How the body responds to extreme temperatures, and what we can do to beat the potentially lethal impact
As Europe's record-breaking hot weather eases, the extent of its deadly toll is starting to surface. What can we do to protect ourselves in times of extreme heat and cold?Heatwaves are a subtle disaster. People are not washed away or caught in the flames.

The London Fire Brigade on Tuesday said it had deployed dozens of fire engines to several fires in and around the city, including 30 to a grass fire in east London. Television footage showed one blaze engulfing several homes.
“Firefighters are still meeting the needs of our communities, but declaring a major incident allows us to focus our resources,” the brigade said.
It’s so hot in Europe that roads are literally buckling
The world wasn’t built for this heat.The heat wave, which brought record-breaking temperatures to the UK, France, and elsewhere in the past two weeks, is exposing a frightening reality: Much of Europe isn’t built for extreme heat, or for a climate that’s swiftly changing.
The UK recorded its highest-ever temperature shortly before 12:00 GMT on Tuesday, when it reached 40.2C (104.4F) at London’s Heathrow Airport, according to the UK’s Meteorological Office.
It marked the second time the country’s record temperature had been broken in as many hours after it reached 39.1C (102.4F) in Surrey, southeastern England, earlier on Tuesday. The previous high of 38.7C (101.6F) was recorded in 2019.
The Met Office warned temperatures were “still climbing in many places”, with heat warnings in place for vast swaths of the country, indicating a threat to life.
As the country sweltered, trains were cancelled, schools were shuttered, normally busy city centres appeared quiet and emergency services were reportedly experiencing a surge in 999 calls.
Meanwhile, authorities reported a man had died at a water park in the Cotswolds, in central England, taking the number of deaths recorded in and around water since Sunday to five as people flocked to the seaside, rivers, lakes and swimming pools in a bid to cool off.
The UK often struggles to cope with extreme heat or cold and has been put on a state of national emergency over the unprecedented temperatures, which scientists have attributed to climate change.
Transport Minister Grant Shapps said it would be many years before the country could fully upgrade its infrastructure to cope with higher temperatures, after at least two airport runways showed signs of damage and some train tracks buckled in the heat.
Alexandra Burke snaps family selfies with her newborn baby
Alexandra Burke was the picture of happiness as she enjoyed a family walk with her newborn baby and fiancé Darren Randolph on Tuesday. Three weeks after announcing the birth of their first child, whose name and gender the couple have chosen not to reveal, the new family enjoyed a leisurely stroll on Hampstead Heath.As they arrived back at their car, doting mum Alexandra snapped some selfies with her baby, before sharing a sweet kiss with footballer Darren.
“Infrastructure, much of which was built from the Victorian times, just wasn’t built to withstand this type of temperature,” he told the BBC.
Fires rage as temperatures soar
Elsewhere in Europe, firefighters in southwestern France battled to contain huge forest wildfires as a heatwave rising from the south settled over its western states.
Their efforts came as the country’s national weather service confirmed record high temperatures had been registered in 64 different areas around France on Monday.
Southern and western Germany and Belgium were meanwhile braced for potentially record-breaking temperatures amid the heatwave.
Although the mercury dipped back towards more normal summer levels in Spain and Portugal, firefighters in both countries were still battling multiple blazes.
More than 30 wildfires continued to ravage parts of Spain, with authorities paying special attention to four blazes in the region of Galicia and in Castile and Leon.
In neighbouring Portugal, more than 1,000 firefighters were battling five main wildfires, the biggest of which started in the northern municipality of Murça and spread to two nearby municipalities.
French farms use huge fans to keep dairy cows cool
With new record high temperatures being set across France it isn't just humans that are suffering: even cows high in the mountains need fans to get through the heatwave. Despite sitting at an altitude of 780 metres (2,600 feet), the mercury has climbed to 34 degrees Celsius (93 Fahrenheit) at Nicolas Joannon's farm nestled in the mountains near the eastern city of Lyon. It's too hot for Lila, Glee, Pistachio and the rest of his herd of 35 dairy cows to spend the afternoon outside.But thankfully for them, Joannon has installed two giant fans, measuring 4.5 meters (nearly 15 feet) in diameter, inside his barn.
Further south, in Greece, firefighters tackled 73 fires within 24 hours, the national fire brigade said on Monday. The civil protection authority warned of a very high risk of fires across the country on Tuesday.
The blazes across the continent have already killed several people and forced tens of thousands to flee their homes.
Scientists say climate change fuelling heatwaves
The developments came as the World Meteorological Organization said Europe’s heatwave looked set to peak on Tuesday, but warned temperatures may remain above normal into the middle of next week.
The United Nations agency also cautioned such events were expected to occur with greater frequency in the future due to climate change.
“The direction is clear and in the future these kind of heat waves are going to be normal and we will see even stronger extremes,” WMO Secretary-General Petteri Taalas told a news briefing.
Officials at the same briefing said they expected more deaths among the elderly and those with pre-existing health conditions due to the ongoing heatwave as well as increased challenges for health systems due to more demand.
A study published by climate scientists in June in the journal Environmental Research: Climate concluded that it was highly probable that climate change was making heatwaves worse.
Scientists say global carbon dioxide emissions need to be cut roughly in half by 2030 and reach net zero by 2050 in order to avoid the worst impacts of climate change, but fossil fuels are still heavily relied on and efforts to limit global warming are faltering.
The next big global climate conference – COP27 – will take place in Sharm el-Sheikh, Egypt in November.
Spain has named its heatwave 'Zoe'. As extreme weather events increase, is it time for Australia to follow suit? .
Spain has named its heatwave "Zoe" and London is tipped to endure another stint of blistering conditions. Given the human cost of such events, we asked the experts if giving them a name could help to address Australia's somewhat relaxed attitude to the phenomenon.But change could be afoot — Spain has just named a heatwave for the first time.
