Breathe Easy: Escape Air Pollution's Grasp

Air pollution is a serious global health problem, causing an estimated 4.2 million premature deaths worldwide in 2019. While effective policies to reduce emissions are the best way to tackle this issue, there are also individual actions that can be taken to reduce exposure and health risks. This includes limiting time spent outdoors, reducing physical exertion, using air filters, and staying informed about air quality alerts. In addition, individuals can reduce their contribution to air pollution by driving less, using energy-efficient appliances, and choosing eco-friendly modes of transportation.

Reduce vehicle usage, opt for eco-friendly travel, carpool, or use public transport

One of the most effective ways to reduce air pollution is to reduce vehicle usage. Vehicle exhaust is a major source of air pollution, and by driving less, you can significantly improve air quality. Consider opting for eco-friendly travel options such as biking or walking. These modes of transportation are not only good for the environment but also offer health benefits by providing an opportunity for physical activity.

Carpooling is another excellent way to reduce vehicle emissions and air pollution. By sharing rides with colleagues, neighbours, friends, or even using new online tools to find carpool partners, you can cut down on the number of cars on the road. Carpooling saves money, reduces traffic congestion, and fosters a sense of community. It can even lead to unexpected connections and social benefits, as evidenced by the story of Anne and Andrew, who found love while carpooling!

For longer distances or when carpooling is not an option, utilizing public transportation is a great alternative. Buses, trains, and subways emit less pollution per person than private vehicles, especially when they run on electricity or renewable energy sources.

Additionally, when purchasing a vehicle, consider choosing an electric or fuel-efficient model. Modern vehicles with advanced emissions reduction technologies, such as catalysts and electronic fuel injection, result in significantly less pollution. Keeping your car well-maintained is also essential; fix exhaust and oxygen sensor problems promptly and avoid unnecessary idling, as this wastes fuel and contributes to air pollution.

By implementing these changes, we can collectively make a significant impact on improving air quality and creating a cleaner, healthier environment for ourselves and future generations.

Limit outdoor exercise and physical exertion on high pollution days

Air pollution is a serious global public health problem. While it is important to remain physically active, it is also vital to consider the impact of the air you exercise in. When you are physically active, you breathe in more air, and particles can penetrate deeper into your lungs. Exposure to air pollution can negatively affect everyone, but it can be particularly harmful to people with lung conditions, older people, children, and babies.

On days when air pollution levels are high, it is advisable to limit outdoor exercise and physical exertion, especially if you are part of a vulnerable group. Vulnerable groups include children, older adults, people living with cardiovascular disease or diabetes, and people living with lung diseases such as asthma or chronic obstructive pulmonary disease (COPD). For those who are sensitive to air pollution, limiting outdoor activities on "code yellow" days is recommended, and shifting exercise indoors on "code orange" or higher days.

You can use local media, air quality apps, or websites to check the daily air quality index and air quality forecast. The Air Quality Index (AQI) provides information about exercising or engaging in physical activity when there is air pollution. If the air quality forecast predicts poor air quality, consider moving your exercise indoors or choosing a lighter activity. For example, instead of going for a long run, opt for a casual bike ride or a walk.

It is important to note that the decision to exercise outdoors during high air pollution levels depends on various factors, including the air pollution level, your health status, and the length and intensity of the exercise. If you have questions about whether you should exercise outside, consult your healthcare provider. They can guide you based on your individual circumstances and susceptibility to air pollutants.

Use energy-efficient appliances and heating systems, and conserve electricity

Energy efficiency is a critical component of reducing air pollution. By using less energy, we can lower energy costs and minimise the release of harmful air pollutants. Power plants emit pollutants such as nitrogen oxides, sulfur dioxide, and particulate matter, which contribute to unhealthy air quality.

You can start by choosing energy-efficient appliances and heating systems. Look for the ENERGY STAR label when purchasing new products. This government-backed symbol is the gold standard for identifying energy efficiency, indicating that a product uses less energy to achieve the same outcome. For example, an ENERGY STAR-certified heat pump water heater uses 70% less energy than a standard electric water heater, resulting in significant energy savings. Similarly, ENERGY STAR-certified light bulbs consume up to 90% less energy than incandescent bulbs, providing the same illumination.

Another way to conserve electricity is to be mindful of your daily habits. Turn off electrical appliances when not in use, and consider setting your thermostat a little higher in the summer and slightly lower in the winter. Additionally, try to combine errands to reduce trips and limit engine idling, especially when using a car.

Investing in energy-efficient products may sometimes come with a higher upfront cost. However, it is important to consider the long-term savings and environmental benefits. For instance, an energy-efficient electric heat pump water heater may cost more initially but can save a family of four over $550 per year in energy costs.

By adopting these practices and choosing energy-efficient appliances and heating systems, you can significantly contribute to reducing air pollution and protecting the environment.

Avoid backyard fires and use of gas-powered lawn and garden equipment

Backyard fires and gas-powered lawn equipment are significant contributors to air pollution. Smoke from burning wood is made up of a complex mixture of gases and fine particles, which are also called particle pollution or particulate matter. Particle pollution is especially harmful to children and teenagers, older adults, and people with heart or lung disease, including asthma and COPD. To reduce particle pollution, only burn seasoned, dry wood and avoid burning green wood, construction waste, plastic, garbage, or yard waste. Keep fires small and brief, and never start a fire during an air quality alert.

Gas-powered small engines like those on lawnmowers and leaf or snow blowers often lack pollution control devices. An hour of running a lawnmower can produce nearly the same amount of pollution as a 100-mile car trip. To reduce air pollution, switch to electric or hand-powered lawn and garden equipment.

Additionally, consider signing up for texts or emails about elevated air pollution levels and plant and care for trees, as they filter pollutants and absorb carbon dioxide.

Reducing air pollution from backyard fires and gas-powered lawn and garden equipment is essential for protecting public health and the environment. By following the above suggestions, individuals can play a crucial role in improving air quality and reducing the harmful effects of air pollution on vulnerable populations.

It is also important to note that air pollution is a complex issue that requires collective action and effective policies to reduce emissions at their sources. While individual actions are important, societal efforts are necessary to address the root causes of air pollution and implement long-lasting solutions.

Use air filters to clean indoor air

Air pollution is a serious issue, and it can be worrying to think about the impact it may have on your health. One way to reduce your exposure to air pollution is to clean the air inside your home with air filters.

The first step is to identify the sources of indoor air pollution. These can include outdoor sources, such as smoke from backyard fires, and indoor activities, like cooking, cleaning, and second-hand smoke. Other sources include building materials, consumer products, and home furnishings. Common indoor contaminants include particulate matter (PM2.5 and PM10), formaldehyde, mould, and pollen.

To improve your indoor air quality, you can use portable air cleaners, also known as air purifiers or sanitizers. These devices are designed to filter the air in a single room or area. They can reduce indoor air pollution, but it's important to note that they cannot remove all pollutants. When choosing a portable air cleaner, look for one that can filter out small particles of the greatest health concern, such as PM2.5. You can also upgrade the air filter in your furnace or central heating, ventilation, and air-conditioning (HVAC) system. HVAC filters are designed to filter the air throughout your home.

It's important to remember that filtration should supplement source control and ventilation. In addition to using air filters, you should also reduce or remove the sources of indoor air pollutants and ventilate your home with clean outdoor air. Regularly changing your air filters according to the manufacturer's recommendations is also crucial. Many factors can affect how quickly filters get dirty, but manufacturers typically recommend replacement every 60 to 90 days.

By following these steps and using air filters effectively, you can take control of your indoor air quality and reduce your exposure to air pollution.
