What Does Extreme Heat Do to the Body?

Watch more of this series: https://to.pbs.org/4wkQIAG The climate crisis isn't a distant threat — it's already here, and it's deadly. But keeping people cool is surprisingly complicated. In Sydney, Australia, physiologist Ollie Jay is tackling the problem by studying how the human body responds to extreme heat. The ultimate goal is to create low-cost cooling strategies for people without access to air conditioning — those most at risk from extreme heat. Science journalist Miles O'Brien puts himself in the hot seat — literally — to find out what it feels like when the body's cooling system starts to fail.
