National mortality burden attributable to the unprecedented heatwave in 2022 in China

RESEARCH | Updated：2026-01-29

- National mortality burden attributable to the unprecedented heatwave in 2022 in China
- “In 2022, China faced an unprecedented heatwave, significantly impacting public health. A study analyzed heatwave-related mortality in 364 Chinese counties from 2006 to 2017 and assessed the mortality burden for 2000-2022 in 368 cities. The results showed that heatwave frequency and intensity have increased over the past two decades, with 2022's heatwave-related deaths in China reaching 62,961, much higher than the annual average of 35,987 from 2000 to 2021. The study highlights the urgent need for comprehensive heat adaptation plans amidst rapid aging and global warming.”
