Health Effects of Indoor Air Pollution
Health Effects, diseases, symptoms of Indoor Air Quality Pollution, Contamination
The effects of indoor air pollutants range from short-term effects - eye and throat irritation -
to long-term effects - respiratory disease and cancer. Exposure to high levels of some pollutants,
such as carbon monoxide, can even result in immediate death. Also, some indoor pollutants can
magnify the effects of other indoor pollutants. Based on cancer risk alone, federal scientists
have ranked indoor air pollution as one of the most important environmental problems in the
United States.
Common symptoms of Indoor Air Pollution
Symptoms of poor indoor air quality are very broad
and depend on the contaminant. They can easily
be mistaken for symptoms of other illnesses such
as allergies, stress, colds and influenza. The most
common symptoms are:
- coughing
- sneezing
- watery eyes
- fatigue
- dizziness
- headaches
- upper respiratory congestion
If you notice relief
from your symptoms soon after leaving a particular
room or building, your symptoms may be caused
by indoor air contaminants.
Respiratory Health Effects
Consult the EPA's Health Effect Symptom Reference Chart
to determine the cause of the particular health effect:
- Rhinitis, nasal congestion (inflammation of the nose, runny nose)
- Epistaxis (nose bleeds)
- Dyspnea (difficulty of breathing or painful breathing)
- Pharyngitis (sore throat), cough
- Wheezing, worsening asthma
- Severe lung disease
More Severe Health Effects
Consult the EPA's Health Effect Symptom Reference Chart
to determine the cause of the particular health effect:
- Conjunctival (eye) irritation
- Rashes
- Fever, chills
- Tachycardia (rapid heartbeat, sometimes leading to shortness of breath)
- Headache or dizziness
- Lethargy, fatigue, malaise
- Nausea, vomiting, anorexia
- Myalgia (muscle pain)
- Hearing loss
- Environmental Tobacco Smoke
Asthma, frequent respiratory infections, repeated pneumonia, bronchitis, snoring, lung cancer,
impaired breathing, lung diseases, aggravation of existing respiratory and cardiovascular disease, changes to the body's immune system, and lowered defenses against inhaled particles
