Red Cross shares sock-in-fridge trick to beat heatwave sleeplessness

With temperatures across the UK set to hit 30C this weekend, the British Red Cross has urged people to aim for seven to nine hours of sleep a night – and even suggested putting socks in the fridge to cool down before bed. The charity acknowledged what many already know: “it can be difficult to sleep in a heatwave”. But fewer people realise that the amount of sleep you get can influence how your body copes with the heat. “If it's too hot or too cold, your internal body temperature may be affected, disrupting your ability to fall asleep and stay asleep,” the Red Cross explained. “This is important as getting good-quality sleep during a heatwave helps your body recover, stay cool, and maintain overall physical and mental health.” For vulnerable groups, sufficient rest is even more vital: it supports the immune system, boosts energy levels, promotes heart health, and helps the body manage the additional strain caused by extreme heat. According to the NHS, an adult usually needs between seven to nine hours of sleep a night, though this varies by age, health and personal circumstances. Teenagers, children and babies need more. Even one night of poor sleep can negatively affect your health, the Red Cross noted, while longer-term problems can affect relationships, social life and daily tasks. The charity also highlighted a simple hack: during the day, place a pair of socks in the fridge, then put them on before bed. Cooling your feet can help lower overall body temperature, creating a refreshing cooling sensation as you settle in for the night. Anyone who regularly struggles to get at least seven hours of sleep – especially if it is affecting daily life – is advised to speak to their GP.
