As 90 million people across Europe continue to swelter in a record-breaking summer heatwave, Brits are likely looking for efficient ways to stay cool.‌Yesterday (Wednesday, June 24), the UK saw its hottest June temperatures on record, with Hampshire sweltering at 36.1C and hundreds of schools closing. The Met Office has forecast highs of at least 38C today, with red extreme heat warnings in place.‌Much of the UK’s infrastructure simply isn’t built for such extreme heat, leaving many Brits turning to fans and likely lamenting the lack of air conditioning - but one heating expert says a simple hack could help.‌Adam Chapman, founder of the home-heating resource Heat Geek, highlighted the trick in a 2024 YouTube video, where he ran through 17 tips for keeping homes cooler.He said: "I'm just watering our roof, which is actually tip number two - spray down your roof tiles. Roof tiles absorb heat then radiate it back down into the house. If you can cool off those tiles, you're also cooling down the house."‌It’s worth noting that the hack won't be suitable for everyone, particularly if you can't safely spray your roof or you're under a hosepipe ban (such as in Kent), but it could be another option for people looking to stay cool.Earlier this week, reports emerged sharing other cooling methods.The tips included keeping your blinds, curtains, and shutters closed during the day and opening your windows when it cools in the evenings.‌In terms of the first tip, home experts at Country Living say: "Do this early on in the day, long before temperatures peak. You may also wish to consider using a reflective surface at windows, such as a reflective window film, external foil screens or budget-friendly tin foil, to bounce the heat away."As for the latter, it added: "While you seal everything shut during the day, these are the times to fling open the window (and doors when awake), especially those upstairs, to flush out the hot air and let in the cool air."Article continues belowMeanwhile, the Red Cross suggests focusing on cooling one room. It says: "Keep windows covered and shut and close doors to stop warm air entering."It added: "Try to avoid, or spend as little time in as possible, rooms that will be hard to keep cool, like a kitchen where heat is generated by appliances and cooking devices, or rooms with large windows where the sun is shining."As for fan use, consumer watchdog watchdog Which? suggested not turning it on unless you're in the room, placing your fan by your window if it's cooler outside than in, and placing a bowl or glass of ice under your fan.
