Indoor Air Quality: How Your Home Air Affects Your Health

When you think about air pollution, you probably picture smog or traffic. But indoor air quality, the cleanliness of the air inside buildings where people live and work. Also known as indoor air pollution, it can be two to five times worse than outdoor air—sometimes even more. You spend up to 90% of your time indoors. That means the air in your home, office, or bedroom is directly shaping how you feel, sleep, and even how your lungs and heart function over time.

It’s not just dust. air pollutants, harmful substances released into the air inside enclosed spaces come from everyday sources: cleaning sprays, new furniture, paint, candles, even your dryer vent. VOCs, volatile organic compounds that evaporate at room temperature and can irritate the eyes, nose, and throat are hiding in your laundry detergent and air fresheners. Mold grows in damp bathrooms. Carbon monoxide leaks from old heaters. Pet dander and dust mites cling to carpets and bedding. These aren’t just annoyances—they’re silent health risks linked to asthma, headaches, fatigue, and long-term lung damage.

ventilation, the process of replacing stale indoor air with fresh outdoor air to reduce pollutant buildup is your first line of defense. Opening a window for 10 minutes a day helps. Using exhaust fans in kitchens and bathrooms cuts moisture and fumes. Air purifiers with HEPA filters catch particles you can’t see. But no gadget replaces good habits: fixing leaks, choosing low-VOC products, cleaning regularly, and keeping humidity below 50%.

Some people notice symptoms right away—coughing, itchy eyes, stuffy nose. Others don’t feel anything until years later. That’s why indoor air quality matters even if you feel fine. It’s not about being allergic. It’s about reducing the total load on your body. Every breath you take indoors should be clean, not a slow drip of toxins.
