The smoke from cooking fires, stoves, and cigarettes is one of the primary air pollutants. This factor contributes to pneumonia, stroke, lung cancer, and heart disease. To stay safe, clean your chimney a few times a year. Keep your home well-ventilated by opening the windows several times a day. Refrain from smoking indoors. Mold The bathroom and kitchen provide perfect conditions for mold growth. This pathogen loves warm, dark environments, such as the sink and shower curtains. Exposure to mold can trigger or worsen existing health conditions. It has been linked to eye and skin irritation, difficulty breathing, and lung disease. If you notice mold in your home or office, remove it immediately. Pay special attention to cooking and shower areas. Fix any leaking pipes or clean the air ducts regularly. Asbestos When most people ask what causes indoor air pollution, they rarely think of asbestos. Yet, this toxic material is still found in millions of buildings. Back in the '70s, asbestos was widely used in the construction industry. Even though it has been banned, older establishments may contain traces. Ceiling tiles, fireproofing materials, and paints products are common sources of asbestos. This material could be present inside your walls or roofs as well. Air Fresheners Contrary to popular belief, air fresheners are anything but safe. These popular products contain toxic compounds known as phthalates. Studies have linked phthalates to reproductive disorders, birth defects, and hormonal imbalances. Moreover, these toxins affect airflow and cause respiratory diseases. Inkjet Printers This may come up as a surprise, but inkjet printers are a common cause of indoor air pollution. The printing inks contain glymes, which are toxic to your body. These chemical solvents are also used in carpet cleaners, brake fluid, and lithium batteries. Exposure to glymes has been shown to increase the risk of miscarriage, reproductive damage, and poor fetal growth.
