Limit outdoor activities when air quality is poor
When the air quality is poor, it is best to limit outdoor activities and stay indoors to protect your health. The Air Quality Index (AQI) is a valuable tool that can help you understand the severity of air pollution and make informed decisions about spending time outdoors.
The AQI is a rating system that measures five major pollutants: ground-level ozone, particulate matter (PM2.5), carbon monoxide, nitrogen dioxide, and sulfur dioxide. The ratings are presented on a scale from 0 to 500, with a lower number indicating better air quality. An AQI value under 50 is generally considered good air quality and safe for everyone to spend time outdoors without significant health risks.
However, when the AQI is in the yellow to red range (between 150 and 200), it is recommended to limit your time outside and avoid strenuous outdoor activities. If you have any underlying health conditions or sensitivities, it is best to stay indoors during this time. Moving your workouts indoors, such as walking in a shopping mall or using a gym, can help you stay active while avoiding poor air quality outdoors.
Additionally, be mindful of high-traffic areas and busy highways, as vehicle emissions can create high pollution levels nearby. Even if the overall air quality in your area is moderate, avoiding these locations can reduce your exposure to harmful pollutants.

Avoid exercising near high-traffic areas
When exercising outdoors, it is important to be mindful of the air pollution levels in your area. Air pollution tends to be at its highest on hot, sunny days, and near busy roads or highways, especially during rush hour. The vehicles on these roads emit pollutants such as particulate matter and gases like ozone, nitrogen dioxide, and sulfur dioxide, which can be harmful when inhaled.
To protect yourself from polluted air, it is recommended to avoid exercising near high-traffic areas. Here are some tips to help you do that:
- Check air quality forecasts: Stay informed about the daily air quality forecasts in your area by checking local forecasts. Sources for this information include local radio and TV weather reports, newspapers, and websites like airnow.gov. The Air Quality Index (AQI) is a valuable tool that provides a rating of air quality, indicating when it is safe to spend time outdoors and when it is not.
- Plan your exercise routine: Use the information from the forecasts to plan your workouts. If the air quality is poor, opt for indoor exercises or choose a different time of day when the air quality is expected to improve. You can also alternate between outdoor and indoor exercises based on the daily air pollution levels.
- Choose alternative routes: If you enjoy outdoor walks, runs, or bike rides, consider choosing routes that are not near busy roads. Opt for quieter, less trafficked roads or paths, and maintain a safe distance from vehicles when possible. Remember that the pollution levels drop as you move farther away from the main flow of traffic.
- Consider the time of day: Avoid exercising outdoors during rush hour or times when there is a high volume of traffic on the roads. Plan your workouts for early mornings or evenings when traffic is lighter.
- Explore indoor options: If outdoor air pollution levels are consistently high in your area, consider joining a gym or finding indoor spaces where you can exercise. While indoor spaces can also have poor air quality due to various factors, they may offer a better alternative to heavily polluted outdoor environments.
By following these tips, you can minimize your exposure to polluted air during exercise and reduce the potential health risks associated with inhaling pollutants. Remember to also stay updated with the latest research and technologies that can help you make informed decisions about your health and well-being.

Use air purifiers and filters to clean indoor air
Air purifiers are a great way to improve the air quality in your home and protect yourself from polluted air. They are simple machines, essentially a fan and a filter, but they can capture airborne allergens like pollen and mould spores, as well as bacteria, viruses, and smoke.
When choosing an air purifier, consider the size of the space you want to purify. Some purifiers are designed for small spaces like bedrooms and offices, while others are meant for larger living spaces. The Coway Airmega AP-1512HH Mighty, for example, is powerful enough for a large room and quiet enough to run at night. It's also durable and inexpensive, making it a top choice for many. Other options include the IQ Air Atem X, the Briiv 2 Pro Air Filter, and the Airdog X5, the first washable filter air purifier.
It's important to note that air purifiers are not a cure-all. They are ineffective against volatile organic compounds (VOCs) like cooking and pet odours, and they have no impact on carbon dioxide. In these cases, it's best to ventilate your space by opening a window. Additionally, an air purifier won't remove particulate matter that has settled on surfaces; a vacuum cleaner or dust mop is needed for that.
To maintain your air purifier, keep it on a moderate setting and run it continuously. If your purifier has a prefilter, be sure to clean or replace it regularly, as this is essential for keeping the purifier running well. Many purifiers also have an ionizer, but it's recommended to keep this feature turned off, as it may produce ozone, which can be harmful.
By using air purifiers and taking care of them properly, you can effectively clean your indoor air and create a healthier environment for yourself and your family.

Reduce indoor pollution by avoiding candles and gas stoves
Burning candles and using gas stoves are two common ways we inadvertently pollute the air inside our homes. Taking steps to reduce indoor pollution can help protect your household from the potential harms of poor air quality.
Candles, especially those made from paraffin, release pollutants and toxins into the air. A 2001 report by the Environmental Protection Agency (EPA) found that burning candles in enclosed spaces caused indoor air lead concentrations to exceed EPA recommendations. The lead is typically found in the soot that comes from the metal-core wicks. Synthetic fragrances in candles, particularly those that are paraffin-based, are the most harmful, emitting volatile organic compounds (VOCs) such as toluene and benzene, which have been linked to cancer.
To reduce indoor pollution from candles, opt for beeswax or soy candles, which produce fewer pollutants and burn cleaner than paraffin candles. Beeswax candles, in particular, burn slowly and evenly, leaving no inorganic byproducts or chemicals. They also release a slight honey fragrance and emit a golden bright light. When burning candles, ensure proper ventilation and trim the wick to reduce soot.
Gas stoves are another significant source of indoor air pollution. Cooking with gas stoves releases nitrogen dioxide and additional tiny airborne particles known as PM2.5, both of which are lung irritants. A study by researchers at Stanford found that the emission of nitrogen dioxide from certain gas burners or ovens quickly rose above the standard set for outdoors by the EPA. Gas stoves also introduce other toxic chemicals into homes, such as benzene, hexane, and toluene, which have been linked to asthma, cancer, and other illnesses.
To mitigate the impact of gas stoves on indoor air quality, ensure proper ventilation by opening windows or using exhaust fans while cooking. Regularly maintain and check your gas stove for efficient combustion, and consider switching to an electric stove, which has been shown to improve indoor air quality.
