During the 2024 Summer Olympics, the average temperature in Paris increased by 3.1 degrees Celsius compared with 1924, and the carbon dioxide content in the air increased by as much as 40%. In order to adapt to such hot weather, some athletes have specially done targeted training during training, such as using saunas and turning off fans to simulate high temperatures and improving the body's tolerance to high temperatures.
Compared with the scale of the Olympics 100 years ago (only 17 major events and 126 minor events), today's Paris Olympics is much larger (32 major events and 329 minor events). However, in order to echo the Green Olympics and reduce carbon emissions, this time, no air conditioning is installed in the Paris Olympic Village. Instead, trees are planted and ground temperature cooling systems are used to cool down, causing many athletes to worry about high temperatures.
Tipton, professor of physiology at the University of Portsmouth in the United Kingdom, said: "Extreme heat can adversely affect athletes 'performance. After the temperature exceeds 15 degrees Celsius, every 1 degree Celsius increase will reduce marathon performance by about 1 minute. High temperatures may also change athletes 'cognitive abilities in complex decision-making, making people more irritable and excited, disrupting emotions, and reducing exercise ability." (Dong Ming)
