• Heat effect modification by air pollution on cardiovascular and respiratory mortality was investigated across 482 cities.
• Heat effect was seen to be significantly modified by air pollutants PM10, PM2.5, O3, and NO2.
• This study is the most extensive research to date investigating the heat effect modification on cardiovascular and respiratory mortality.
• This is the first-ever study to deeply investigate effect modifications by air pollutants such as PM2.5 and NO2.
