Everyday mistakes can raise your risk of catching a cold—and that includes touching surfaces that many, many other people have touched. A University of Arizona study found that a virus spreads to over 50 percent of surfaces and other employees within hours when a single person in an office is infected. Partha Nandi, MD, a leading physician and author of Ask Dr. Nandi, advises avoiding touching common surfaces when possible. Even after you wash your hands, “use a paper towel to turn off the faucet,” he says. These are the nine signs a cold is coming–and how you can stop it.
They drink enough water
Great things happen to your body when you get enough water, one of which is flushing out germs that could make you sick. “Stay hydrated,” advises Renee Miranda, MD, a family medicine physician at The Ohio State University Wexner Medical Center. How do you know how much to drink? “Take your weight in pounds, divide in half, and this is approximately how many ounces of water you need a day,” she says. “For example, someone who is 150 pounds needs about 75 ounces of water a day.” This is what happens when you get your full 8 glasses of water.
