Heatstroke countermeasures already being prepped for 2020 Olympics

When the Tokyo Olympics begin on July 25 2020 the rainy season will have just ended the temperatures will hover above 30c and the humidity will 100%.  Just think if don't live here you'll discover just how it feels to be a baked potato. 

Each summer thousands of people are taken to hospital for heat stroke or heat related injuries so how are all those first time visitors to Japan going to cope with environmental conditions they haven't encountered before.  Let's ask the government.

  There has already been criticism over the fact that the Tokyo Olympics and Paralympics will be held during the often brutal Japanese summer months, sparking a great deal of worry for participants and spectators alike, who, while outdoors for extended periods of time, may suffer from heatstroke.The Environment Ministry is planning to install special water sprinkler systems on the tracks and other areas in an effort to fight the scorching heat, TV Asahi reported Thursday. The ministry is also proposing the construction of special roads that absorb large amounts of rain water and through the evaporation of the water into the atmosphere, force the temperature to drop significantly, thus further preventing heatstroke and other ailments during the Games.
Compared to when the Games were held in Tokyo nearly 50 years-ago, the average summer temperature has increased approximately 1.3 degrees centigrade.

The 1964 summer games were held in October hence the differences in temperature.
