The Air Quality Health Index (AQHI) is a tool that measures air quality in terms of your health.
Those who are at risk of increased health problems with increasing air pollution are:
- People with diabetes, lung disease (such as chronic bronchitis, asthma, emphysema, lung cancer) or heart disease (such as angina, a history of heart attacks, congestive heart failure, arrhythmia or irregular heartbeat).
- Seniors because of weakening of the heart, lungs and immune system and increased likelihood of health problems such as heart and lung disease.
- Children because they have less-developed respiratory and defense systems. Children also spend more time outdoors being physically active, which can increase their exposure to air pollution.
- People participating in sports or strenuous work outdoors because they breathe more deeply and rapidly, allowing more air pollution to enter their lungs. They may experience symptoms like eye, nose or throat irritation, cough or difficulty breathing when air pollution levels are high.
