A peer-reviewed study reports that heatwaves in India coincide with elevated ground-level ozone, which is linked to increased cardiac deaths. The study finds that surface ozone levels reach about 85–110 μg/m³ in northern India during heatwaves and that concentrations exceed the World Health Organization (WHO) guideline threshold of 70 μg/m³ across every region of the country. The research also compares mortality during heatwave periods with preceding days. For 2024, it estimates that there are about 830 more reported deaths during the heatwave than on the days immediately beforehand, attributing the increase to the combined effects of heat exposure and ozone pollution. By focusing on the interaction between extreme temperatures and air quality, the study highlights a health risk that can worsen during seasonal heat events. The findings are based on the reported pattern of ozone rising during heatwaves and the corresponding change in cardiac-related mortality statistics during those periods.

- A peer-reviewed study examines the combined effects of heatwaves and ground-level ozone on cardiac deaths in India.
- During heatwaves, surface ozone reaches about 85–110 μg/m³ in northern India.
- Ground-level ozone exceeds the WHO guideline of 70 μg/m³ in every region of India during heatwaves.
- The study reports that in 2024 there are roughly 830 more reported deaths during heatwave days than in the preceding days.
- The study links higher cardiac mortality to exposure to both heat and elevated ozone.
