‘Woefully unprepared’: extreme heat will double US hospitalizations by 2040, study finds

Sharp rise in hospital visits will in turn drive up annual healthcare costs for heat-related conditions to over $1bn

People in the US are poised to endure another summer of unusually ferocious heat and there will be little respite in the years ahead, with a new study finding that the coming 15 years could see a doubling in hospitalizations due to heat-related illnesses.

The number of annual heat-related emergency department visits or hospitalizations across the US are set to rise from about 109,000 cases a year to as many as 237,000 cases by 2040, the new research has estimated.
