People often purchase humidifiers, carpets, and other products to keep their homes clean and fresh. However, not all of these are as harmless as they seem. Some household products can lead to lung conditions like chronic obstructive pulmonary disease (COPD) when not handled or used correctly. Therefore, one must take every precaution to protect one’s respiratory well-being. Here are a few household products that can harm the lungs and increase the risk of COPD. Humidifiers Humidifiers help moisten dry indoor air and relieve respiratory symptoms and dry skin. However, they can become breeding grounds for harmful bacteria and mold if not cleaned regularly. When turned on, the machine can release these pathogens into the air, which one may inhale. Studies suggest inhaling mold may worsen breathlessness and related COPD symptoms. Therefore, those diagnosed with or at risk of this condition should clean the humidifier regularly by following the manufacturer’s instructions. Experts also suggest using distilled water to minimize the risk of contamination. Flour While flour is a staple in many kitchens, it can affect lung health when mishandled. When flour is poured or mixed vigorously, fine particles become airborne and can be inhaled. For individuals with sensitivity or allergies, this can lead to respiratory irritation.
