Heat and humidity make ‘Tokyo Summer the worst in the history of Olympics’

Before the pandemic, heat stroke was the biggest risk to athletes for the Tokyo Olympics, but during the first week of the Games the heat has been compounded by humidity values ranging from 66 to 84%, making it feel much hotter, and limiting the body’s ability to cool down through sweat and evaporation.”When you take into account not only the temperature, but also humidity, I would say that a Tokyo Summer is the worst in the history of Olympics,” says Makoto Yokohari, professor of environment and urban planning at the University of Tokyo and adviser to Tokyo 2020, who spoke to CNN before the Games started.During the Olympics it’s often been 90 degrees or higher, but with humidity, it can feel like triple digits. More than 1,000 deaths were recorded from the country’s 2018 heatwave. This year, from July 19-25, more than 8,000 people have been hospitalized for possible heat stroke. The International Olympic Committee has said it has been taking precautions to deal with the heat, supplying water and shade at venues. In a statement to CNN, it said that the health of athletes is “at the heart of our concerns.” In 2019, organizers moved the marathon to Sapporo to avoid the oppressive weather in Tokyo. But athletes in other sports are already struggling under the Tokyo sun. Last week, Russian archer Svetlana Gomboeva was treated for heat exhaustion when temperatures reached higher than 90 degrees that day. On Wednesday, Russian tennis player Daniil Medvedev was visibly struggling in the heat. When the umpire asked him if he could continue playing, he responded: “I’m a fighter, I will finish the match, but I can die.” Later, he added that he “couldn’t breathe properly. I think that was the most humid day we have had so far.” That same day, Spain’s Paula Badosa was forced to retire from her match with heatstroke and escorted off the court in a wheelchair. “It was a shame to end my participation this way,” Badosa said in comments posted to Tokyo 2020. “The conditions have been demanding from day one, we tried to adapt as best as possible, but today the body has not resisted as needed.” READ: Fields ‘is awake’ after BMX semifinals crash at the Olympics as Kimmann storms to historic goldThe future of the summer games In 1964, the Tokyo Summer Olympics were held in October in order to beat the heat. But in recent decades, the Summer Olympics have been held in July or August. It’s when the sporting calendar is quieter, increasing viewership for the Games. That makes it the ideal months for broadcasters, which pay billions of dollars for rights, to showcase the event. But since then, temperatures have continued to climb. According to a report from the British Association for Sustainable Sport, temperatures in Japan have increased three times as fast as the world average since 1900.Yokohari said these Games should have taken the same route as the 1964 Games. “Having the Olympic Games in midsummer in Tokyo is not something that you should do,” said Yokohari, who thinks Tokyo 2020 should have been postponed until the Fall.Yet researchers warn the problem goes beyond Tokyo. By 2085, most cities could be too hot for the summer Olympics because of climate change, according to research in The Lancet.Going forward, the forecast in Tokyo is more of the same — temperatures will continue to be in the low 86-92° F over the next seven days, potentially reaching 92-93 F over the weekend.However, there are not currently any heat advisories in effect for the Greater Tokyo region, according to the Japan Meteorological Agency.
