How to Stop a Cold (or the Flu) Before it Starts

-

What works -- and what doesn't -- when it comes to revving up your immune system

Once you notice trees dropping their leaves, days getting shorter, nights getting darker, and the air feeling a little crisper, you can be sure of two things: Drugstore aisles will be crammed with cold and flu preventions, from echinacea to zinc. And "coffee talk" with friends, family, and coworkers will inevitably turn to how to prevent a cold or the flu – or even ways to steer clear of the latest virus.
Seems like everyone has his or her own method for preventing colds and flu, from simple rules like never leaving the house with wet hair, to more deliberate methods such as:
  • Taking a special combo of vitamins and minerals
  • Sipping an effervescent vitamin drink
  • Getting a daily dose of an herbal remedy
  • Loading up on garlic
You know that taking steps to protect your immune system is wise. In fact, doing so can make your RealAge as much as 6 years younger. But on the flip side, taking unnecessary vitamins and supplements can make your RealAge almost 2 years older.
So with cold and flu season right around the corner, it's important to know which, if any, supplements can really help prevent a cold or the flu. Take our quick interactive quiz and find out how to stop a cold in its tracks.

What really keeps cold and flu bugs at bay?

1. Your neighbor is an avid skier and swears that taking vitamin C every day keeps her healthy and on the slopes. She also claims it will help keep you cold-free. Is she right?
  • Yes
  • No
  • Maybe

The correct answer is:

Maybe
It depends on how active you are. Despite long-held beliefs linking vitamin C and cold prevention, the only people for whom a daily dose of vitamin C has proved to reduce the incidence of colds are those who regularly engage in strenuous outdoor activities in cold climates.
2. You saw a woman at the health food store stocking up on echinacea and overheard her tell her friend that it's a cold's worst enemy. Is it?
  • Yes
  • No
  • Maybe

The correct answer is:

Yes and No
This herbal remedy has not proved effective at preventing colds, but it may be helpful in treating them.
3. You clipped a coupon from the local paper for a new probiotic supplement. Could this be the answer to preventing colds and the flu?
  • Yes
  • No
  • Maybe

The correct answer is:

No
Probiotics are the latest buzz in the nutrition world, and although the latest studies show they may help to shorten the duration of a cold, they don't seem to prevent them.

Best Way to Stay Healthy? Call In Sick

-
Next time you get a sore throat and sniffles, here's what you need to do to avoid can't-get-out-of-bed misery later: stay home. Research shows that people who report to work sick are much more likely to get laid out flat by an even nastier bout of illness down the road. Sick at Work People who came to work sick at least six times within the previous year were 50 percent more likely to need extended sick leave later on -- as much as two or more weeks off within the next 18 months. Why is punching the clock when you're sick so bad? Researchers speculate that when people don't take time to rest and recuperate, the body gets more and more run down -- to the point where it can't keep a little illness from ballooning into big trouble.    Healthy Solution Okay, so sometimes you might feel like you really just don't have time to be sick. Or maybe you don't have the luxury of copious sick days. If you can swing it, stay home. But also try these

6 Reasons to Get a Flu Shot This Year

-
Did you decide to skip your flu shot this year? If so, you might want to rethink that. Here's why: Getting the shot is the single best way for nearly everyone to prevent the flu, according to the U.S. Centers for Disease Control and Prevention (CDC). So, what's stopping you? Here are 6 common excuses, and why you should reconsider: It's too late. It's true, getting a flu shot early in the season offers the best protection, but the shot is effective anytime, even if you wait until December. Flu activity typically peaks in January or February and can last as late as May. I'm healthy. The flu vaccine is especially important for high-risk people (pregnant women, young kids, older folks, and anyone with a compromised immune system), but the rest of us need it, too. Having the shot will prevent you from wasting precious vacation days or (worse!) going to work sick and sharing the virus with your coworkers. I had a flu shot last year. Smart move! Get ano
