Delhi AQI: The drapes of smog over Delhi-NCR have once again turned the region into a gas chamber, as the Air Quality Index (AQI) has crossed into the ‘severe’ category, hitting the 400 mark in several parts of the city, including Bawana, Rohini, Mundka, and Anand Vihar. The thick fog that has blanketed the Capital is causing health concerns, particularly for patients with heart and lung ailments.
On Sunday morning, the Central Pollution Control Board (CPCB) reported that the average AQI across Delhi was between 395 and 420, which may incite authorities to impose GRAP Stage III restrictions again if the situation does not improve.
Expert Concerned for Heart Patients
Dr Randeep Guleria, a former director of AIIMS, expressed concern that fine particulate matter (PM2.5i) can penetrate deep into the lungs and into the bloodstream, leading to inflammation, blood clots, and loss of life from a heart attack. “This psychic exposure to the toxic air can be dangerous for those with pre-existing heart ailments,” he said.
Cardiologists are prompting elderly and people with hypertension or coronary artery disease to avoid early morning walks, keep doors and windows closed, and use air purifiers at home.
What Causes Delhi’s Air Pollution to Be So Disastrous?
- There are multiple causes for the current pollution spike.
- Air pollution from stubble burning in Punjab and Haryana continues despite the government’s admonishments and stricter monitoring.
- Motor vehicle emissions and dust from construction projects add an even heavier additional particulate load.
- Low wind speeds and falling temperatures have trapped the pollutants close to the ground, resulting in a thick layer of smog.
- Delhi authorities have advised their citizens to rely on public transport, cut down on travel, and wear N95 masks if they must be outside.
Recommendations for Heart Patients on Poor Air Quality Days
Avoid Outdoor Physical Activity during Peak Pollution Hours (6:00 am to 10:00 am & 5:00 pm to 9:00 pm)
Pollution levels are likely to be higher during these times. Heart disease sufferers should choose to limit their time spent outside and conduct all physical activity indoors.
Try keeping the Air Purifiers and Humidifiers running
Keep your air purifiers running, particularly in your bedrooms. A humidifier will also work to assist in alleviating dry throat discomfort associated with dry smog.
Hydrate and Eat Heart-Healthy Foods
Foods rich in antioxidants, such as amla, oranges, spinach, and walnuts, can help limit the oxidative stress against toxins in the air.
Monitor Blood Pressure and Oxygen Levels Often
Kids and adults with cardiovascular issues should have their vitals checked at least once daily, and consult your doctor immediately if you experience any chest discomfort, fatigue, or shortness of breath.
Do Not Exercise Outside
Jogging or biking through smog could do far more harm than good; switch to smithing indoors.
GRAP Stage 3 in Sight: Are We Heading for Another Shutdown in Delhi?
With air quality hovering above the safety threshold again, the Commission for Air Quality Management (CAQM) may soon impose GRAP Stage III — banning construction activities, limiting diesel vehicles, and activating ‘work from home’ directions for government and private offices.
Schools may also switch back to online classes if the situation persists. Although officials have indicated there will be stricter action, officials first want to see the next weather update.
The Broader Implications
Delhi’s air pollution crisis is far beyond an environmental crisis; it’s a public health crisis. While short-term emergency actions could provide “safety nets,’ experts are stressing the need for long-term policy response to reduce vehicular emissions, support a shift to electric active travel and improve energy and heat source technologies.
Until then, Delhites, and especially individuals with heart problems, will have to take health safety interventions and mitigations to ensure they are reducing exposure.
