heatstroke

In cities, medical personnel ran low on cooling supplies, so they resorted to filling body bags meant for cadavers with ice, then zipping unconscious victims of heatstroke inside.

"Previous research has shown depression, anxiety, obesity and heatstroke are more prevalent in urban areas that lack access to shady tree canopy and green open spaces," said Croeser, from RMIT's Centre for Urban Research.

The 3-year-old girl, whose mother was in the car with her, died Friday in what authorities believe to be complications from a heatstroke.

"You have to remind your coworkers to drink a lot of water, so they can stay hydrated and avoid getting heatstroke."

Heatstroke: Once a body temperature reaches 40C or higher, heatstroke can set in.
