Hand - Washing, zinc best weapons against common cold?

It's something we all try to avoid: catching a cold. And even though there's no known cure for it, researchers at the University of Alberta in Canada think they've found the best way to stay healthy. "You know what they found?" "What?" "If you wash your hands, it is an extremely effective way to stay healthy." "How much did they pay for this thing?" (Via WFLX) Yes, after reviewing 67 randomized controlled trials, researchers determined hand-washing is the most effective way to prevent a cold, Red Orbit reports. That and taking zinc supplements. Study leader Dr. Michael Allan says not to take zinc on a regular basis, though, because it can cause nausea. One WLNY anchor has a tip to help with that.

So I like to take it with some food, you know, if you're going to do the zinc." (Via WLNY) The study also mentioned probiotics showed signs of preventing colds, but vitamin C, not so much. If you've already caught a cold, researchers suggest acetaminophen, ibuprofen and decongestants help with congestion, sore throats and fevers.

Combining those with decongestants and pain relievers is more effective for those older than 5. The study was published in the Canadian Medical Association Journal.
