Searing heat, dripping humidity, and face masks: it’s going to be a sweaty Tokyo Olympics and while coronavirus measures are top priority, heatstroke remains a serious risk, experts warn.
Long before the pandemic forced Tokyo 2020’s postponement, the Japanese capital’s brutal summer heat was the main health concern for organisers.
While the Games have been held in places that are hotter or more humid than Tokyo, including Athens and Beijing, Japan’s sweaty summers offer both, in an unpleasant and sometimes deadly combination.
Organisers have moved the Olympic marathon and racewalks to the northern island of Hokkaido, hoping to outrun temperatures that can hit 37 degrees Celsius and humidity over 80 percent.
And with fans now banned from nearly all Games events over virus fears, the risk of large crowds sizzling in the sun is no longer a concern.
But athletes, who will have little time to acclimatise because they are only allowed to arrive just before competition, could still suffer.
“Holding the games during July and August… was a serious issue even before the coronavirus pandemic,” Haruo Ozaki, chairman of the Tokyo Medical Association, told reporters recently.
“There are still high risks of heatstroke at events such as competitive walking, triathlon, and beach volleyball,” even after moving the marathon and racewalking, he warned.
At test events in summer 2019, organisers rolled out a variety of anti-heat measures: 1,360 tonnes of ice to cool athletes, tents for shade, ice cream for volunteers and mist fans and artificial snow for spectators.
Even so, several people were treated for suspected heatstroke at a beach volleyball event and 10 people including athletes fell ill at a rowing test event.
