Heatwaves and ozone together increase India’s cardiac deaths: study
A new study indicates that heatwaves exacerbate surface ozone levels in India, contributing to thousands of deaths from heart and lung diseases. The research highlights the indirect health risks posed by climate-related pollution.
Why it matters
Understanding the link between heatwaves and air quality is essential for public health policy and climate adaptation strategies.
While surface ozone — a pollutant harmful to the heart and lungs — already exceeds safe limits across much of India in the hot pre-monsoon months, a new study finds that heatwaves push it to still higher levels , thus adding several hundred deaths to a far larger toll that the study links to ozone across the season.
