When temperatures soar, so do our levels of anger, stress and anxiety. Research carried out by the Brain and Behaviour Research Foundation found that this is because your heart rate and blood pressure rise as your body tries to cool itself down.
Combine that with the anxiousness that results from dehydration, and you can quickly become extremely stressed during a heatwave without even knowing why. Luckily, there are a few ways of fighting back. Cold green tea is a great de-stresser in the heat, as it contains the amino acid theanine, which reduces anxiety.
Likewise, a sneaky bit of dark chocolate will calm you down when you’re too hot. Research published in the Journal of Proteome Research showed that people who eat dark chocolate on average have lower levels of the stress inducing hormone cortisol.

Cut back on alcohol
There’s nothing quite like a refreshing beer in the sunshine, but if you want to stay heatwave healthy you’ll need to limit how much alcohol you drink. In fact, according to a study at Loughborough University, it might even be best to cut back on alcohol all together when temperatures rise.
The study found that even drinking a small amount of weak beer causes diuretic effects that lead to dehydration. Most of the time this isn’t a problem – a heatwave is a different story.
