Olympic Tokyo is rated as an unprecedented olympic Olympic period, causing athletes to be at risk of dehydration, rapidness and heat shock.

Before the opening ceremony of the Olympic Tokyo 2020 took place on July 23, Russian Archers Svetlana Gomboeva fainted in the qualifiers due to exhaustion because of hot sunshine.

Feeling almost as you are in the sauna, Makoto Yokohari, Professor of the Urban Planning Department of Tokyo University, cum advisor to the Olympic Tokyo Organizing Committee, said.

Russian player Daniil Medvedev in the game belongs to the Olympic framework in Tokyo, Japan, on July 24.

This is a consequence of the heat, when the heat accumulates and stuck in the city center, causing the temperature in urban areas to rise.

On the night, when the temperature lowered, the road surface released the hot slightly accumulated throughout the day.

The hot sunshine summer is not strange in Tokyo, but experts think that it cannot ignore human-caused climate change.

Over the years, Tokyo has planned for a hot sun Olympic, as the organizer in 2019 decided to move the Marathon exam to Sapporo city, 800 km north of the capital.

However, with the condition of the frequency and the heat intensity in cities around the world continues to increase, Yokohari is pessimistic about the future summer Olympications.

We call the summer Olympics, but the International Olympic Committee should probably adjust the time of the autumn or early spring.
