Temperatures above 50 degrees Celsius have been recorded in China and the US and the UN chief says the era of global warming has ended and “the era of global boiling has arrived”.

When it’s extremely hot, there are more hospital admissions and more deaths. But one thing that isn’t talked about as much is how the heat affects your mental health. So, in this episode we’re asking: What in the World happens to your mental health in extreme heat?

Hannah Gelbart is joined by BBC reporters Kelly Ng and Sofia Bettiza, and also Dr Dominic Canova from New York City.

Plus, the BBC’s Mimi Fawaz explains how Moroccan defender Nouhaila Benzina has made history by becoming the first football player to wear a hijab at a World Cup.
