Yeah.

[birds chirping] My name is Andrea Micheli.

I'm a professor of early intervention in mental health at King's College London.

I'm a clinical psychologist, and I've worked in the NHS for several years, and one thing I did notice is that when people move from the countryside to London, where I worked, often they will struggle with their mental health.

And this is something that is reflected in the literature.

People who live in cities are more vulnerable to developing mental health issues.

So I wanted to understand why.

It feels like one symphony of so many different things in, in unity.

And, and, you know, with the heat waves in London, I'm sure you can attest to what it's like living in an urban setting.

Yeah, absolutely.

And what's interesting is if you ask people, um, "Do you, do you struggle w-with your mental health during a, a heat wave?" Um, the vast majority of people will say, "No.

Actually, I quite like the heat." Uh, particularly in places like the UK, hot temperatures are still considered, uh, you know, a, a good thing.

Um, but then if you ask them, "How do you sleep during a heat wave?" They would say, "Oh, it's terrible.

I really struggle.

I can't sleep." "And how is your energy during a heat wave?" They would say, "I feel exhausted.

Like maybe a library or, uh, public spaces that have air conditioning, something like that maybe?
