Air pollution results in a significant increase in the concentration of Particulate Matter 2.5 (PM2.5), which are tiny particles in the air. When these tiny particles, that are 1/30th the size of human hair, are inhaled, they travel all the way to the base of the lungs and enter the blood stream, resulting in widespread damage to all the major organs in the body.

"There is robust evidence to suggest that the rate of people getting infected with COVID-19 is much higher in areas where there are high levels of air pollution. There is a strong correlation between air pollution and severity of COVID-19 infection resulting in increase in mortality. Those who have recovered from COVID-19 infection are also significantly susceptible to effects of the pollution," Dr P Raghu Ram, President, The Association of Surgeons of India, tells DoctorNDTV.

  • Wearing a properly fitted mask and social distancing is a must when out in the community.
  • Practicing hand hygeine is very important.
  • Avoid exercising outdoors as increase in inhalation of polluted air results in significant damage to the respiratory system. Adjust to the new normal and increase indoor physical activity.
  • Indoor air pollution must be kept in control. Avoid incense sticks and mosquito repellent sprays.
  • Say no to fire crackers as they only worsen air quality.
  • Do simple yogic practices like Simha Kriya, whic can significantly enhance one's immunity. You can also do Pranayama (Breathing exercises) and mediation, which can calm the mind and body.
