Is it rare to be allergic to dust mites?
Not at all. Here’s why: Dust mites poop — a lot. A single dust mite poops out around 20 droppings each day, and despite the incredibly small size of dust mite feces, it’s a highly potent allergen for 25 percent of the population.
But it’s not just dust mite poop that can trigger allergies. Dust mites only live for one to three months, and once they die, their dried-up body parts are also highly allergenic.
Inhaling the dead bodies and dookie of dust mites may trigger mild or severe allergies, asthma attacks, and eczema flare-ups. People with long-term dust mite allergies may develop asthma.
