Yes, poor indoor air quality can significantly impact allergies. Allergens such as dust mites, pet dander, pollen, mold spores, and volatile organic compounds (VOCs) can become trapped indoors and circulate in the air. Breathing in these allergens can trigger allergic reactions in sensitive individuals, leading to symptoms like sneezing, coughing, congestion, itching, and watery eyes. Additionally, poor indoor air quality can worsen respiratory conditions such as asthma. To alleviate allergy symptoms, it is important to improve indoor air quality by regularly cleaning and vacuuming, using high-quality air filters, maintaining proper ventilation, controlling humidity levels, and considering the use of air purifiers.
