When it gets hot, we all get a bit stroppy: think 'shouting at people on the internet' stroppy. But that's only the tip of the (melting) iceberg. Too much heat can trigger or make worse a range of mental health conditions. And what does climate change bring? More heat. So what are the mental health implications of rising global temperatures?

Joining Dave this episode is Dr Alessandro Massazza (X / LinkedIn) - Policy Advisor for United for Global Mental Health. Ale tells Dave all about what the science has to say about the very many ways getting too hot can fry your state of mind - and why it's time to give mental health a proper seat at the climate table.
