Stay indoors and limit physical activity during high pollution
Mexico City has been taking steps to improve its air quality, but it's still a highly polluted city. To protect yourself from the pollution, it's advisable to stay indoors and limit physical activity during periods of high pollution. Here are some measures you can take:
Check the air quality index: Mexico City has an air quality forecasting system that alerts the public to high pollution events 24 hours in advance. Check the Índice Metropolitano de la Calidad del Aire (IMECA) index to assess the level of pollution and the associated health risks. During periods of high pollution, it's best to minimise your time outdoors.
Improve indoor air quality: When outdoor pollution levels are high, it's important to limit your exposure to indoor air pollutants as well. Indoor air quality can be impacted by various sources, including outdoor air infiltration, inadequate ventilation, and indoor pollution sources. Try to reduce indoor activities that generate pollutants, such as cooking, painting, or using certain cleaning products. If possible, use exhaust fans in the kitchen and bathroom to remove contaminants directly from those rooms.
Ventilate when safe: While it's generally recommended to ventilate indoor spaces by opening windows and doors, this may not always be advisable during high pollution levels. Check outdoor conditions, and if pollution levels are extremely high, keep windows and doors closed to prevent outdoor pollutants from infiltrating your indoor space.
Consider air purification: Table-top air cleaners may be useful in conjunction with efforts to remove pollution sources. However, their effectiveness can vary depending on the strength of the pollutant source and the size of the space. Maintaining these devices according to the manufacturer's directions is crucial for long-term performance.
Limit physical activity: During periods of high pollution, it's best to avoid strenuous physical activity, especially outdoors. Physical exertion increases the amount of air inhaled, leading to a higher intake of pollutants. If you must exercise, try to do so indoors with the windows closed, or consider low-intensity activities that don't require deep breathing.
By following these measures, you can reduce your exposure to harmful pollutants during periods of high pollution in Mexico City. Staying indoors and limiting physical activity are crucial steps to protect your health when outdoor air quality is poor.

Wear a face mask to protect your lungs
Mexico City has long struggled with air pollution, but the government has successfully implemented various initiatives to improve air quality. Despite this, the concentration of airborne particles still exceeds the World Health Organization's guidelines. Therefore, it is important to take measures to protect yourself from air pollution when in Mexico City. One way to do so is by wearing a face mask.
When choosing an air pollution face mask, it is important to select one that is breathable. This is particularly important if you plan to engage in outdoor exercise or wear the mask for an extended period. A good mask should have a tight seal to prevent leakage and protect you from airborne particles. It should also have comfortable straps to ensure the seal around your nose and chin is airtight while preventing pain or discomfort.
It is recommended to opt for masks that are tested for 95% efficacy against airborne particles, such as KN95/FFP2 masks. These masks can filter out allergens, airborne viruses, and wildfire smoke. N95 masks are also effective, but their valves emit exhaled respiratory aerosols, which can be a concern if you are infected. If you are concerned about sunlight exposure, consider masks with UPF 50, which provides the highest possible protection against UV rays.
Some masks, like the Airinum Urban Air Mask 2.0, have adjustable ear loops and head straps to relieve pressure on the ears during long-term use. This mask also has a dual exhalation valve ventilation system to keep the air inside the mask comfortable. It is tested to filter 98-99.99% of particles down to the size of 0.3 μm and is certified for international pollution mask standards.
In conclusion, wearing a face mask is an effective way to protect your lungs from air pollution in Mexico City. When selecting a mask, consider its breathability, seal, efficacy against airborne particles, and additional features like UV protection and valve systems.
