Runny nose. Itchy, watery eyes. Sneezing. If you don’t have allergies, you probably know someone who does. The number of people with allergies, including food allergies and eczema, is increasing. What is going on? A medical anthropologist describes how our hygiene habits, our diets, and our polluted environment are irritating our bodies. Also, the case for skipping your shower. Is skin healthier when we stop lathering?
