This year's cold and flu season will feel like one of the latest Batman or Spider-Man flicks: You won't just be battling one villain; you'll have to fight off several. Experts predict two flu epidemics: the regular seasonal flu and the possibly pandemic-causing swine flu (along with the usual plethora of rhinoviruses, of course). Colds and flu bugs spread from person to person, so unless you're a cave-dwelling hermit, you're at risk.
What to do? Boost your immune system now to dodge these viral bullets.
1. Get Shot
To keep performing at your best, you'll need to roll up your sleeve. According to the Centers for Disease Control and Prevention (CDC), the most powerful tool for preventing flu -- both seasonal and swine -- is the annual flu shot, available in October and November from doctors, public health departments and some pharmacies (Walgreens, for example). Flu shots rev up the immune system to prevent flu infection. This year you'll need one shot to prevent seasonal flu and another to prevent swine flu. (The swine flu vaccine is currently in the final stages of testing.)
2. Become a Friend of Herbs
Another way to enhance immune function is to take immune-boosting herbs. A great deal of research shows that some herbs activate the immune system against colds, flu and other diseases. For example:
Canadian researchers gave 279 adults, ages 18 to 65, either a placebo or dose of ginseng (200 mg twice a day). Four months later, the ginseng group suffered fewer than half as many colds -- and the ones they did develop were brief and mild. Likewise, University of Connecticut researchers gave flu shots to 43 people over 65 years, plus a placebo or ginseng (200 mg twice a day). The ginseng group was 50 percent less likely to develop flu. Finally, at Eastern Virginia Medical School, researchers gave flu shots to 198 nursing home residents, plus either a placebo or ginseng (200 mg twice a day). After three months, the ginseng group was an astonishing 89 percent less likely to catch flu.
Ginseng is available at health food stores and supplement shops. Take 200 mg twice a day or follow package directions.
3, 4 and 5. Just Plain Live Healthy
And let's not forget standard health advice, which keeps the immune system in top form:
6. Picture Your Health
Finally, as you get your flu shots, take immune-boosting herbs, get more sleep, eat salads and exercise, visualize your immune system growing stronger and devouring cold and flu viruses. Visualization, also known as guided imagery or self-hypnosis, is a form a meditation, and many studies show that meditation boosts immune function. In a 2003 study, University of Wisconsin researchers gave flu shots to 41 young adults, 25 of whom had been taught visualization-based meditation. The visualization group showed a stronger immune response to the vaccine, meaning greater protection from flu.
