During cooler months, the dry air sucks moisture out through my top layer, which makes me irritated. Literally. Dryness triggers an inflammatory response: Immune cells as well as pro-inflammatory proteins and other enzymes go wild, activating itch receptors that send signals to your brain. I know it feels good for a second—scratching may engage pleasure and reward centers in the brain. But if you keep at it, I’ll get even more inflamed, which will cause those itch receptors to refire. And a vicious circle continues. All. Winter. Long. These are surprising signs of disease that your skin can reveal.
