To prevent flu -- or any illness -- you've
got to stick with a healthy lifestyle.
"I really believe your immune system takes care of a lot of things," says
Erica Brownfield, MD, a professor of internal medicine at Emory University
School of Medicine in Atlanta. "Even if you've been exposed to the flu, you
don't have to get it."
The H1N1 swine flu virus appeared in the U.S. in April 2009 and never went away. After sweeping the globe, U.S. H1N1 swine flu cases surged as schools opened in the fall. What is H1N1 swine flu? What can we do about it? WebMD answers your questions.

The best flu prevention strategy is
basic -- good nutrition, regular exercise, and enough sleep, she tells WebMD. "You can
also wash hands frequently, and avoid people who have the flu. But really, it's
hard to prevent contact with germs. Keeping yourself healthy is generally the
best defense against the flu."
Making It Work Every Day
Eat your vegetables. A well-nourished immune system is better able
to fight off infections. It's got to be fueled with natural vitamins and
antioxidants found in healthy foods. Eat dark-green, red, and yellow vegetables
and fruits. They're packed with numerous antioxidants, plus vitamins A, C, E,
Exercise regularly. Every time you walk or run, you're boosting your
body's immunity, the natural defense against viruses. A daily 30-minute walk --
or three 10-minute walks -- is the minimum you need. Doing more provides
greater health benefits.
Get plenty of sleep. Most adults need about 7 to 8 hours sleep.
Teens need more -- about 9 hours daily. Growing kids need from 10 to 12 hours
Reduce stress. Some stress is good, but know when to relax. Too much
stress impairs the immune system.
"There are no guarantees," says Robert Schwartz, MD, chairman of family
medicine at the University of Miami School of Medicine. "You can do all these
things, lead an absolutely healthy lifestyle, and still get sick. But if you're
healthy and your immune system is working, it's possible to avoid getting the
flu. At least, you will be sick less often anyway."
