Well to answer that question let’s look at the conventional wisdom. If you ask just about anybody off the street, they’ll tell you that the cold somehow weakens your body (maybe your immune system) and makes you more susceptible to disease. How do they know this? Well their mothers told them, of course!
Your mother probably told you time and time again, “Bundle up or you’ll catch a cold!” But how accurate is this statement? After all, our bodies stay close to the same temperature no matter how cold it is outside. What is the real reason people get sick more in the wintertime?
