Can humans survive a future of extreme heat?

Can the human body survive climate change? That’s the burning question in this episode of Totally Cooked. With the world already experiencing more frequent and intense heatwaves, we sit down with Professor Ollie Jay from the University of Sydney to explore how our bodies respond to extreme heat, and what happens when they can’t keep up.

Ollie walks your co-hosts Professor Sarah Perkins-Kirkpatrick and Iain Strachan through the science of sweating, hydration, and heat stress, and explains the critical tipping points between heat exhaustion and deadly heatstroke. We discuss who’s most at risk, why heat is often overlooked as a killer, and what governments, communities and individuals can do to stay safe in a hotter world. We also find out what it’s like to sit in a room set to 54°C, and why your fan might not be helping as much as you think.

Plus, it’s quiz time: from Death Valley to the Ashes, the FIFA World Cup to the Sahara, we put Sarah and Ollie to the test with a scorcher of a quiz on record-breaking heat. If you’ve ever wondered whether climate change is cooking us alive (and how long we can keep turning up the thermostat) this episode has the answers.

Iain records Totally Cooked on the lands of the Bunurong People of the Kulin Nation. Sarah records Totally Cooked on the lands of the Ngunnawal and Ngambri people. We pay our respects to Elders past, present and emerging and recognise their unique and continuing connection to the land, skies, waters, plants and animals.
