Dryer Sheets and Asthma: The VOC Connection
Do dryer sheets trigger asthma? Yes. Dryer sheets are a major source of Volatile Organic Compounds (VOCs) and respiratory irritants known as Quaternary Ammonium Compounds (Quats). When heated, these chemicals aerosolize and are vented directly into the air you breathe. A landmark study found that dryer vents emit over 25 VOCs, including acetaldehyde and benzene, which are known to irritate the lungs and trigger asthma attacks. For those with respiratory sensitivities, switching to wool dryer balls or a “fragrance-free” home is a critical step in improving indoor air quality.
