Tragedy of Madrid street sweeper highlights how heatwaves kill

Three hours into his shift as a street sweeper in Madrid on a summer afternoon when temperatures went above 40 degrees Celsius (104 Fahrenheit), Jose Antonio Gonzalez fainted from heatstroke. He died the next day in hospital.

With the Spanish capital on heatwave alert, the 60-year-old had set out for work that day in July 2022 with two two-litre bottles of water and a spray bottle to cool off.
