Outdoor air pollution – that toxic mix of particulate matter, biological materials, and chemicals that react with each other in the air is a big public health issue around the globe.
Poor air quality has been identified as a primary contributor to chronic diseases, hospitalization rates, and even premature death. The World Health Organization (WHO) has estimated that air pollution causes as many as 2 million premature deaths around the globe every year.
Big cities are often blamed for having the worst air quality: Hong Kong, Delhi, Manila, Cairo, Mexico City and Santiago are among a few, but smog also affects rural areas depending on the current geographic landscape and weather patterns. If high-polluting industries, such as refineries, mines, heavy manufacturing and smelting, are nearby, the air quality is often significantly reduced.
No matter where you go in the world, you won’t be able to completely escape air pollution because emissions in one country travel to others due to weather patterns. The length of exposure and the concentration of pollutants will also have an important impact on your health when you travel.
See the following air quality tips for travelers.
What are the symptoms a traveler should recognize when they are suffering from poor air quality? The short-term symptoms of exposure to poor air quality include:
The long-term effects include lung cancer, cardiovascular disease, chronic respiratory illness, and the development of allergies. Air pollution is also associated with heart attacks and strokes.
Some personal factors have a big affect on how poor air quality affects a particular traveler. These include:
A traveler’s current health
Allergies, heart and lung diseases, bronchitis, asthma are all health concerns that could affect your body reacts to poor air quality.
A traveler’s destination
If you are headed to an urban area or one known for poor air quality and/or lack of rain, then you may be headed for an area with poor air quality.
A traveler’s age
Elderly people and young children are more susceptible to having problems with poor air quality. The elderly often have pre-existing medical conditions and younger people take in more air – and therefore a higher level of pollutants – due to their lower body weight.
The length of a trip and the season of the year also affect how much a traveler’s body reacts to poor air quality. A shorter trip means less air breathed and fewer pollutants inhaled, for example. Seasonal weather patterns also affect air quality in certain parts of the world.
Industrialized countries have long worked to reduce levels of noxious gases, sulfur dioxide, smog, and smoke in order to improve people’s health.
