Most people associate heat illness with deserts, tropical climates, or overseas holidays. 

 

Not the UK. 

 

Yet every year, people become seriously unwell during periods of hot weather. Walkers, runners, horse riders, outdoor workers, instructors, festival-goers, and even spectators can all be affected. 

 

The problem is that heat illness rarely starts as an emergency. 

 

 

Until it isn't. 

 

You’re an hour into a coastal hike. It’s roasting. One of your group sits down suddenly, looking pale, sweaty, and just not quite right. “I’m fine,” they say. But are they? 

 

As an EMT, I’ve treated more than a few heat-related emergencies — on city streets, at music festivals, and the uplands of the UK where help is hours away. The key to managing heat illness is catching it early, acting fast, and knowing when ‘just hot’ becomes dangerous.
