How to Dodge the Flu Without a Shot

Even without a flu shot, you can still do something to protect yourself.

Preventing the Flu Without Shots continued...

Other recommendations include getting plenty of rest, eating a healthy diet, drinking plenty of fluids, and getting plenty of exercise.

According to the American Council on Exercise, research has shown that moderate exercise (such as brisk walking) brings about measurable changes in the immune system, sending white blood cells zipping around the body to find intruders and kill them. But after a few hours, the immune system returns to normal so it's best to exercise regularly.

Rita Beckford, MD, a spokeswoman for the American Council on Exercise, also cites studies that show that those who exercise four to five times a week are less likely to get colds or other viruses.

What to Do With the Flu

Most healthy people will recover from the flu in seven to 10 days and luckily, the worst symptoms go away within four days. Most drugstore regimens aim to lessen these symptoms.

If that's not enough for you, consider an antiviral medicine. Most people are unaware of four antiviral medicines (Amantadine, rimantadine, Relenza, and Tamiflu) available from your doctor, which can cut the severity of flu and shorten the duration of symptoms. But these only work if you start them within two days of contracting the flu virus.

In addition, web sites and drug stores are filled with herbals, vitamins, supplements, and other remedies that claim to treat the flu or improve symptoms.

The hottest remedy this year is called oscillococcinum (os-sill-oh-cox-sin-um). This is a homeopathic remedy, in which vanishingly small amounts of a disease cause are given to make the body turn against the cause. Sometimes such preparations are so diluted not a single molecule remains. Recently, it was at the top of's list of top sellers.

Some swear by homeopathic remedies, but others scorn them. Both Stamm and Snow do not recommend this approach. "Speaking personally and not for the American College of Physicians," Snow says, "I think that if the government does not regulate a substance, you don't know what it contains." Proceed at your own risk with these. Stamm and Snow also did not endorse echinacea, Zicam, or taking increased doses of vitamin C.

Once you get the flu, most experts recommend bed rest, plenty of fluids, over-the counter fever reducers and ache alleviators, a light diet, and good old chicken soup!

Fitness instructor Beckford also recommends that you not exercise until you are well.
