We’re all aware of the physical risks associated with extreme heat, like dehydration and fainting for example. But a number of scientific studies have shown that heatwaves also have a major impact on people’s mental health.

It’s important to highlight that the difference can be experienced by anyone, not just those with existing psychiatric conditions. But one thing is for sure: the vast majority of us are more anxious when temperatures are high. And it makes sense that we get more irritable when you consider how our bodies work. Heat causes our heart rate, pulse, blood pressure and cortisol levels to all increase. Meanwhile, it deregulates so-called happy hormones serotonin and dopamine.
