The increasing frequency of extreme heat events is fueling anxiety and distress, a phenomenon psychologists are identifying as a significant mental health concern. This 'climate anxiety,' or 'anticipatory anxiety' specifically linked to heatwaves, is leading some individuals to feel a profound sense of helplessness.
Dr. Caroline Hickman, a psychologist from the University of Bath who offers therapy for climate anxiety, noted that repetitive heatwaves trigger a sense of insecurity. "Once people have been through a traumatic event like a flood or a heatwave, they anticipate the next one," Hickman stated. "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.'"
This heightened anxiety can manifest in severe reactions. During a recent heatwave, Hickman reported hearing from individuals considering drastic measures such as ending their lives, terminating pregnancies, or selling their homes to relocate to cooler climates.
A 2022 study from the University of Bath estimated that approximately 4.6% of the UK population experiences climate anxiety. Research published in 2025 indicated that young people and women are particularly vulnerable to this form of mental distress, which is recognized by professional bodies and the National Health Service.
Some individuals are channeling their anxiety into action. One person shared that during a heatwave, they signed petitions, organized community climate events, and ran a children's clothes swap shop. They also reported becoming vegetarian, stating, "I can tell my kids at least I tried." This approach contrasts with succumbing to "doomism," the feeling that individual actions are futile.
Psychologists like Dr. Emma Lawrance from the University of Oxford are also observing the rise in heatwave-related anxiety. The emotional toll of extreme heat is significant, prompting a need for coping mechanisms and support for those affected. The experience can lead to a feeling of being "incredibly helpless," highlighting the psychological impact of a changing climate.
