Mold, Dust, and Indoor Air: Cleaning Up Your Child’s Environment

When we think about allergy triggers, it's easy to picture the outdoors — pollen drifting on the wind, grass underfoot. But for many children, indoor air quality plays just as large a role, if not larger, especially in a humid climate where mold and dust mites thrive year-round.

Where common indoor triggers tend to hide

• Mold — bathrooms, kitchens, basements, around windows, and anywhere moisture lingers
• Dust mites — bedding, pillows, upholstered furniture, carpets, and stuffed animals
• Pet dander — concentrated in the areas pets spend the most time, but capable of traveling throughout a home
• Pests — droppings and shed skin from cockroaches and rodents are well-documented asthma triggers, especially in humid climates

Practical steps that tend to help

Indoor mold above 10,000 spores/m³ is associated with asthma exacerbations and chronic cough

• Keep indoor humidity in a moderate range — a dehumidifier can help in consistently damp areas
• Address moisture problems quickly — leaks, condensation, and damp spots are where mold gets its start
• Vacuum regularly with a vacuum that has a high-efficiency filter, and wash bedding in hot water weekly
• Use allergen-proof covers on mattresses and pillows
• Change HVAC filters on a regular schedule, and consider higher-efficiency filters where appropriate
• Ventilate bathrooms and kitchens well, especially during and after activities that create humidity

You don't need to turn your home into a sterile environment — that's neither realistic nor necessary. The goal is simply to reduce the load of the specific triggers that affect your child the most, which an evaluation can help identify, so your efforts are aimed where they'll actually make a difference.
