7. You are more likely to catch a cold if you are cold.
It seems like an obvious conclusion: the warmer you dress, the less likely you are to catch a cold. However, experts say that bundling up before venturing outside in cold weather is absolutely unnecessary. Apparently there has even been a study to find out if going outside with wet hair increases your chance to get sick – and it turns out that it doesn’t. You will be feeling cold, but that doesn’t influence your immune system.
What’s more, during winter you are more likely to catch a cold while indoors. When we crank up the heating, it dries up the mucous membranes in our noses, causing small cracks and making the surface more vulnerable to germs. Add to this the fact that in winter people tend to spend time indoors in large groups, and you will see why catching someone else’s cold in this way is a very real possibility.
