After what seems like the longest winter ever (was anyone else still wearing their coat in May?), summer has finally arrived, with temperatures soaring over the past month.

And while we are big fans of summer, there’s one aspect of the warmer weather that isn’t much fun: how sleepy and lethargic it makes us feel.

When the mercury rises, it can be tough to motivate ourselves to do much at all. Exercise regimes fall by the wayside (who wants to do a HIIT in a heatwave?) and by the end of a workday, all we’re good for is a sundowner and snacks with mates.

Feeling lethargic and lacklustre? The weather could be to blame
