lungs and windpipe of substances that don't belong there. In the case of colds, this intruder is usually mucus, which builds up more than the airways can comfortably...

    No. 1: Wash Your Hands

    There's no mystery about how cold and flu viruses spread. Someone who's sick sneezes in his hand and then touches the telephone, the keyboard, or a kitchen glass. You can pick up the germ when you touch that object, even hours later.

    So wash your hands often. If you can't get to a sink, rub them with a hand sanitizer that's got alcohol in it.

    No. 2: Don't Cover Your Sneezes and Coughs With Your Hands

    Do your part to keep germs away from your family and friends. Viruses cling to your bare hands, so don't use them to muffle your coughs and sneezes.

    When you feel one coming, use a tissue, then throw it away. If you don't have one with you, cough or sneeze into the inside of your elbow.

    No. 3: Don't Touch Your Face

    Cold and flu viruses enter your body through your eyes, nose, and mouth. Teach your kids not to touch their faces -- and follow your own advice.

    No. 4: Do Aerobic Exercise Regularly

    Aerobic exercise is any activity that gets your heart pumping. It helps increase your body's natural virus-killing cells.

    No. 5: Eat Foods Containing Phytochemicals

    "Phyto" means plants, and the natural chemicals in them give the vitamins in food a supercharged boost. So put away the vitamin pill and eat dark green, red, and yellow veggies and fruits.

    No. 6: Don't Smoke

    Heavy smokers get more severe and frequent colds. Even being around smoke hurts the immune system, your body's defense against germs.

    Smoke dries out the passages in your nose. It affects your cilia -- the delicate hairs that line your nose and lungs and help sweep away cold and flu viruses. Experts say just one cigarette can stop them from working for as long as 30 to 40 minutes.
