Wear a pollution mask with a carbon filter, exhaust valve, and N95 filter
Delhi, India's national capital, has the dubious distinction of being the most polluted city in the country. The air quality in Delhi is impacted by a range of factors, including vehicular emissions, large-scale construction, industrial waste, and the burning of crops and firecrackers during festivals. These sources contribute to high levels of dangerous pollutants in the air, such as particulate matter, gaseous air pollutants, and ground-level ozone.
To protect yourself from the harmful effects of air pollution in Delhi, it is recommended to wear a pollution mask with a combination of specific features. Here are some key considerations when selecting such a mask:
Carbon Filter: A carbon filter is an essential component of an effective pollution mask for Delhi's air. Carbon filters are designed to absorb and trap a wide range of airborne contaminants, including gaseous pollutants and odours. They are particularly effective against volatile organic compounds (VOCs) and can help reduce exposure to harmful gases commonly found in Delhi's air, such as carbon monoxide and nitrogen oxides.
Exhaust Valve: An exhaust valve is another important feature to look for in a pollution mask. This valve allows for directed outflow of breath, helping to reduce moisture buildup from condensation. It improves breathability and comfort, especially in hot and humid climates. However, it is important to note that masks with exhaust valves may release exhaled respiratory aerosols into the air, potentially spreading infectious particles. Therefore, caution should be exercised when using masks with exhaust valves around others.
N95 Filter: The N95 designation signifies that the mask can filter out at least 95% of airborne particles down to 0.3 microns in size. This includes fine particulate matter, which is a significant component of Delhi's air pollution. N95 masks are highly effective in reducing exposure to harmful pollutants and have been shown to significantly reduce carbon monoxide levels in exhaled breath. They offer better protection against coarse and fine pollution particles compared to surgical or fabric masks.
When choosing an N95 mask, ensure it has a good seal that conforms to the contours of your face. A tight seal is crucial to the mask's effectiveness, preventing the inflow of unfiltered air from the sides. Look for masks with high-quality sealing techniques, such as fabric or silicone, and ensure the mask fits perfectly. Additionally, consider masks with features that enhance breathability, especially if you plan to engage in high-intensity activities or exercises.
In conclusion, wearing a pollution mask with a carbon filter, exhaust valve, and N95 filter can provide significant protection against Delhi's air pollution. However, it is just one aspect of an overall strategy to cope with polluted air. It is also important to limit outdoor activities, use air purifiers indoors, and avoid high-intensity exercises during periods of high pollution. By combining protective measures, you can minimise the harmful effects of air pollution on your health.

Avoid outdoor activities, especially in the morning and evening
Delhi's air pollution is a serious issue, with the city topping the list of India's most polluted cities. The air quality tends to be at its worst in the mornings and evenings, so it is imperative that residents limit their outdoor exposure during these times.
The air quality in Delhi is affected by a combination of factors, including vehicular emissions, large-scale constructions, industrial waste, and garbage dumps. In addition, the burning of crops and firecrackers during festivals such as Dussehra and Diwali releases pollutants and dust particles into the air, further deteriorating the air quality. These pollutants can cause serious health issues, particularly for those with heart or lung conditions, the elderly, and children.
To protect yourself from the harmful effects of air pollution, it is best to avoid outdoor activities, especially in the early morning and evening hours. Doctors recommend keeping the doors and windows of your homes closed during these times to prevent the polluted air from entering your living space. If you must go outside, wear a pollution mask with a carbon filter, an exhaust valve, and a filter higher than N95. Ensure that the mask fits perfectly to provide the best protection.
For those who enjoy morning walks or workouts, it is advised to change your routine. Instead of exercising outdoors in the morning or evening, opt for indoor activities or exercise after sunrise when the air quality is comparatively better. You can also consider purchasing an air purifier for your home to minimise the number of pollutants you breathe in.

Use air purifiers to minimise pollutants indoors
Delhi's poor air quality is a well-known issue, with the city topping the list of most polluted cities in India. The air is filled with dangerous pollutants, including particulate matter, gaseous air pollutants, and ground-level ozone. These pollutants can have severe health effects, especially for people with heart or lung conditions, the elderly, children, and pregnant women.
One way to minimise the impact of Delhi's pollution is to use air purifiers indoors. Air purifiers with HEPA and activated carbon filters can effectively reduce indoor air pollution by capturing particles, VOCs, bacteria, and even viruses. This is especially beneficial for those who are more susceptible to the health effects of air pollution, such as people with respiratory conditions, the elderly, and young children.
When choosing an air purifier, look for one with a good-quality filter, such as a HEPA filter, which can remove a high percentage of harmful particles from the air. Place the air purifier in the room where you spend the most time, and ensure that it is properly maintained by regularly cleaning or replacing the filter. Sealing windows can also help keep outdoor pollutants from entering your home.
While air purifiers can significantly improve indoor air quality, they are not a one-time solution. It is essential to replace the filters frequently, especially in highly polluted areas like Delhi. Additionally, combining the use of air purifiers with other measures, such as limiting outdoor activities during high-pollution periods, wearing masks when stepping outdoors, and reducing indoor pollutants, can further help minimise the impact of Delhi's pollution on your health.
By taking these proactive steps, residents of Delhi can better protect themselves from the harmful effects of air pollution and create a healthier living environment, even in the face of the city's ongoing air quality challenges.

Avoid high-intensity exercises that require deep breathing
Delhi's air pollution has been described as "off the charts", exceeding the highest value of the Air Quality Index (AQI) of 500. The World Health Organization (WHO) considers an AQI reading of 5 or below to be healthy, but doctors in India believe that the country's high levels of air pollution necessitate a more relaxed standard. According to Dr Madhu Sudan V, an AQI score of 50 or less indicates healthy air quality, while a score of over 300 is hazardous.
Given the poor air quality in Delhi, it is advisable to avoid high-intensity exercises that require deep breathing, especially outdoors. Running or jogging, for example, can cause shortness of breath, and if the air quality is poor, the reduced oxygen supply can aggravate this condition. Delhi-based coach and founder of Kosmic Fitness, Gagan Arora, advises against exercising outdoors unless it is absolutely necessary. If you must exercise outdoors, check the AQI levels and only train when the levels are well under 200. Even then, reduce the intensity and volume of your workout to protect yourself from pollution.
If you choose to exercise outdoors, it is crucial to wear an N95 mask or a mask with a higher filter. However, it is essential to recognise that even with a mask, working out outdoors can disrupt your breathing patterns and leave you breathless or dizzy. Hence, it is generally recommended to opt for indoor exercises when facing high pollution levels, such as yoga, strength training, pilates, spinning, indoor cycling, or treadmill running.
To maintain your physical health and fitness, consider indoor alternatives to your regular outdoor exercises. For example, instead of jogging outdoors, use a treadmill or try indoor cycling. If you enjoy high-intensity interval training (HIIT), explore indoor options like spinning or indoor HIIT workouts that do not require a mask. By prioritising indoor exercises, you can still maintain your fitness routine while minimising the harmful effects of air pollution.
Additionally, you can incorporate specific breathing exercises into your daily routine to strengthen your lungs and improve your respiratory health. For instance, try the following: stand straight with slightly bent knees, fold your torso over your legs, and hold your opposite elbows to form a square with your arms, allowing your head and neck to hang freely. In this posture, focus on taking deep breaths and relaxing. This practice is an effective way to avoid pollution-related infections, particularly those affecting the sinuses.
