At one time or another, every one of us succumbs to the common cold. The bravest, the strongest, the sweetest, the smartest—our virtues matter not to these viruses as they set about reducing us to coughing, sneezing shadows of our former selves.
Worse yet, there's no cure. Antibiotics, champs at knocking out bacterial infections, are down for the count against cold viruses. So we sniffle on bravely, maybe take a cold pill or two, and hope the symptoms will disappear in the customary week or so.
But there's actually a lot more we can do to get through a cold more comfortably, say doctors who specialize in self-care medicine. Some remedies, they say, may even help us overcome a cold more quickly. Here are the best remedies the experts have to offer.
Take C and see. "Vitamin C works in the body as a scavenger, picking up all sorts of trash—including virus trash," says Keith W. Sehnert, M.D., a physician with Trinity Health Care in Minneapolis, Minnesota. "It can shorten the length of a cold from seven days to maybe two or three days."

Vitamin C may also cut back on coughing, sneezing, and other symptoms. In a study conducted at the University of Wisconsin, cold sufferers taking 500 milligrams of vitamin C four times per day suffered about half as many symptoms as those not taking the vitamin.
Short-term use of such high doses shouldn't cause any side effects, says Dr. Sehnert. But you should get your doctor's okay before starting any supplement program. Better yet, simply get your additional vitamin C by drinking it. Orange, grapefruit, and cranberry juices are rich sources of vitamin C.
Zap it with zinc. Sucking on zinc lozenges can cut colds short, to an average of four days, researchers in Great Britain and the United States have discovered. Zinc can also dramatically reduce symptoms such as a dry, irritated throat, says Elson Haas, M.D., director of the Marin Clinic of Preventive Medicine and Health Education in San Rafael, California. "It doesn't work for everyone, but when it works, it works," he says.
The down side is that zinc has an unpleasant taste. There are, however, lozenges on the market that contain honey and/or citrus that are a lot easier to swallow. But do not take more than the amount recommended by your doctor. Zinc can be toxic in large doses.

Be positive. A positive attitude about your body's ability to heal itself can actually mobilize immune system forces, says Martin Rossman, M.D., a general practitioner in Mill Valley, California. He teaches this theory by getting his patients to practice imagery techniqeus to combat colds. After bringing yourself into a deeply relaxed state, "imagine a white tornado decongesting your stuffed-up sinuses," he suggests, "or an army of microscopic maids cleaning up germs with buckets of disinfectant."
Rest and relax. Extra rest enables you to put all your energy into getting well. It can also help you avoid complications like bronchitis and pneumonia, says Samuel Caughron, M.D., a family practitioner specializing in preventive medicine in Charlottesville, Virginia.
Take a day or two off from work if you're feeling really bad, he advises. At the very least, slow down in your everyday activities and reschedule your time. "Trying to keep up with your regular routine can be draining because when you're not feeling well, your concentration is down and you'll probably need to double the amount of time it's going to take you to do things," he says.
Turn out the party lights. When you're sick, parties and other good times can wear you out physically, compromising your immune system and causing your cold to linger, says Timothy Van Ert, M.D., a physician in San Francisco and Saratoga, California, specializing in self-care and preventive medicine. Let the good times roll right on by until you feel better.
Warm up. Keep bundled up against the cold, advises Dr. Sehnert. This keep your immune system cozily focused on fighting your cold infection instead of displacing energy to protect you from the cold.
Take a walk. Mild exercise improves your circulation, helping your immune system circulate infection-fighting antibodies, says Dr. Sehnert. "Jump on a gentle rebounder indoors for 15 minutes or take a brisk half-hour walk," he suggests. But refrain from strenuous exercise, he warns, which could wear you out.
Feed a cold—lightly. The very fact that you have a cold in the first place may point to your eating "too congesting a diet" that puts a strain on your body's metabolism, says Dr. Haas. Counteract it, he advises, by eating fewer fatty foods, meat and milk products, and more fresh fruit and vegetables.
Sip chicken soup. A long-time folk remedy is now a proven fact. A cup of hot chicken soup can help unclog your nasal passages. Researchers at Mount Sinai Medical Center in Miami Beach found that hot chicken soup, either because of its aroma or its taste, "appears to possess an additional substance for increasing the flow of nasal mucus." These secretions—what comes out when you blow your nose or sneeze—serve a first line of defense in removing germs from your system, the researchers say.
Load up on liquids. Drink six to eight glasses of water, juice, tea, and other mostly clear liquids daily, advises Dr. Sehnert. This will replace important fluids lost during a cold and help flush out impurities that may be preying on your system.
Butt out. Smoking aggravates a throat that may already feel irritated from a cold, says Dr. Caughron. It also interferes with the infection-fighting activity of cilia, the microscopic "fingers" that sweep bacteria out of your lungs and throat. So if you can't kick the habit for good, at least do it while you've got a cold.
Soothe with saltwater. Relieve an irritated throat by gargling morning, noon, and night—or whenever it hurts most, Dr. Van Ert advises. Fill a glass with warm water and mix in 1 teaspoon of salt.
Sip a hot toddy. Clear your stuffed-up nose and help yourself to a good night's sleep by drinking a "hot toddy" or half a glass of wine before bedtime, suggests Dr. Caughron. But more alcohol than that can stress your system, he says, making recovery from illness more difficult.
Get yourself in hot water. Taking a steamy shower can help clear congestion, says Kenneth Peters, M.D., an internist specializing in self-care and chronic pain in Mountain View, California. Or heat a teakettle or pot of water to boiling on your stove, turn off the flame, drape a towel in a tent over your head and the kettle, and inhale the steam until it subsides. This also relieves your cough by moistening your dry throat, he says.
Go for the grease. Relieve a nose raw from blowing by applying a lubricating layer of petroleum jelly around and slightly inside your nostrils with a cotton swab, suggests Dr. Peters.
Medicate at night. Numerous medications for colds are available without a prescription. Some treat specific symptoms. Others, like Nyquil and Contac, contain a combination of drugs—plus alcohol, in some cases—aimed at treating a wide range of symptoms. These combination drugs, however, can have many uncomfortable side effects like nausea and drowsiness, says Dr. Van Ert. "I recommend that these be taken only at night, since you won't feel the side effects while you're sleeping."
He says that if you need to take medications during the day, take only those that treat the symptoms you're suffering from. Be sure to follow the instructions carefully, he advises, and give children only a child-size dose. Here's what to reach for.

Don't spread your germs. When you need to cough, go ahead and cough. When you need to blow your nose, go ahead and blow. But cough and sneeze into disposable tissues instead of setting germs free in the environment, Dr. Van Ert advises, then promptly throw the tissue away and wash your hands. Your healthy friends and family who want to stay that way will appreciate it.
