Delhi chokes as AQI drops to Very Poor; Essential tips to safeguard your health

While Delhi recently experienced a respite from the heat wave in early October, pollution levels have sharply increased, raising concerns across the city. Over the past several days, the Air Quality Index (AQI) has fluctuated between 250 and 300, placing multiple areas in the "very poor" category. Due to deteriorating air quality, an orange alert has been issued, covering much of the city.

At India Gate, the AQI has dropped to 270, while Anand Vihar has witnessed a significant decline with an AQI reading of 339. This surge in pollution is having a detrimental effect on public health, with dense smog blanketing large parts of the city, contributing to widespread discomfort.

Vulnerable groups at greater risk

Certain groups are more susceptible to the harmful effects of air pollution. These include children under the age of 18, adults over 65, pregnant women, people with chronic heart or lung diseases, diabetes patients, and those who spend prolonged periods outdoors, such as outdoor workers and avid exercisers. Due to their increased vulnerability, these individuals are often the first to experience the impact of elevated ozone and particle pollution and should take necessary precautions to protect their health.

How to stay safe amid poor air quality

Air pollution poses a threat to everyone’s health, so staying informed about the AQI in your area is crucial. The Environmental Protection Agency (EPA) offers real-time AQI data on its AirNow website. AQI levels below 100 are considered satisfactory, but when levels are higher, it's essential to monitor how you feel and take steps to protect yourself.

Here’s what you can do on days when air quality hits orange, red, or worse:

1. Limit Outdoor Time: Reduce the amount of time you spend outside, particularly when the AQI is high. The EPA notes that prolonged and strenuous outdoor activity increases your risk of being affected by poor air quality.
2. Wear a Mask: If you must go outside, wear a well-fitted N95 or KN95 mask, as these offer better protection against fine particles than cloth or dust masks.
3. Maintain Indoor Air Quality: Keep windows and doors closed, run air conditioning on a recirculate setting, and use a portable HEPA air cleaner to ensure the air inside your home remains healthy.
