Fans slam FIFA’s cooling breaks. Why the U.S. World Cup team doctor disagrees

While it may not be remembered as FIFA’s most controversial decision of the 2026 World Cup, the institution of mandatory cooling breaks in all matches has been met with boos and derision, with critics saying the pauses disrupt the game’s flow and offer little benefit in air-conditioned environments.

“They’re in a dome here! Temperature-controlled, climate-controlled — why are we having a break?” fumed one England fan to a radio reporter outside the England-Croatia match in Arlington, Texas, where field temperatures inside AT&T Stadium approached a comfortable 70 degrees Fahrenheit despite an outdoor heat and humidity index near 105 degrees.

But for Dr. Bert Mandelbaum, chief medical officer for U.S. men’s soccer and vice chair of Cedars-Sinai Medical Center’s orthopedic surgery department, the breaks set an important precedent for prioritizing athlete health in extreme heat, even at the highest levels of competition.

“I do think the cooling breaks are an important part of the game. I’m really excited and happy that we are employing those,” he said by phone Tuesday morning, hours after the U.S. team’s 4-1 knockout loss to Belgium.

“Difficult weather environments bring on dehydration and can create severe exhaustion, heat exhaustion, and those [conditions] have tremendous and dire consequences,” Mandelbaum said. “Talk radio could discuss it over and over again, but from our standpoint, the real messaging should be to our communities, our club players, that this is an important part of our game, and the cooling break is how we help manage it.”

Warming climate conditions are forcing changes to human behavior all around the globe, including on the pitch.

Extreme heat kills more people each year than all other forms of extreme weather combined. Elite athletes are not immune to its effects.

As temperatures during a game rise, the circulatory system diverts blood to the skin to lower core body temperatures at the same time that active muscles require oxygen-rich blood. This places extra strain on the heart, which pumps harder to keep up with demand. Sweating players lose electrolytes faster than they can consume them, leading to muscle cramps, fatigue and dizziness.

Virtually all aspects of the game degrade in the heat, Mandelbaum said. Players’ performance, recovery ability and decision making erode. Artificial turf becomes intolerably hot, and the soil in natural grass can harden until it’s like playing on concrete. Air molecules inside the ball expand, making it a harder and faster object. Even fans risk injury: 22 people were treated for heat-related illnesses at a FIFA Fan Festival in Houston last month.

Mandelbaum directs the FIFA Medical Center of Excellence at Cedars-Sinai and was part of the FIFA Medical Committee in 2014, when the first World Cup cooling break was called during a Netherlands-Mexico match in Fortaleza, Brazil.

At the time, the sport’s governing body recommended hydration breaks if temperatures surpassed 102.2 degrees.

This year’s World Cup, hosted across the U.S., Canada and Mexico, is the hottest played since the tournament began in 1930. It has coincided with a withering heat wave in the eastern U.S. With a heat index of nearly 104 degrees at kickoff, the July 4 match in Philadelphia between France and Paraguay is believed to be the second-hottest game in World Cup history, after a 105-degree match in 1994 between Ireland and Mexico in Orlando, according to meteorologist Brad Maushart.

FIFA announced in December that this year’s tournament would be the first in which all matches must pause once in each half for hydration and cooling, regardless of temperature conditions.

FIFA President Gianni Infantino said mandatory breaks equalize playing conditions in all matches. When they haven’t been loudly booing, many fans have noticed that teams often appear to spend as much time strategizing during the pauses as they do hydrating.

Given this, “if we were to use hydration breaks only in those matches where it was too hot and not in the other matches, we would give an advantage or a disadvantage to some of the coaches or some of the teams,” Infantino told Sports News Television.

Harry Brown, a postdoctoral research associate at the University of Sydney’s Heat and Health Research Centre, expressed frustration over the universal breaks in an op-ed in the journal Nature.

“Although it might seem fair to treat all games in the same way, this blanket approach risks undermining trust in heat-safety measures. If breaks are always used, regardless of risk, they stop being meaningful and start looking like routine stoppages,” Brown wrote.

Without active efforts to lower players’ core temperatures, pausing game play may not be enough to effectively stave off heat injury, he wrote. In his own research, Brown’s team compared the effects of passive breaks against breaks with active cooling measures on the health of players participating in 90-minute soccer games in 104-degree heat and 41% humidity.

When players cooled themselves with cold drinks and icy towels during short breaks and took longer halftimes, their core temperatures and cardiovascular strain lowered considerably more than they did after only passive breaks, Brown wrote.

Other physicians argued that even an under-utilized break was better for athletes than nothing at all.

“I would say that it’s better to err on the side of having cooling breaks rather than risk not having them,” said Dr. Miho J. Tanaka, an associate professor of orthopedic surgery at Harvard Medical School who also serves as a team physician for the Boston Red Sox and the New England Revolution.

“Ultimately, an individualized screening or monitoring process may be the safest approach, but we are still far from being able to precisely identify and intervene when an individual player may be at risk,” she said. “Until we are able to do so, having standardized breaks is a step in the right direction, as long as teams and players are informed when to escalate their level of concern and take action when more aggressive measures are truly needed.”

While a cooling break is rarely medically necessary inside a climate-controlled indoor stadium, Mandelbaum said it still sends a valuable message to players around the world: If hydration breaks are a part of the sport’s biggest event, they should be allowed at every other level of play.

“Not only is [the hydration break] a good thing, it’s a necessary thing,” Mandelbaum said. “This is the world’s game … we have to figure out how to help players at all levels and ages to have the ability to thermoregulate, hydrate, how to do it well.”

Nobel Prize winner leaving UC Berkeley for new role in China

Nobel Prize recipient Omar Yaghi is leaving his role at UC Berkeley to lead the development of a new artificial intelligence institute at Tsinghua University in Beijing, the Chinese university announced.

Yaghi will head the AI Chemistry and Materials Research Institute at Tsinghua, where he was appointed an honorary professor in 2022. Known as AIMATRY (AI × Materials × Chemistry), the new center will focus on material design and synthesis through artificial intelligence, according to a statement from the university.

In 2025, Yaghi shared the Nobel Prize in chemistry with Susumu Kitagawa of Kyoto University and Richard Robson of the University of Melbourne for their development of metal-organic frameworks, a type of super-porous material in which metal ions and carbon-based molecules combine to form crystals with exceptionally large surface areas.

The material has the potential to combat climate change by capturing and storing carbon or other pollutants, and by extracting water from the atmosphere in water-scarce areas. Upon awarding the prize, a member of the Nobel committee likened the technology’s ability to store enormous amounts of stuff in seemingly compact spaces to Hermione Granger’s enchanted handbag in the Harry Potter series.

Yaghi’s Irvine-based company, Atoco, has said it will start taking orders later this year for its technology that harvests water from the air.

A representative for Yaghi said he was not yet available to respond to questions.

China is one of several countries that has been actively recruiting scientists from the U.S., where the Trump administration has slashed science funding, suspended research grants, fired science advisors and tightened immigration restrictions.

“For many, many years, our funding was very competitive; if you worked hard and you were doing good research, you would get funding,” Yaghi said of the U.S. in an interview with Scientific American earlier this year. “The current state is not so encouraging because of the cutting back on grants and support of science by the very agencies that many university researchers rely on.”

Yaghi was born in Jordan to Palestinian refugees, and immigrated to the U.S. when he was 15 to study.

“We’ve learned over and over in human civilization that scholars can move across borders,” Yaghi told the New York Times last year. “This is how knowledge spread and how vast regions of the world lifted themselves out of poverty.”

Trump administration seeks to limit federal funding that doesn’t ‘advance’ presidential policies

Trump administration seeks to limit federal funding that doesn’t ‘advance’ presidential policies

A new rule proposed by the White House Office of Management and Budget would fundamentally overhaul the way federal grants are awarded and overseen — a sweeping change that one scientific society said “would all but end the use of scientific merit in the selection of grants and programs across the government.”

Proposed in late May, the rule would give political appointees unprecedented control over federal grants for research, education and infrastructure, and specifies that government funds can only be spent on projects “aligned with administration policies and priorities,” according to a copy of the proposed rule.

The rule would also restrict research topics, limit U.S. scientists’ ability to collaborate with colleagues in other countries and make it easier for the government to suspend or cancel grants at any time.

The changes are intended to improve “transparency, accountability, and oversight for Federal awards” while “ensuring that American tax dollars are not wasted or misused,” according to the White House office.

But critics say that if the rule is implemented, the final sign-off for grants will no longer be in the hands of subject-matter experts within individual agencies, but in those of political appointees.

“This touches all parts of American life,” said Dr. Eric Rafla-Yuan, a psychiatrist who practices at the Veterans Administration and San Diego County’s psychiatric hospital.

“Control of how all of the federal grants and programs are funded will fall under a small group of highly partisan individuals who would have very few limits on how they spend these billions of taxpayer dollars,” said Rafla-Yuan, who also chairs the Committee to Protect Public Mental Health advocacy group. “This touches everyone’s life, even if they don’t realize it.”

OMB published the proposed rule May 29, opening a 45-day comment period that closes July 13.

Opposition to the proposed rule has mobilized multiple sectors of society. Professional groups representing cancer researchers, civil engineers, county governments, medical schools, housing agencies, city and municipal governments, nonprofits and others have publicly expressed concerns about potential consequences.

By midday Thursday, the Federal Register logged nearly 100,000 comments about the proposal, many of them expressing concern.

“I understand the need for oversight, fiscal responsibility, and accountability. That is not the issue,” wrote Jack Feldman, a neuroscientist who holds the David Geffen School of Medicine Chair in Neuroscience at UCLA. “The issue is whether scientific research is to be judged by scientific merit, or whether it can be approved, denied, or terminated according to broad political criteria that may change from one administration to the next.”

Crucially, the rule converts policies governing federal grants from “guidance” into binding regulations that all agencies would be required to follow. It would give political appointees power to override federal agencies’ merit-based reviews and mandate that a political appointee review decisions to ensure that all awards “demonstrably advance the President’s policy priorities.”

The elevation of political appointees in what were previously merit-based decisions has alarmed many scientists.

“The proposed rule changes would all but end the use of scientific merit in the selection of grants and programs across the government,” read a statement from the Planetary Society, a nonprofit dedicated to space research.

Researchers and science groups have also expressed concern about a section of the rule prohibiting the promotion of “theories of disparate-impact liability” — a legal concept that refers to policies that appear neutral but cause disproportionate harm to certain groups.

The section’s vague language and many loopholes could have a chilling effect on any research that studies the effects of a disease, policy or public health intervention on any specific group of people, Rafla-Yuan said.

As an example, he said, “if there’s a specific age range that is at higher risk for suicide, and we want to figure out, well, what’s going on with people that are aged 14 to 19 … we can’t do that under the wording in this rule.”

New restrictions on collaborations with scientists in other countries would hinder opportunities for U.S. researchers and limit innovation, said Joanne Padrón Carney, chief government relations officer for the American Assn. for the Advancement of Science.

“Science is a global enterprise. Especially in biomedical and public health fields, diseases don’t care about borders or government policies,” she said.

California’s congressional delegation sent a letter Wednesday asking OMB to rescind the proposal, outlining concerns about its impact on scientific innovation, U.S. competitiveness and the fiscal stability of local governments, many of which rely on federal grants for local services.

The proposed rule grants the federal government broad powers to suspend or cancel grants for any reason, introducing “unprecedented unpredictability into local governance,” the lawmakers wrote, “leaving vital infrastructure projects unfinished and abandoning vulnerable populations who rely on these services.”

Republican Sen. Susan Collins has also asked the White House to withdraw certain parts of the letter and extend the public comment period, saying the proposed rule as written would “harm small and rural communities, undermine scientific and biomedical research, and conflict with Congress’ control over the federal funding process.”
