Dust mites and what they actually cause
Dust mites feed on shed skin cells and thrive at the humidity levels typical of a Long Island bedroom. They are not parasites and they do not bite, but their waste is one of the most common indoor allergens and it is concentrated exactly where your face spends eight hours a night. Morning congestion, itching eyes on waking, or symptoms that improve when you sleep elsewhere all point toward bedding rather than toward seasonal allergy.
