Story at-a-glance Dryer sheets emit toxic chemicals like benzene and acetaldehyde, which pose cancer risks, irritate skin, disrupt hormones and harm brain health through inhalation or direct contact Synthetic fragrances in dryer sheets trigger allergic reactions, asthma and neurological symptoms like brain fog, especially in those with chemical sensitivities or underlying health conditions Dryer sheets leave behind residue that clogs lint screens, damages sensors, reduces efficiency and even increases the risk of dryer fires if not properly cleaned These products also degrade clothing, especially towels and athletic wear, by coating fabrics with a waxy film that reduces absorbency and impairs moisture-wicking properties Safer alternatives include organic wool dryer balls, white vinegar with essential oils, aluminum foil balls, air-drying and fragrance-free detergents to protect your health and home
