A new study reveals how a common household chemical found in many cleaning products may pose unexpected risks to human health, particularly when used in poorly ventilated spaces. Researchers identified potential respiratory and skin irritation effects linked to prolonged exposure, raising concerns among health experts about indoor air quality. The findings suggest that even low concentrations of the substance could contribute to long-term health issues, prompting calls for better labeling and safety guidelines. Public health officials are now urging consumers to take precautions when using products containing the chemical.
