The lungs are the central part of the respiratory system. Located in the chest or the thoracic cavity, they make oxygen available to the body and release carbon dioxide. For overall health, good lung function is vital. However, several daily household factors can contribute to lung damage. While some risk factors may be unavoidable, basic knowledge and prevention of these threats can help reduce the risk of lung diseases and promote better health. Mold Mold is a type of fungus that reproduces using spores. It releases spores into the air, which can cause severe lung damage for those with mold allergies, COPD, and a weak immune system. People sensitive to mold must fix leaks around their homes and avoid the buildup of leaves and compost piles to discourage mold growth. Carpet The little crevices in carpet fabric can trap mold, cockroach droppings, dust mites, and toxic gasses, making them a health hazard. If possible, switch to wood, marble, or tile floors. Alternatively, opt for rugs that can be cleaned outside the home. Vacuum the carpet three times a week, and have it steam cleaned annually. Gas appliances Gas appliances such as cooktops, space heaters, and ovens could also contribute to lung damage, as when gas, wood, oil, coal, and kerosene burn, they release nitrous oxide.
