What You'll Learn
Check the Air Quality Index (AQI) before exercising outdoors
Air pollution can have a significant impact on your health, especially if you have pre-existing respiratory or cardiovascular conditions. Therefore, it is important to check the Air Quality Index (AQI) before exercising outdoors. The AQI is a science-based guide that provides a colour-coded chart with pollutant-specific recommendations and precautions based on current or forecast air quality. The AQI typically ranges from 0 to 500, with higher values indicating greater levels of air pollution and associated health risks.
When checking the AQI, it is important to note the levels that may impact your outdoor exercise routine. Generally, an AQI between 0 and 50 is considered "satisfactory," posing minimal risks from air pollution. Moderate AQI levels, ranging from 51 to 100, are mostly acceptable, but individuals with chronic health conditions or increased sensitivity to pollution should be cautious. At these levels, it is recommended to opt for lower-intensity workouts and consider exercising in areas with lower pollution, such as nature trails or green spaces.
If the AQI reaches "unhealthy" levels of 101 and above, it is no longer encouraged to exercise outdoors. In such cases, it is advisable to switch to indoor exercises or opt for indoor venues with proper ventilation and air purification systems. It is worth noting that exercising indoors during high pollution levels can still result in exposure to particulate matter, especially if windows and doors are open. Therefore, checking the indoor air quality and taking appropriate measures, such as using air purifiers, is essential.
While physical activity is crucial for maintaining health, it is important to consider the potential risks associated with air pollution. By checking the AQI and following expert recommendations, you can make informed decisions about the intensity and location of your workouts to minimise the negative impacts of air pollution on your health. This is especially important for individuals with pre-existing health conditions or those who are unusually sensitive to air pollution, as the risks associated with exercising in polluted areas can be more severe.

Avoid exercising near busy roads
Exercising in polluted air can have negative health effects, especially for those with pre-existing respiratory or cardiovascular conditions. While physical activity is generally beneficial for health, air pollution can increase the risk of cardiovascular and non-communicable diseases, mainly of cardiorespiratory origin.
When exercising in a city, it is best to avoid busy roads as air pollution levels are higher in these areas. Studies have shown that pollution levels drop as you move away from busy roads, so consider quieter, low-emission parallel roads or parks for your workout. If you are cycling, jogging, or walking, be mindful of the proximity to vehicles as you will breathe in very high levels of harmful pollutants from their emissions.
If you live in an area with poor air quality, try to find locations with lower pollution levels, such as nature trails or parks. You can also opt for lower-intensity workouts, as higher-intensity exercises like long runs or sprinting increase your breathing rate and the amount of unhealthy air inhaled. Additionally, consider exercising indoors with an air purifier or checking local air quality forecasts to plan your outdoor workouts during cleaner air days.
Remember, environmental and lung health experts advise that the health risks associated with exercising in polluted air are generally less significant than the risks of an inactive lifestyle. However, it is essential to be mindful of air pollution levels and make informed decisions to protect your health.

Wear a mask while exercising
When exercising in a polluted area, wearing a mask can be beneficial for protecting yourself from inhaling harmful pollutants. The type of mask you choose is important, as some masks can increase the resistance of your breathing, making it harder to breathe and requiring more energy. For example, surgical masks and FFP2/N95 respirators have been shown to significantly decrease VO2 levels, oxygen uptake, and end-tidal partial pressure of oxygen, while increasing carbon dioxide production and dyspnea (difficulty breathing).
Cloth masks, on the other hand, have been found to have little to no effect on these respiratory parameters. It is worth noting that wearing a mask during exercise may also increase your perception of how difficult the workout is, as well as increase feelings of fatigue and thermal sensation. This is likely due to the increased resistance and decreased oxygen intake associated with mask-wearing.
However, if you are in an area with high levels of pollution, particularly particulate matter (PM2.5 or PM10), wearing a mask can help reduce the amount of pollutants you inhale. This is especially important if you are performing high-intensity exercises, as the body requires more oxygen during these types of activities. If you have weak respiratory muscles or underlying respiratory issues, wearing a mask during exercise may not be advisable, as it could potentially do more harm than good.
Additionally, it is crucial to invest in a high-quality mask that is designed to filter out pollutants. Cheap masks that do not effectively filter pollutants will only impede your breathing without providing any protection from pollution. Overall, while wearing a mask during exercise in polluted areas can be beneficial, it is important to consider the potential impacts on your breathing and oxygen intake, as well as the quality of the mask you are using.
