The health of your family is at the mercy of the quality of the air you have in your home. Many people don’t know that outdoor air is a lot less polluted than indoor air. In fact, your indoor air could be up to five times more polluted than outdoor air. So when someone says they need to step out to get a breath of fresh air, they mean it.

Indoor air can be so polluted that the Environmental Protection Agency (EPA) ranks it in the top five environmental hazards. And just what can be found in the air in your home that makes the quality so bad? Pollen, mold, radon, pet dander and even formaldehyde are regularly found in many homes across the country.

When it comes to air quality, humidity is also a concern. Air that is too dry or too humid can have negative effects on your health and it can also damage your home.

One of the leading causes of disability worldwide is depression. Depression has become a serious health condition that many people suffer and that can lower the quality of life. Depression is associated with life events and genetics, but it can also be tied to the air you breathe.

Risk factors for depression can be difficult to pinpoint, but research has found a strong correlation between depressive symptoms and air pollution. They think it might have to do with the inflammatory response that happens when people are exposed to environmental toxicity.

The Yale School of Public Health did a study and found that an increase in air pollution was linked to an increase in depression. They conclude that reducing indoor air pollution can be a way to lessen the severity of depression.

Weight Gain

If you have been gaining weight and cannot understand why because you follow a strict diet and you get plenty of exercise, indoor air pollution might be to blame.

A study found that two groups of rats who were served the same diet but in two different environments had results that were quite surprising. The group of rats that were exposed to polluted air gained more weight than the rats that breathed clean air. These results implicate the same outcomes for humans.


As allergens find their way into your home, it is likely you will suffer the symptoms of allergies. It is estimated that one in five Americans will experience an illness directly linked to allergies. Even if you don’t suffer an allergy-related illness, you can still suffer the symptoms of allergies including sneezing, running nose, headaches, swelling and fatigue.

Studies show that indoor allergens come into your home through various household items like cleaning products. Your home also likely contains outdoor allergens that force their way in.

Cardiovascular Disease

According to the American Heart Association, someone in the United States will die from cardiovascular disease every 40 seconds. This is an alarming statistic that sheds light on just how dangerous cardiovascular disease is. What’s even scarier is that indoor pollution could be a contributing factor to cardiovascular disease.

Pollutants that are very small aren’t easily partitioned and can be more easily digested by the human body. This can lead to irritation of the lungs, blood vessels and around the heart.

Autoimmune Diseases

Autoimmune diseases are characterized as a response within the body that leads to the destruction of your own organs and tissues. There is a Canadian study that suggests the increase of this disease in North America can be attributed to indoor air pollution.


It is estimated that up to 30 percent of all respiratory diseases are a result of indoor air pollution. This makes perfect sense as inhalation is the key passageway for air pollutants. Air pollutants find their way into your indoor air and can lead to respiratory problems.

How Indoor Air Pollution Affects Children

Your indoor air quality has a profound impact on the health of your children. Your children’s safety should be a parent’s first priority and you should have your home checked for pollutants on a regular basis.

It is also recommended that you check your child’s breathing often as it is important to notice any changes. If your children are breathing toxins, they could develop any number of respiratory diseases or other problems. For example, studies have shown that polluted air leads to an increased risk of bronchitis. And a child who is exposed to indoor air pollutants is more likely to need hospitalization because of an infection in their respiratory system.
