Description
Hongli Wan and colleagues report a 2026 time-series study from Shenzhen, China, on how cold spells and nitrogen dioxide pollution combine to affect out-of-hospital cardiac arrest. The analysis covered 16,769 arrests from 2015 to 2019 in this subtropical megacity. Cold spells and heatwaves were defined by temperature percentiles lasting two to four days.
Cold spells raised arrest risk in step with their severity, while heatwaves showed no clear effect. Cold and nitrogen dioxide together produced more risk than either factor alone. Under the most extreme cold definition, about 28 percent of cases were attributed to the combined exposure. The combined effect was strongest for shockable heart rhythms, which can respond to prompt defibrillation. The authors call for warning systems that track cold and pollution together.
