A new study reveals how a common household chemical, often found in cleaning products, may pose unexpected risks to human health when inhaled over time. Researchers found that exposure to the compound—even at levels considered safe for direct contact—could lead to respiratory irritation and potential long-term damage when breathed in repeatedly. The findings challenge existing safety standards and suggest that everyday consumer products might require reevaluation. Health experts are calling for further investigation into how these chemicals accumulate in indoor environments.
