Heatwave anxiety can make you feel 'incredibly helpless' - here's how to manage it

Watts is not alone. A 2022 study from the University of Bath estimates that about 4.6% of people in the UK have climate anxiety, which is recognised as a form of mental distress by professional bodies and the NHS. Young people and women are among the groups most at risk, according to a study published in 2025.

"Anticipatory anxiety", related to heatwaves in particular, has become more common, say psychologists Dr Caroline Hickman from the University of Bath and Dr Emma Lawrance from the University of Oxford.

"Once people have been through a traumatic event like a flood or a heatwave, they anticipate the next one," Hickman, who offers therapy to individuals experiencing climate anxiety, told the BBC.

In the UK, "now we're getting the repeat, repeat, repeat [heatwaves]. It triggers that sense that 'I can't be safe in the world, and the world can't be trusted'," she added.

In June's heatwave, Hickman said she "had people saying they're going to kill themselves, I've had people saying they're going to terminate pregnancies, I've had people saying that they want to sell their houses and move somewhere cooler".

Watts said that her video "clearly struck a chord with people" - including therapists posting comments about coping mechanisms - and that she wanted to help others deal with climate anxiety.

"It can go one of two ways. You can either just fall into doomism and think, 'What is the point?'" she said.

"Or you can try to do something. I sign petitions during a heatwave; I organise climate community events; I run a free children's clothes swap shop. During the last heatwave, I finally became vegetarian, because then I can tell my kids at least I tried."
