World Asthma Day is observed annually on the first Tuesday of May, driven by the Global Initiative for Asthma (GINA) to promote awareness and improve care. The 2025 theme, “Make inhaled treatments accessible for all,” highlights the urgent need for equal access to essential medication.
Asthma, a chronic lung condition impacting over 262 million people globally, poses a growing health challenge. India bears a disproportionate share hosting 13% of global asthma cases (34.3 million) according to the 2019 Global Burden of Disease report.
Pollution and Climate Deepen India’s Asthma Woes
While genetics can increase the likelihood of developing asthma, environmental triggers such as pollution, climate shifts, and poor lifestyle habits are intensifying the problem. For those with asthma, airways become inflamed and overly sensitive, making them vulnerable to irritants like dust, smog, and smoke. This leads to symptoms such as coughing, wheezing, and shortness of breath, with severe cases requiring hospitalisation.
India’s outdoor air pollution often surpassing safe limits and indoor hazards like cooking smoke, incense, mold, and dust mites, greatly amplify these risks. The World Health Organization estimates that 9 out of 10 Indians breathe polluted air daily.
Rapid climate shifts cold waves, heat spikes, and high humidity further aggravate asthma. Cold, dry air can constrict airways, while hot, humid conditions raise airborne allergens. Even thunderstorms can trigger sudden asthma attacks due to airborne pollen particles, a condition known as “thunderstorm asthma.”
Urbanization contributes as well, with rising dust from construction, road traffic, and sedentary lifestyles increasing vulnerability. Poor diet, physical inactivity, and high tobacco use (around 27% of the population) also add to the burden.
Managing Asthma in India: Steps and Tools
As India grapples with worsening air quality, managing asthma has become more urgent. Key strategies include:
- Consulting doctors to identify personal triggers and develop an action plan.
- Using inhalers both daily control and rescue variants effectively, with medical guidance.
- Minimizing outdoor activity during high-pollution periods, staying hydrated, wearing masks, and avoiding busy roads for exercise.
Situation of Asthma in India
India’s asthma situation is especially concerning. Although not the country with the highest asthma prevalence, it records 46% of all global asthma-related deaths, according to the 2021 Global Burden of Disease report. A 2024 study published by the NIH attributes this high mortality to underdiagnosis, poor disease control, and lack of access to effective medication. India’s asthma mortality rate is reportedly three times the global average, and its impact in terms of disability-adjusted life years (DALYs) is more than double the global figure.
Embracing Precision Medicine and Digital Tools
India is shifting from generic asthma care to more personalised and technology-driven treatment. Tools like FeNO testing (which measures inflammation), impulse oscillometry, high-resolution CT scans, and biologic therapies such as anti-IgE and anti-IL5 antibodies (mepolizumab, benralizumab, reslizumab) are transforming asthma management, especially for patients with severe symptoms.
“These treatments significantly reduce flare-ups and dependence on steroids,” says Dr. Gyanendra Agrawal of Max Super Speciality Hospital, Noida. However, the high costs and limited insurance coverage make biologics unaffordable for many, particularly in smaller towns and rural areas. Treatment costs can range from ₹18,737 to ₹1,18,303 annually, depending on severity and hospital visits.
Smart Inhalers and Apps: Aiding Long-Term Management
Technological advancements are improving adherence to asthma treatment. Smart inhalers equipped with Bluetooth track usage and send real-time data to physicians. Dry Powder Inhalers (DPIs) offer better drug delivery, while mobile apps allow users to log symptoms, monitor lung function, and get medication reminders.
“This tech empowers both patients and doctors to tailor treatments and respond to real-world data,” notes Dr. Agrawal.
Bridging the Urban-Rural Gap
Despite progress in metros, many in tier 2, tier 3 cities, and rural areas still lack access to modern asthma care. While basic inhalers are now more widely available, sophisticated biologics and diagnostics are limited to urban centers.
Efforts are underway to improve reach. Telepulmonology, mobile clinics, and public health drug programs are expanding access in underserved regions.
As India marks World Asthma Day, the focus is not just on awareness, but on action ensuring that everyone, regardless of location or income, can breathe easier.
