Diwali is one of the most cherished Indian festivals. There is a spirit of joy and harmony in the air. Homes are lit with diyas and various glittering lights. Doorsteps are decorated with rangolis. Kitchens are filled with varieties of sweets. The roads come alive with the sounds of crackers and laughter echoes as families gather to celebrate. The whole ambience brings joy, togetherness, and positivity. 

But do you know, it also brings a serious concern with it, that is the air pollution. Every year, especially in North Indian cities, air quality drops dramatically around Diwali. The main culprit? Firecrackers. They’re fun, loud, and beautiful — but they release a toxic mix of gases and fine particles into the air.. Many cities cross AQI 400 that carries serious health risks, especially for children, elderly, and people with respiratory issues.

The Supreme Court of India has reminded us time and again: while our right to celebrate is important, it cannot come at the cost of our right to clean air.

What’s Actually in That Smoke?

Every year during Diwali time, tonnes of firecrackers are sold. These crackers release a cocktail of harmful gases such as sulphur dioxide (SO₂), nitrogen oxides (NOx), carbon monoxide (CO), and fine particulate matter (PM2.5 and PM10) that can enter the lungs and even the bloodstream, causing various health issues. 

Apart from this there is a surge in the use of vehicles as people travel to meet their family and friends. This also contributes to air pollution.

Effects of Diwali Air Pollution on Health:

Though anyone exposed to the Diwali pollution can develop health hazards, they are most pronounced in vulnerable groups— children, the elderly, and those with pre-existing respiratory or cardiac conditions. The symptoms could last short term or long term in many. Some of them are:

  • Respiratory Issues: The emission of pollutants such as PM2.5, PM10, sulphur dioxide, and nitrogen dioxide cause irritation of airways and some people experience symptoms like coughing, wheezing, breathlessness, and chest tightness. Bronchitis and asthma attacks become more frequent and severe. 
  • Aggravation of Already Existing Chronic Diseases: People suffering from Chronic Obstructive Pulmonary Disease (COPD), asthma, or heart disease may experience a relapse or aggravation of symptoms. Post Diwali there is a surge in hospital visits of people with chronic respiratory conditions. 
  • Eye Irritation: Toxic gases from the crackers may cause burning, watering and irritation of eyes. Some people may experience temporary blurring of vision. 
  • Skin Allergies: The Diwali pollution has heavy metals and chemical residues that can cause skin allergies. People may experience itchiness, rashes and eczema flare ups. Children with sensitive skin are more prone to develop this. 
  • Mental Health Issues: The loud noise from firecrackers can lead to sleep disturbances, anxiety, irritability, and increased stress levels, especially among infants, elderly people, and pets. For individuals with PTSD or mental health issues, the sudden loud sounds can be particularly distressing.

What Can You Do About This:

  • Minimize the use of firecrackers and opt for green crackers that are more echo-friendly.
  • Try to stay indoors during peak pollution hours if you have an already existing health condition that can get aggravated due to the polluted smoke.
  • Keep the windows closed as much as possible and install an air purifier.
  • Wear anti pollution masks if you have to travel outside. 
  • Make sure to have inhalers, nebulizers, or prescribed medications stocked at home if you already suffer from asthma or other chronic respiratory issues.
  • Consume fruits and vegetables rich in Vitamin C, E, and omega-3 fatty acids in your diet to strengthen your immune system.
  • Visit a doctor if you experience severe coughing, breathlessness, chest pain, wheezing, eye irritation, or worsening of chronic health conditions.

Conclusion:

Diwali is a time to celebrate, but the pollution can make this joy short lived. Let’s celebrate the true spirit of Diwali with lights, love, and togetherness—not crackers. Choose joy over noise, and health over harm, for a brighter, cleaner, and safer festival.
