• Keep your home contaminant-free. Chemical exposure can include lead, radon, pesticides, volatile organic compounds and tobacco smoke. Exposures to asbestos particles, radon gas, carbon monoxide and second-hand tobacco smoke are higher indoors than outdoors.
• Keep your home ventilated. Studies show that increasing the fresh air supply in a home improves respiratory health.
• Keep your home maintained. Poorly maintained homes are at risk for moisture and pest problems. Deteriorated lead-based paint in older homes is the primary cause of lead poisoning in children.
