How to Prevent & Treat Colds & Flu

In this episode, I explain the biology of the common cold and flu (influenza) and how the immune system combats these infections. I describe behavior, nutrition and supplementation-based tools supported by peer-reviewed research to enhance immune system function and better combat colds and flu. I also dispel common myths about how the cold and flu are transmitted and when you and those around you are contagious. I explain if common preventatives and treatments such as vitamin C, zinc, vitamin D and echinacea work. I also highlight other compounds known to reduce contracting and duration of colds and flu.  I discuss how to use exercise and sauna to bolster the immune response. This episode will help listeners understand how to reduce the chances of catching a cold or flu and help people recover more quickly from and prevent the spread of colds and flu. Correction: I misspoke in the episode. A micron is 1/10,000 of a centimeter, not 1,000. Additionally, 1 millimeter equals 1/10 of a centimeter, not 1/100.
