Why the Flu is Most Prevalent in Winter

A new study by the National Institutes of Health (NIH) finally explains why the flu virus is more infectious in winter:

At winter temperatures, the virus's outer covering, or envelope, hardens to a rubbery gel that shields the virus as it passes from person to person. With warmer weather, however, the protective gel melts to a liquid phase. But this liquid phase, apparently, isn't tough enough to protect the virus against the elements, and so the virus loses its ability to spread from person to person.

Dr. Joshua Zimmerberg, the senior author of the study, explains in layman's terms how the virus is able to infect our bodies: "Like an M&M in your mouth, the protective covering melts when it enters the respiratory tract. It's only in this liquid phase that the virus is capable of entering a cell to infect it."

So, what can you do to prevent the flu? One option is to live somewhere warm, like Florida. Otherwise, you can work to boost your immune system. Take a look at some tips offered by WebMD, Natural News, and Dr. Gwenn.

I have personally seen the high costs and inner workings of the health care system. My best friend was in a coma for 12 days and had brain surgery. My mom battled leukemia for 10 months and passed away in February of 2007. I know firsthand that our health care system is in dire need of change and am personally dedicated to working to bring about that change.
