If there’s anything more uncomfortable than enduring a heatwave in Britain, it’s sleeping through one.
But hot nights are only going to get more common if the climate crisis continues its long march. While Britons are already accustomed to poor sleep – with the average adult getting just three days a week of good kip, according to the Mental Health Foundation – heat doesn’t help. Dr Allie Hare, consultant in sleep medicine and co-president of the British Sleep Society, says: “Being too hot during sleep can significantly reduce sleep quality and duration. In particular, it can reduce slow wave (deep) sleep, the stage of sleep that helps us awaken feeling rested.”
