Is it “Feed a cold and starve a fever,” or “Starve a cold and feed a fever?” Every parent has heard that so-called medical advice, probably from their parents and grandparents. But Dr. Stephen Lauer, a pediatrician at The University of Kansas Hospital, says neither is true. In this video, he addresses four of the top medical “myths” he hears most often in his clinic, and gives the actual medical facts.

• Myth #1 Starve a fever, feed a cold
• Myth #2 Green or yellow mucus means you have a sinus infection; clear is just a cold
• Myth #3 You lose 75% of your body heat through your head
• Myth #4 Colds cause ear infections, and you’ll catch a cold from going out with wet hair
