Hydration Breaks

What a hydration break actually is

A hydration break, also called a cooling break, is a short stoppage that lets players rehydrate, lower their body temperature and take on instructions when conditions are hot. It is one of football's main defences against heat illness.

At the 2026 World Cup each break lasts up to three minutes, and there is one in each half. By convention the referee calls them around the half-hour mark of the first half and roughly the 75th minute of the second, at the next natural stoppage in play. Crucially, the time is added back as stoppage time at the end of the half, so no playing time is lost, the match still delivers its full 90 minutes plus the usual added time.

The breaks are separate from the half-time interval and from normal substitutions or treatment stoppages. During the pause players head to the touchline for water, electrolyte drinks and ice towels, and coaches use the window to reset tactics, which is why a cooling break often doubles as a mid-half team talk.

Wet-bulb globe temperature, explained

Whether a cooling break is needed is not a guess. It is decided by a heat-stress index measured at the stadium called wet-bulb globe temperature, or WBGT.

WBGT combines four things into a single number: air temperature, humidity, wind, and radiant heat from the sun. That makes it a far better guide to danger than the air temperature alone, because in high humidity sweat cannot evaporate, and evaporation is how the body sheds heat. A humid 30 degree afternoon can be more dangerous to an athlete than a dry 35 degree one. FIFA takes WBGT readings before and during matches and uses them to decide on cooling breaks and, in the most extreme cases, whether a match should be delayed.

The thresholds are where the argument lies. The global players' union FIFPRO recommends mandatory cooling breaks once the WBGT reaches about 28 degrees and that matches be considered for postponement at around 32 degrees. FIFA has historically acted at higher readings, which is the heart of the dispute covered below.

Which host cities are hottest

The 16 host cities stretch from the cool Pacific Northwest and Canada down to the humid Gulf Coast and central Mexico, so the heat risk varies enormously from venue to venue.

The four flagged as highest risk, Dallas, Houston, Miami and Monterrey, combine high June and July temperatures with heavy humidity. Several of the worst-affected venues are indoor or roofed and can run air conditioning, and many afternoon matches in hot cities were moved to the evening to avoid the peak sun. The northern and higher-altitude sites such as Vancouver, Toronto, Seattle, Denver and altitude-cooled Mexico City present different, milder challenges. For the full venue picture see our stadiums and host cities guide and the companion piece on the World Cup climate impact.

Is three minutes enough?

The breaks are not universally welcomed as a fix. A growing body of expert opinion says they are too short and too late to genuinely protect players in the worst conditions.

In May 2026 a group of 21 scientists wrote to FIFA arguing that three-minute breaks are too brief to meaningfully bring down a player's core temperature, and that they should be at least doubled. FIFPRO has pushed the same direction, calling for six-minute cooling breaks and for lower intervention thresholds so that breaks kick in, and matches are reconsidered, sooner than FIFA's current practice allows.

The science behind the complaint is straightforward: running in humid heat raises core temperature faster than a short drinks pause can reverse it, so a three-minute stop slows the rise rather than undoing it. Critics also point out that simply moving games to the evening does not solve the problem, because humidity stays high after dark in cities like Houston and Miami. FIFA's counter is that cooling breaks sit within a wider package, roofed and air-conditioned stadiums, evening kick-offs, constant WBGT monitoring and the option to delay a match, that together manage the risk. The disagreement is about where the safety thresholds should sit, and it is one of the defining off-pitch stories of the tournament.

How the heat changes the football

Beyond the safety question, the heat and the breaks reshape how matches are played, especially in the afternoon games at the southern venues.

Extreme heat slows the game down. Teams keep more of the ball, press less and conserve energy, and the tempo drops, particularly in the second half. The cooling breaks themselves become tactical resets, three-minute windows where a coach can change shape or deliver instructions mid-half. Substitutions carry more weight because fatigue arrives faster, and managers rotate harder between matches in hot cities to keep legs fresh across the group stage and into the knockouts.

For neutrals it can mean fewer all-out sprints and a more controlled, possession-heavy rhythm in the heat of the day, which is one more reason so many high-risk fixtures were scheduled for the cooler evening. The teams built for it, the ones with deep squads and players used to humid conditions, gain a quiet edge over a long tournament.
