When Gerba tested for microbes in the bathrooms of commercial jets, he found surfaces from faucets to doorknobs to be contaminated with E. coli. It's not surprising, then, that you're 100 times more likely to catch a cold when you're airborne, according to a recent study in the Journal of Environmental Health Research. To protect yourself, try taking green tea supplements. In a 2007 study from the University of Florida, people who took a 450-milligram green tea supplement twice a day for 3 months had one-third fewer days of cold symptoms. The supplement brand used in the study was Immune Guard ($30 for 60 pills; immune-guard.us).
A doctor's office is not the place to be if you're trying to avoid germs. These tips can help limit your exposure.
1. Take your own books and magazines (and kid's toys, if you have your children or grandchildren with you).
2. Also pack your own tissues and hand sanitizers, which should be at least 60% alcohol content.
3. In the waiting room, leave at least two chairs between you and the other patients to reduce your chances of picking up their bugs. Germ droplets from coughing and sneezing can travel about 3 feet before falling to the floor.
