UK tourists in Greece warned they 'can't go outside' and 'no one is immune'

UK tourists in Greece have been warned they "can't go outside" as their holidays descend into a nightmare. Greece holidays have turned hellish for British holidaymakers amid a 45C heatwave sparking widespread orders for tourists to stay indoors and avoid activities in the middle of the day.

The Greek Minister of Health, Adonis Georgiadis, said: “People need to understand that climate change is happening and that they need to be very careful." The government minister added: “We have had cases of foreign travellers who lost their lives in Greece.”

Speaking earlier this week, Kyriakos Mitsotakis warned that this summer was on course to be “dangerous” as wildfires broke out across the country, including two near the country’s capital Athens. And it follows a spate of deaths among tourists.

“There is a common pattern,” Petros Vassilakis, the police spokesman for the Southern Aegean, told Reuters, “they all went for a hike amid high temperatures.” "The brain, for me, is the key to it all,” said Damian Bailey, a physiology and biochemistry professor at the University of South Wales. It’s the “master switch” for the body, he told CNN.

“That is a big deal in terms of not getting enough fuel into an engine which is running at high end all of the time,” Bailey said. Kim Meidenbauer, a neuroscientist at Washington State University, warned: “You’re not just talking about potentially getting a little bit too warm and maybe having a sunburn.

“You’re talking about potentially life-threatening (situations), like making poor decisions, having your judgement clouded.” Older people, especially those over 65, are more at risk, because their bodies don’t always thermoregulate as well.

“No one is immune to the health effects of heat,” said Jose Guillermo Cedeño Laurent, one of the research authors and an assistant professor at the Rutgers School of Public Health. “Our brain is an exquisitely sensitive organ,” he said.
