Korea's national football team is among the best placed to endure the climate in Brazil during the 2014 FIFA World Cup, Bloomberg says.
The national team trained in Miami, Florida to help them adjust to the hot and humid weather in Brazil and make sure no shocks to the system play havoc with their performance.
Bloomberg came up with "discomfort score" for each country's matches based on the expected temperature at kickoff, humidity, cloud cover, altitude, and angle of the sun.
Korea stands to benefit from the most comfortable weather of all 32 participating countries on match days, with a discomfort score of 16.
The average daytime high in Brazil in June is 30 degrees Celsius with a humidity of up to 70 percent. That is a severe test for players' stamina.
But Korea will face its opponents in the three cities where the weather will be relatively favorable. Among the countries grouped with Korea, Algeria had the second lowest score of 16.8 points, Russia was 12th with 37.6 points, and Belgium 15th with 46 points.
Strong contenders for the title are struggling with the weather, which can tip the scale in a tightly contested group like Group D -- Costa Rica, England, Italy, and Uruguay -- where at least three teams are thought to be almost equally matched.
Four-time World Cup champion Italy had the highest discomfort score of 91.1 points.
Kim Eun-kuk at Korea National Sport University said, "In hot and humid weather, even the strongest athletes can suffer muscle cramps or reduced stamina. How players adjust to the weather is going to be a major factor in their performance during this year's World Cup."
