As India battles one of its harshest summers yet, heatwaves are not just exhausting—they’re dangerous, especially for people living with asthma. With climate change fueling longer and more intense heat spells, asthma patients are facing a new health crisis: breathing has never been harder.
We spoke with Dr. Vikas Pilaniya, Consultant Pulmonologist at Manipal Hospital, Jaipur, to decode the connection between rising temperatures and respiratory health—and to find out how those at risk can protect themselves during extreme weather conditions.
How Heatwaves Are Triggering Severe Asthma Flare-Ups
For people with asthma, a heatwave isn’t just uncomfortable—it can become a serious health emergency. Here’s why:
According to Dr. Pilaniya, extreme heat boosts ground-level ozone, traps dust, smoke, and pollen, and worsens air pollution—all of which irritate the lungs and airways. “The combination of high heat and pollutants creates a perfect storm for asthma symptoms to spiral,” he explains.
Humidity and dehydration, common during summer, also dry out the airways, making them more reactive to allergens and pollution. This can lead to:
- Frequent use of rescue inhalers
- Shortness of breath and tight chest
- Increased fatigue and disrupted sleep
- Severe asthma attacks requiring hospitalization
“Heatwaves magnify respiratory distress and should be taken seriously by anyone with pre-existing lung conditions,” Dr. Pilaniya warns.
Smart Tips to Manage Asthma During a Heatwave
The good news? With the right precautions, you can reduce your risk and breathe easier—even when the temperature soars. Here’s what doctors recommend:
1. Stay Indoors During Peak Heat Hours
Avoid going out between 11 a.m. and 4 p.m. when the sun is at its harshest. Plan activities early in the morning or after sunset.
2. Keep Your Environment Cool
Use air conditioning or fans, and ensure your living space is well-ventilated. A cool, dry environment reduces exposure to allergens and irritants.
3. Hydrate, Hydrate, Hydrate
Drink plenty of water throughout the day. Dehydration makes asthma symptoms worse by drying the mucus in your lungs.
4. Monitor the Air Quality Index (AQI)
Track AQI using apps like SAFAR or AQI India. Poor air quality isn’t just a winter problem—summer pollution is now a major trigger. Stay indoors on days when AQI is poor.
5. Eat Light and Nutritious Meals
Spicy, oily food can make your body work harder to digest, adding more stress. Go for cooling fruits, veggies, and non-acidic foods that support lung health.
When to Seek Medical Help
If you’re experiencing worsening symptoms like chest tightness, wheezing, or prolonged shortness of breath, don’t delay. Contact your doctor or visit a hospital immediately. A severe asthma attack during a heatwave can escalate quickly and may require emergency care.
Why This Matters More in 2025 Than Ever Before
Climate change is no longer a distant concern—it’s here, and it’s personal. With global temperatures hitting record highs this year, asthma patients are among the most vulnerable.
But knowledge is power. With guidance from experts like Dr. Pilaniya and a few simple adjustments in your routine, you can safeguard your health and enjoy summer safely.
