What is worse than extreme heat? Extreme heat plus air pollution

The Hindu  

Heat waves and air pollution from wildfire smoke and other sources are each problematic for human health, particularly for vulnerable populations such as older adults. The risk of death on those extra-hot and polluted days was about three times greater than the effect of either high heat or high air pollution alone. Why risks are higher when both hit at once There are several ways the combined exposure to extreme heat and particulate air pollution can harm human health. Our research also showed that the effects of particulate air pollution and heat extremes were larger when high nighttime temperature and pollution occurred together. Older adults may be more susceptible to effects of extreme heat and air pollution exposure, in part because this stress comes on top of age-related chronic health conditions like heart disease, high blood pressure, diabetes or chronic lung disease.
