14 Ways to Avoid Colds and Flu

Sanitize yourself
Keep sanitizing gel or alcohol-based hand wipes on you at all times. But read the label before you buy, says Robertson: Some wipes are not alcohol-based and wont be as effective.

Another reason to quit
Smoking increases the risk of infections by making structural changes in the respiratory tract and decreasing immune response, according to a study of smokers and infection published in the Archives of Internal Medicine in 2004. In particular, Mengel says, smoking destroys cilia, the little hairlike fibers inside our noses; this can help increase infection risks.

Did you just double dip that chip?
Beware of the dip. It may be harboring more than savory salsa. Double-dippers may be passing germs to those who eat after them, Mengel says.

Another reason to shop
Our purses pick up germs like we do, according to Joseph Brasco, MD, author of The Great Physicians Rx for Colds and Flu, so you could be re-infecting yourself every time you pick up your handbag. His suggestion: Put away your cloth purse during the winter months and carry one made of easier-to-wipe-down vinyl or leather. Of course, you could always just buy more purses.

I hear your mother calling
Biting your nails may be hurting you, Brasco says. Germs get under your nails and nibbling is a fast way to ingest them.

Try to smile
New research has found that happiness may help you. Carl Charnetski, MD, professor of psychology at Wilkes University, found that sex, positive thinking, playing with a pet, and other pleasurable behaviors will boost your immune system.

You want me to sneeze where?
It may sound strange, but when you have to cough and sneeze, do so into the crook of your elbow, not into your hands. Since your hands are a common source of germs, doing that will prevent them from spreading, Kulze says.

Already sick?
Here are four things you can do to get better, according to Jeff Robertson, MD, and chief medical officer for health insurer Regence.

Take some alone time
This is the when youll want to shy away from company. Stay home and take care of yourself.

Watch your symptoms
If it goes from simple sniffles to raging sickness, contact your doctor. Your cold may have escalated to the flu.

Drink, drink, drink
Dehydration can easily occur (especially if you are running a fever or vomiting). If youre unable to keep fluids down, contact your physician.

Nows not the time to save up
Dispose of all used tissues. As easy as it is to grab whatever is on the nightstand (including crumpled Kleenex), dont! You may be furthering the cold.
