UPDATE: As families adjust to the back-to-school rush, new findings reveal a critical health risk lurking in homes across Canada and the U.S. Health Canada reports that Canadians spend approximately 90 percent of their time indoors, raising urgent concerns about indoor air quality as cold and flu season approaches.

Just announced: The US Environmental Protection Agency (EPA) warns that indoor pollutant levels can be significantly higher than those found outdoors, making it essential for households to understand and address these hidden dangers.

Health experts stress that increased indoor time during autumn elevates the risk of respiratory illnesses, with a direct correlation between indoor air pollutants and viruses such as influenza and respiratory syncytial virus (RSV). Dr. Alison Danby, a naturopathic doctor specializing in immune health, emphasizes that “your immune system isn’t just fighting viruses—it’s reacting to chemicals, mold, airborne particles, and environmental toxins.”

Why this matters: As respiratory illnesses surge, families must take immediate action to protect their health. Dr. Danby warns that exposure to indoor pollutants can lead to chronic immune dysregulation and increased inflammation, significantly affecting overall health.

What to watch for: Below are the top hidden threats lurking in many homes, along with recommended remedies to safeguard your family’s health:

1. Mold: Commonly found in water-damaged walls, HVAC systems, and damp basements, mold disrupts immune function and can exacerbate conditions like asthma. Health risks include rhinitis, sinusitis, and irritable bowel disease.
Remedy: Maintain indoor humidity between 35 and 50 percent, use dehumidifiers, and promptly address leaks.

2. Volatile Organic Compounds (VOCs): Present in cleaning sprays, air fresheners, and new furniture, VOCs can trigger inflammation and impair immune function.
Health consequences: Long-term exposure is linked to diabetes and cardiovascular disease.
Remedy: Choose fragrance-free products and ensure proper ventilation.

3. Nitrogen Dioxide (NO2) and Particulate Matter (PM2.5): Emitted from gas stoves and fireplaces, these pollutants can damage lung function and are associated with chronic respiratory issues.
Remedy: Use exhaust fans while cooking and consider electric appliances to minimize emissions.

4. PFAS (Forever Chemicals): Found in nonstick cookware and food packaging, PFAS can interfere with immune responses and increase systemic inflammation.
Remedy: Replace nonstick items with safer alternatives and avoid fast food packaging.

Dr. Danby alerts that just minutes of gas stove use can raise indoor NO2 levels beyond safe limits, with a 2022 report estimating that 12.7 percent of childhood asthma cases in the U.S. may be linked to gas stove use.

Final thoughts: As we enter the colder months, families are urged to prioritize indoor air quality. The health impacts of these hidden threats can be severe, especially for children and those with pre-existing conditions. Taking proactive measures now can fortify your family’s defense against the impending cold and flu season.
