For how we live.
A Utah case-crossover analysis found heat stress and pollution interacting synergistically in the warm season. A Louisiana crisis-hotline study traced hot nights to sleep disruption and unmet basic needs.
A pan-tropical analysis links deforestation-driven local warming to about 28,000 heat-related deaths a year, with Southeast Asia carrying the highest rate.
A 15-city study found a pooled relative risk of exactly 1.00 for heat warnings. Adjusting for green space, population and density turned it into 0.85. Both numbers are in the same paper.
About 1,009 deaths a year were attributable to heatwaves in 2016-2019. Queensland and New South Wales carried rates more than three times Western Australia's.
Twenty adults sat for three hours at 39 °C with and without a fan, hydrated and not. Dehydrated, the fan raised heart rate and stopped feeling better, while sweat losses rose either way.
