For the first time in World Cup history, FIFA has mandated 3-minute hydration breaks midway through each half to protect players from extreme heat. While medical experts back the move — citing risks of dehydration, heat exhaustion, and even death — critics argue the breaks disrupt gameplay, and some scientists say 3 minutes simply isn't long enough to make a meaningful difference.
For the first time ever, FIFA has made hydration breaks mandatory at the 2026 World Cup, requiring a 3-minute pause midway through each half across all matches in the U.S., Mexico, and Canada. The decision was driven by forecasts of extreme heat and humidity — conditions that medical experts warn could push even elite athletes to dangerous limits.
The science backs the concern. Exertional heat illness can cause muscle cramps, dizziness, confusion, and loss of consciousness, and exertional heat stroke is one of the leading causes of death in athletes. Losing just 2% of body weight to dehydration can impair physical performance, and athletes in the heat can sweat 1–2 liters per hour.
Not everyone is satisfied, though. Some coaches question whether breaks are needed in every match regardless of conditions, while a group of scientists — including experts from Columbia University and the University of Connecticut — co-signed a letter to FIFA urging that breaks be extended to at least 6 minutes for more meaningful cooling and rehydration.
By the Numbers:
Why it matters: As climate change drives hotter global temperatures, the 2026 World Cup is a high-profile test case for how sports organizations adapt to extreme heat. The decisions made here could shape athlete safety protocols across all sports for years to come.
