LOS ANGELES -- For the first time in World Cup history, FIFA is mandating all soccer players take hydration breaks to protect them from the threats of extreme heat. But the new rule has sparked criticism from two very different groups.
Some experts have warned that this summer's World Cup -- co-hosted by the U.S., Mexico, and Canada -- could be the hottest in the tournament's history. In response to concerns about extreme heat, FIFA implemented 3-minute hydration breaks midway through each half regardless of temperatures. But some critics say they're interrupting the game's flow and give coaches a chance to shift momentum in their team's favor, while some scientists have said the breaks are too short to make a significant impact on cooling and rehydration when conditions are sizzling.
"When we look at the 3-minute hydration breaks, we're really looking at this as a way to mitigate anything that could potentially lead to an incident or an emergency," said Joshua L. DeVincenzo, assistant director of applied research services at Columbia University's National Center for Disaster Preparedness.
