The Met Office has announced that a third heatwave is set to sweep across much of the UK in July, with southern parts expected to reach 34C to 35C. While not anticipated to match the sweltering temperatures of the June heatwave, many people may still turn to potentially unsafe hacks and tricks in an attempt to stay cool.
Security Risk: Leaving Windows Open Overnight
Numerous reports have advised keeping windows shut during the hottest part of the day to prevent heat from entering the home. However, some have taken this to mean leaving windows open throughout the night. While this may generate a pleasant breeze to aid sleep, it also poses a significant security hazard.
Go.Compare's home insurance expert Tamzin Metcalfe cautioned: "One of TikTok's most common heatwave hacks, with hundreds of thousands of views, presents a genuine insurance risk. Leaving a window or door open overnight to help bring a breeze inside might help to keep your rooms cool, but if a burglar enters your property through an open door, any claim you try to make on your insurance will probably be rejected."
Health and Fire Risks: Overnight Fans
Should windows need to remain shut throughout the night, some people may resort to indoor fans and similar devices to maintain comfort while sleeping, though this too carries considerable health and fire risks.
Product Safety Engineer of Electrical Safety First, Giuseppe Capanna, stated: "Households are putting themselves at risk if a fault occurs with their device while they are sleeping. We advise turning your fan off before going to sleep. However, we understand many people will be tempted to keep it on and in this instance, we urge households to ensure they have working smoke alarms in their property."
Electric Shock Danger: 'Portable AC' Hack
A widely shared TikTok tip involves creating a 'portable AC' by attaching wet or frozen towels and ice bags to fans, ensuring the circulated air feels considerably cooler. Capanna cautioned against this so-called 'hack', warning: "Both of these could leave you at serious risk of electric shock, as water risks coming into contact with the motor. We advise everyone to ignore these videos that can garner hundreds of thousands of views."
Draping ice or damp towels over your fan can also trigger mechanical problems should the items become entangled in the blades, or if the added weight causes the fan to tip over. So, in your bid to replicate air conditioning, you could find yourself left with nothing more than a broken fan during the height of a heatwave.
Heatwave Forecast and Impact
The forthcoming heatwave is expected to be concentrated across southern parts of the UK, with temperatures peaking at 34C to 35C. The Met Office has cautioned that the hot and dry conditions could persist for several days, leaving many facing a string of restless, sweltering nights. While England and Wales will bear the brunt of the heat, the warm conditions are also forecast to stretch as far as parts of Scotland and Northern Ireland, where temperatures are expected to reach the upper 20s.
