Have you ever wondered what happens to the chemicals inside your home once they leave the bottle… or the carpet, paint, or sofa? Dr. Charles Weschler joins us to unpack the surprising science of indoor chemistry, revealing how modern materials quietly release volatile organic compounds (VOCs) into your home’s air, onto dust, and even through your skin. He explains how post–World War II innovations such as synthetic compounds, polymers, and chemical additives found in everything from carpets to cleaners to flame retardants can contribute to indoor air pollution and affect your health. Dr. Weschler offers simple, science-backed strategies to minimize exposure, while warning against chemical-producing cleaning devices that may do more harm than good. Tune in to discover how small changes in your cleaning habits and home environment can lead to big improvements in your indoor air and your health.
