With humor and scientific rigor, Maël Lemoine untangles fact from falsehood when it comes to colds and cold weather.

This concise book sheds light on the real effects cold has on our bodies and the limits of modern medical science, at last answering the question: can you walk barefoot on a cold tile floor without getting sick?
