Your Body Is Speaking
Where metal touches your skin, it starts to fight back. Redness, itching, small blisters — sometimes within hours, sometimes only after days. The belt buckle leaves a red imprint. The trouser button burns against your skin. Earrings that others wear without a second thought turn into tiny sites of inflammation on you. Your body reacts to nickel — a metal found in almost everything: jewelry, watches, zippers, coins, door handles.
Medically, nickel allergy is a delayed-type contact allergy. The immune system identifies nickel ions as a threat and launches an inflammatory response — precisely where the metal touches the skin. But the psychosomatic question goes deeper: why does your body react so intensely to something that touches you from outside? What is it about this contact that your system reads as an attack?
