House Dust Allergy

Your nose runs, your eyes itch, your throat scratches — and not out in the spring air, but at home. In your own bed. On your own sofa. House dust mites are everywhere; they belong to life the way bacteria belong to skin. But your immune system treats them like intruders. It reacts to something harmless as though it were a threat. And the paradox: the place where you should feel safest — your home — becomes the place where your body sounds the alarm.

Medically, the matter is clear: an overreaction of the immune system to protein components in mite feces. But BodySignal asks deeper: why does your body react precisely to the dust of your own living space? What is it about your own surroundings — about yourself — that you cannot bear?

Dust is what settles when you live. It is unavoidable. It is normal. And yet your body treats it as an enemy.
