Preventing and Treating a Cold: What Works? | LiveScience

Washing hands and taking zinc may be the best ways to avoid getting the common cold, and over-the-counter pain relievers are the recommended treatments to alleviate the symptoms, according to a new review.

The common cold strikes adults two to three times a year on average, while children under age 2 develop colds about six times a year, according to the study. There\'s no vaccine or cure for the cold, which usually takes only a few days to resolve on its own but can be bothersome and debilitating.

To identify the best ways to prevent getting a cold, or help alleviate its symptoms once it has struck, researchers reviewed more than 150 studies of both traditional and nontraditional approaches, ranging from gargling water to eating garlic.
