‘Scary’ heatwave side effect that some people don’t even think about as temperatures soar across the UK

With temperatures soaring and the UK heading towards one of its hottest Junes on record, many people are understandably focused on the physical effects of the heat.

But there’s another side effect that often gets overlooked. Specifically, the impact a heatwave can have on your mental health.

Across social media, people have been opening up about how the extreme temperatures are affecting them emotionally, with Reddit users describing feeling 'really scared', 'extremely anxious', 'terrified', and even like a 'caged animal' during the heatwave.

Some have also said the hot weather has triggered 'panic attacks'.

According to BACP registered counsellor L.J Jones, these reactions are more common than many people realise.

Jones told the Metro: "A heatwave can have a significant impact on mental health.

"Many people report feeling more anxious, irritable, overwhelmed, or emotionally and physically exhausted during periods of intense heat.

"For individuals who already live with anxiety disorders, depression, panic symptoms, health anxiety, or sensory sensitivities, hot weather can amplify existing difficulties.

"It’s also common for people to describe feeling trapped or confined, particularly if they are unable to comfortably leave their home, exercise, socialise, or engage in the activities that usually help them manage their well-being."

But why does hot weather affect us so much?

Jones explains that intense heat places extra stress on the body.

It can increase your heart rate, disrupt sleep, cause dehydration and trigger physical sensations that can feel similar to anxiety.

When you're already feeling exhausted and uncomfortable, it becomes much harder to cope emotionally.

There’s also the feeling of having very little control as many people worry about their health, vulnerable relatives, pets, rising temperatures and the possibility of heatwaves becoming more frequent.

And in the UK, where air conditioning is far from standard, escaping the heat isn't always easy.

"When people feel they have no effective way to escape the heat, it’s understandable that they may begin to feel trapped in their own homes," Jones continues.

"That sense of being unable to get comfortable, cool down or carry on with normal routines can have a significant impact on mood and emotional well-being.

"The psychological strain isn’t just about the temperature itself – it’s also about feeling ill-equipped to manage it."

If you're struggling with anxiety during a heatwave, Jones recommends focusing on what you can control: staying hydrated, keeping your home cool, eating regular meals and getting enough sleep can all make a difference.

She also encourages people to keep up the activities that support their mental health, even if they need to be adapted for the weather.

"People should also try to continue activities that support their mental health, even if they need to adapt them. For example, exercising early in the morning, connecting with friends indoors, or spending time in air-conditioned public spaces," she added.

"It is also worth noting that this time will pass, and society will even become better-equipped for the future."
