Exeter paramedics Connor Gilronan and Charlotte Sherston give him medication and oxygen, and remind him to stay cool and hydrated.

"People die in heatwaves.

Not because they were out running around or taking risks, but because they're elderly and don't realise how at risk they are," he says.

Those with chronic conditions are also at elevated risk, as symptoms from existing conditions are intensified. These health risks pile pressure on an already stretched service. In the June heatwave the South Western Ambulance services received a record number of emergency 999 calls: about 3,000 incidents a day are typically reported in the peak of winter, a number rising to over 4,000 in the heatwave.

"Our number of calls tracks the temperature - it's a very correlated trend," says Dr John Martin, chief executive of the South West Ambulance Service. The trust covers 10,000 square miles – from Cornwall to Swindon – and expects further pressure this week, not only from heat‑related illness but also from water‑related injuries and drownings, which spike during hot weather. Further north, the South Western Ambulance Service (SWASFT) in North Somerset said it had dealt with its busiest ever day in June, "completely beyond anything it has ever experienced".
