What you need to know about Air Quality and your Health
August 10th, 2010Poor air quality in your city can lead to health problems or exacerbate pre-existing respiratory conditions. Air pollution is made of chemical and biological agents in the air that cause harm to our health or the environment. Sources include factories, burning of fossil fuels, car exhaust, and forest fires. If you suffer from the effects of bad air quality, your doctor may prescribe medications to help ease the symptoms or prevent serious medical attacks.
Bad air pollution can damage the sensitive respiratory system membranes, alveoli, and even your lungs. Common side effects of poor air quality include wheezing, coughing, and difficulty breathing. Some people may only experience acute symptoms, others may have to call in sick, others end up in the emergency room or admitted to the hospital, and a small group may die.
According to Health Canada, about 5,900 deaths in Canada each year are attributed to air pollution. These occur more often in higher risk groups including babies, children, the elderly, and those with pre-existing health conditions.
The Air Quality Health Index (AQHI) is a scale that measures the levels of pollution in the air and the risk they pose to humans. A rating from 1-3 is considered normal and low health risk to the population. Starting at an AQHI of 4-6 you can start feeling more severe symptoms, and more severe for the at-risk population. A High Risk (7-10) or a Very High Risk (10+) rating the at-risk population is usually urged to limit or eliminate any physical exertion outdoors.
When the AQHI is high you don’t want to be heading outside to the local grocery store or pharmacy to get your medication. Order it from an online Canadian Pharmacy, have it delivered directly to your door, and save a bundle doing it!
