With homes in the UK acting like brick ovens and soaring energy bills leaving many in the US hesitant to blast the AC, the summer heatwaves are set to ruin your sleep. You need a way to cool down before bed so you don't spend the next few months sweaty, sticky and sleep deprived.

Your internal body clock relies several signals to fall asleep and one of them is temperature — your core needs to drop around 2°F / 1°C for you to drift off. But when your room is too warm, your body is unable to disperse heat efficiently. This leads to tossing and turning, which in turn causes cortisol levels to spike, leaving you vulnerable to 3 a.m. wake ups.
