As Japan suffers through a heatwave that the government has declared a natural disaster, organizers of the 2020 Olympics are already seeking out ways to help athletes and spectators, should such hot weather recur in that year.

The 2018 summer has been especially hot in Japan, with temperatures reaching 41 degrees Celsius most recently, the highest ever recorded in the country. The extremely hot weather has resulted in 80 deaths and more than 22,000 people suffering from heat stroke.

The 2020 Olympics, based in Tokyo, will run July 24 to August 9. Temperatures in Tokyo in July routinely top 30 degrees Celsius.

Olympics organizers are investigating the possible widespread use of a mist, which could be sprayed on the roads that will be used for the marathon, the walking events, and other outdoor competitions. Already, organizers have rescheduled the marathon, to start at 7 a.m., earlier than planned.

The mist reflects heat and ultraviolet rays. Asphalt commonly retains heat, increasing the temperature of the roads. Such a produce was on display at a recent trade show in Tokyo.
