The most common reason people die in hot weather - and it's not heatstroke The UK is in the grip of a heatwave, with temperatures set to soar to 40 degrees in some areas. The Met Office has issued red weather warnings for parts of England and Wales Britain is sweltering under a late June heatwave, with some regions braced for blistering 40-degree temperatures. The Met Office has issued red weather warnings for sections of England and Wales for today, Wednesday, and Thursday, while the UK Health Security Agency has released its own red health alerts. Schools nationwide have shut, and temperatures could approach the UK's all-time high of 40.3 degrees, recorded in Lincolnshire in July 2022, and are predicted to obliterate the previous June record of 35.6 degrees, established in Hampshire in 1976, reports the Express. BBC journalist and former weather presenter Lara Lewington highlighted the biggest danger during scorching weather - and it's not heatstroke. She outlined the concern in a TikTok video. She said: "Why do people die when the weather gets hot? The main reason isn't heat stroke or dehydration. There's another reason that accounts for more deaths in heatwaves, and that's heart failure. When you get hot, your body directs more blood towards your skin so that you can radiate some of the heat away. "To do this, your heart has to beat harder and faster. And, for the elderly or those with pre-existing conditions, this can simply push their system to its limit, leading to an increased risk of stroke, heart attack, or heart failure. So as we head into the heatwave this week, make sure you stay hydrated, keep cool, and check in on any elderly or vulnerable relatives." Which areas are affected by the red heat warning?

If you do have to go outdoors, apply high protection sunscreen regularly, wear a wide-brimmed hat and seek shade. - Keep your home cool: keep windows and curtains closed in rooms that face the sun during the day. Open windows (if it is safe to) when the air feels cooler outside than inside, for example at night, and try to get air flowing through your home. - Limit any strenuous physical activity, or plan physical activity for times of the day when it is cooler, like the early morning or evening. - Avoid hot, closed spaces like stationary cars. - Wear loose, light-coloured clothing made from breathable natural fabrics such as cotton or linen. Dark colours and synthetic materials absorb and trap heat. - Stay hydrated throughout the day, not only when thirsty. If sweating heavily, consider rehydration drinks to replace lost electrolytes. Limit caffeine and alcohol, which contribute to dehydration. - Spray or sponge your skin with cool water. Cold packs wrapped in a cloth and put under the armpits or on the neck can also help. - Turn off non-essential electronics. TV, laptops and chargers generate heat.
