A new study reveals that a common household chemical, often found in cleaning products, may pose unexpected risks to human health when inhaled over prolonged periods. Researchers found evidence suggesting potential respiratory irritation and long-term damage to lung tissue, particularly in environments where ventilation is poor. The findings challenge previous assumptions about the safety of widely used disinfectants and could prompt a reevaluation of exposure guidelines. Experts warn that further investigation is needed to assess real-world risks for consumers.
