New Delhi: Diwali is almost here, and everyone is busy planning parties, shopping for gifts and preparing for celebrations. But if you’ve ever experienced
a migraine or unexplained heaviness in your head after spending time outdoors during Diwali, firecracker smoke could be one of the reasons.
We usually talk about how air pollution affects our lungs, but did you know that polluted air can also affect your neurological health? The tiny particles released by firecrackers, along with strong chemical smells and gases, may trigger headaches or make existing migraines worse.
However, not every headache this Diwali is because of pollution. Late-night celebrations, poor sleep, dehydration and stress can also play a role. So, how do you know whether your headache is linked to firecracker smoke? And when should you actually be worried?
Can Diwali air pollution cause headaches?
Speaking exclusively to News9 Digital, Dr Manav Manchanda, Director and Head of Respiratory, Critical Care and Sleep Medicine at the Asian Institute of Medical Sciences, explained how festive pollution may affect the nervous system and what people can do to protect themselves.
Most people associate pollution with coughing, breathing difficulties and burning eyes. However, its effects may go beyond the respiratory system.
Dr Manchanda explained that headaches can be among the symptoms people experience when air quality deteriorates. “As a doctor, I often remind people that air pollution does not just affect our lungs. It can also impact our neurological health, and headaches are one of the symptoms people may experience during periods of poor air quality, particularly around Diwali,” he said.
Dr Manchanda further explained, “Firecracker smoke contains fine particulate matter, including PM2.5, along with gases and chemical irritants. When we inhale these pollutants, they can trigger inflammation and oxidative stress in the body. Fine particles may also contribute to inflammatory responses that affect the nervous system. For someone who is already prone to migraines, exposure to polluted air, strong chemical smells, and smoke can act as a trigger.”
It’s not just pollution: Your Diwali routine could be a problem
Between late-night get-togethers, endless preparations, bright lights and hectic schedules, sleep and water can easily fall down the priority list. And these changes may contribute to headaches, even without heavy exposure to firecracker smoke.
Dr Manchanda explained, “I would also like to point out that headaches during this period may not be caused by pollution alone. All of these can contribute to it, especially during the festive season: poor sleep, dehydration, stress, exposure to bright lights and changes to routine.”
Migraine or regular headache? Know the warning signs
Migraines can also come with symptoms beyond head pain. Dr Manchanda explained, “People who experience migraines may notice a throbbing headache, sensitivity to light and sound, nausea or worsening pain with physical activity. Others may experience a dull headache, heaviness in the head, eye irritation or dizziness.”
How to save yourself from Diwali pollution headaches
Dr Manchanda advised, “My advice is to avoid prolonged outdoor exposure when pollution levels are high, especially near areas where firecrackers are being burst. Keep windows closed during periods of heavy smoke, use an air purifier indoors if available and stay well hydrated.”
In addition to reducing smoke exposure, getting enough sleep and staying hydrated may also help limit other common headache triggers.
Those with a history of migraines should also be aware of their usual triggers and not assume pollution is the only cause of their symptoms. Dr Manchanda said, “If you are someone who regularly experiences migraines, continue your prescribed treatment and avoid known triggers as much as possible.”
When is a headache a medical emergency?
Dr Manchanda warned, “I would also caution people against dismissing a severe or unusual headache as simply pollution-related. A sudden, extremely intense headache, one accompanied by weakness, confusion, vision changes or difficulty speaking, requires immediate medical attention.”
As Dr Manchanda added, “The important thing to understand is that pollution can be an additional trigger for headaches, particularly in vulnerable individuals, and reducing exposure is an important part of protecting our health.”
