5 Hidden Dangers of Indoor Air Pollution

Contrary to what many people believe, indoor air isn't always cleaner than outdoor air. According to the Environmental Protection Agency (EPA), in fact, the air inside most residential homes and buildings is up to five times more polluted than outdoor air. When compared to outdoor air, indoor air typically contains higher concentrations of pollutants like dust, dirt, mold, viruses and bacteria. So, what are the dangers of indoor air pollution?

#1) Allergies

Indoor air pollution can trigger allergy attacks. Millions of people suffer from respiratory allergies. If they inhale a particular substance, they may experience an allergy attack that's characterized by sneezing, red and itchy eyes, nasal congestion, headache and other symptoms. People who suffer from respiratory allergies must use caution to avoid indoor air pollution. Otherwise, the airborne pollutants could trigger an allergy attack when inhaled.

#2) Cold and Flu Infections

Even if you don't suffer from respiratory allergies, you should try to avoid indoor air pollution so that it doesn't lead to a cold or flu infection. Indoor air pollution can increase the risk of cold and flu infections. While you can catch a cold or flu in any environment, the risk of transmission is oftentimes greater in residential homes and buildings with polluted air. As the indoor air becomes more polluted, the high concentration of germs may result in infection.

#3) Dry Skin

You might be surprised to learn that indoor air pollution can cause dry skin. For healthy skin, you must keep it moist. There's typically an adequate amount of moisture in the air to protect against dry skin. In cases of high indoor air pollution, though, small particulate matter -- such as dust -- will settle on your skin where it absorbs and retains moisture. Over time, this can lead to severely dry skin.

#4) Increased Risk of Cancer

Some types of airborne pollutants are carcinogenic, meaning they have the potential to cause or contribute to cancer. The World Health Organization (WHO) even published a report describing  indoor air pollution as a major risk factor for cancer. Unless you're willing to take that risk, you should avoid exposure to indoor air pollution.

#5) Fatigue

Research has shown a correlation between indoor air pollution to fatigue, specifically chronic fatigue. If you are constantly exposed to indoor air pollution, you may experience low energy levels. Many of airborne pollutants can interfere with your body's metabolic processes, resulting in fatigue.
