Extreme Heat Is Putting 2026 World Cup Athletes at Risk
Extreme temperatures peaked when a record-breaking heat dome settled over the U.S. in late June. Amid a heat emergency in Philadelphia, Chelsea manager Enzo Maresca said it was 'impossible' to train properly because of the 98.6°F weather. Midfielder Enzo Fernandez said the 96°F heat during Chelsea's semi-final on July 8—a 3:00 p.m. kick-off at MetLife Stadium like the final—was 'very dangerous.' It was so hot at one point that he 'had to lie down on the ground' after feeling 'really dizzy.'
The severe conditions have raised concerns ahead of the 2026 World Cup hosted in the U.S., Canada, and Mexico. The Club World Cup, held across 12 venues in the U.S., was a smaller dress rehearsal of next year's tournament, but it also tested players' capacity to withstand the realities of a warming world and how organizers and teams plan to protect them.
'Extreme temperatures can be particularly harmful as the body produces heat while exercising and needs to release that heat in order to cool down,' says Madeleine Orr, assistant professor of sport ecology at the University of Toronto. 'But if the ambient temperature and humidity are too high and it's impossible to sweat effectively, that can lead to trouble pretty quickly, starting with symptoms like fatigue, cramping, and nausea, progressing to more serious outcomes like exertional heat stroke if there's no cooling intervention.'
Climate change is making extreme heat an increasingly significant issue across sports. In 2020, Australian rugby league player Keith Titmuss died aged 20 from exertional heat stroke after a pre-season training session. In 2021, Daniil Medvedev raised the prospect of dying to the umpire while playing tennis at the Tokyo Olympics, and 75% of athletes surveyed by World Athletics in 2023 said their health and performance had been negatively impacted by climate change.
The inaugural edition of the expanded Club World Cup has now increased fears that extreme heat will intensify the effects of soccer's already overpacked schedule and how that will impact player welfare (an issue over which FIFPRO—the union representing over 66,000 professional soccer players globally—and domestic leagues are taking legal action against FIFA).
To help alleviate concerns about players being overworked, FIFA claimed to reach 'consensus' over minimum rest periods with players' representatives on July 12, agreeing 72 hours between matches and three weeks holiday between seasons. FIFPRO, however, wasn't invited to the meeting where this decision was made. Those present included officials from organizations expelled from FIFPRO for corruption and former board members who were voted out of office. FIFA did not respond to TIME's request for comment.
Ahead of the Club World Cup final, FIFPRO president Sergio Marchi said in a statement to TIME: 'We have been warning about the overcrowded schedule, the lack of physical and mental rest for players, and the lack of dialogue on the part of FIFA. This way of organizing tournaments … [is] based solely on a logic of economic profitability, not human sustainability.'
FIFA guidelines usually permit one cooling break midway through each half when the Wet-Bulb Globe Temperature (WBGT) reaches 89.6°F. This standard is used around the world to determine when heat reaches a dangerous level, taking into account temperature, humidity, wind speed, sun angle, and cloud cover.
But scientists are concerned that the 89.6°F mandate underestimates player strain because WBGT only considers environmental factors. Following FIFPRO's intervention early in the tournament, FIFA lowered the threshold for cooling breaks at the Club World Cup to 82.4°F, as well as increasing water, ice, and towels around the pitch. While Major League Soccer's WBGT threshold is 84.2°F, FIFPRO states that matches should be postponed if the WBGT exceeds 82.4°F. Three Club World Cup matches exceeded these levels, including Benfica vs. Bayern Munich where temperatures peaked at 104°F in Charlotte, N.C. on June 24. 'I don't think I have ever played in this much heat before,' said 21-year-old Andreas Schjelderup after scoring for Benfica in a 1-0 victory. 'I don't think it's healthy.'
In a June 30 FIFPRO media briefing attended by TIME, the union's medical director Vincent Gouttebarge explained that FIFPRO's WBGT threshold aims to prevent players' core temperature—usually between 96.8°F and 100.4°F—from exceeding 104°F. At this point, there's a risk of heat stroke where 'you don't sweat anymore because dehydration occurs,' he said, 'you have a lack of muscle control, you can barely walk, in some cases your cognitive process is affected, and, in the worst case, you can lose consciousness.'
'FIFA seems quite happy with 89.6°F as a threshold because there have not been any serious heat-related illnesses in the sport up to this temperature,' says Christopher Tyler, reader in environmental physiology at the University of Roehampton, London. 'But this is not the best evidence because players can down-regulate their intensity to lower heat strain,' for example, by sprinting less.
'The speed of the game is not the same, everything becomes very slow,' said Enzo Fernandez ahead of the final. 'Let's hope that next year they change the schedule,' he continued, protecting players and providing fans with a 'beautiful and attractive football spectacle.' Following his side's quarterfinal defeat against Real Madrid in 90°F afternoon heat, Borussia Dortmund manager Niko Kovac echoed this sentiment by suggesting evening kick-offs would raise the intensity of matches 'much higher.' On June 21, Dortmund subs watched the first half of their match against Mamelodi Sundowns from inside the locker room to avoid the blazing midday 90°F heat in Cincinnati, Ohio, conditions Kovac likened to a sauna.
Almost 50% of Club World Cup matches were scheduled at either noon or 3:00 p.m. FIFPRO WBGT estimates shared with TIME, however, determined that if World Cup matches are played during the afternoon in Atlanta, Dallas, Houston, Kansas City, Miami, and Monterrey, there would be an 'extremely high risk' of heat-stress injury.
To estimate the WBGT in 2026 World Cup host locations during an average summer, Queen's University Belfast published a study in January 2025 that used meteorological data from 2003-2022. The researchers found that in June and July—the same period that the World Cup will take place—average temperatures in 14 out of 16 host cities experienced afternoon temperatures that frequently exceeded 82.4°F, while six cities typically exceeded the 89.6°F threshold.
Beyond changing the schedule, other solutions like cooling vests and cold-water immersion are becoming more common. Amid the Philadelphia heat wave, Chelsea used large fans to spray water on the players to cool down, while teams like Real Madrid prepared for the tournament using heated tents to help players acclimatize to conditions they'd have to play in.
Another option is deploying stadium roofs to shield against heat. Five 2026 World Cup stadiums in Atlanta, Dallas, Houston, Los Angeles, and Vancouver have roofs, which FIFA president Gianni Infantino said will 'definitely' be used more for daytime matches. However, only 37.5% of matches are due to take place across these five venues.
FIFA could also schedule matches 'proactively based upon forecast conditions,' says Tyler, but this isn't without its challenges. Last-minute scheduling that's dependent on the weather would create broadcasting and sponsor conflicts by scheduling more matches at times that aren't ideal for the global television audience, particularly in Europe and Asia. This 'scheduling Tetris,' as Orr describes, is even more complex after FIFA expanded the World Cup from 32 to 48 teams, meaning 104 matches instead of 64 and many times more fans.
The Club World Cup isn't the first time that extreme weather has prompted schedule-change requests. At the 1986 World Cup in Mexico, 65% of matches were scheduled to kick off at 12:00 p.m. despite temperatures exceeding 100°F. Before leading Argentina to glory, Diego Maradona said at the time: 'It should be part of the rules once and for all that the organizers should take the soccer players into account. Without us, there would be no spectacular. We are the indispensable ingredient to the World Cup. At least the hours of the games should be set to the time in which we play best, not when there is the most heat.'
Four decades later, the reality of climate change has kicked in and FIFA's critics are hoping the governing body adapts faster to the rising threat of extreme heat. FIFPRO's Marchi said in the statement shared with TIME that the 'extremely hot' periods Club World Cup matches were played in are 'unacceptable conditions' that 'cannot be allowed to happen again under any circumstances' at the World Cup, demanding that FIFA puts players 'at the heart of every decision.'
In FIFPRO's June 30 media briefing, the union's general secretary Alex Phillips said FIFA is 'likely to be more flexible' over World Cup kick-off times after seeing the effects of extreme heat on the Club World Cup, but added that 'we have absolutely no power to force them to.'

Who is leading MLB's MVP, Cy Young and Rookie of the Year races?
Yahoo Sports AM is our daily newsletter that keeps you up to date on all things sports. Sign up here to get it every weekday morning. 🚨 Headlines 🇺🇸 USOPC trans ban: The U.S. Olympic and Paralympic Committee has effectively barred transgender women from competing in women's sports, citing an "obligation to comply" with an executive order issued by President Donald Trump. ⚾️ Holliday gets record bonus: The Rockies gave No. 4 pick Ethan Holliday a $9 million signing bonus, the most ever given to a high schooler and the fourth-most among all draft picks in MLB history. 🏀 Ratings drop: The WNBA All-Star Game drew 2.2 million viewers, which is the second-most ever but still represents a 36% drop from last year (3.44M), when Caitlin Clark (who didn't participate this year) led her All-Star teammates against the U.S. Olympic team. 🏈 Hendrickson holds out: Bengals edge rusher Trey Hendrickson did not report to training camp amid a monthslong contract dispute. The four-time Pro Bowler called Cincinnati's latest offer "atrociously low." 🏈 UFL teams to relocate: The UFL's entire USFL division (Birmingham Stallions, Houston Roughnecks, Memphis Showboats, Michigan Panthers) will reportedly be relocated for the 2026 season. ⚾️ MLB awards watch With MLB's second half underway, and just over two months left in the regular season, let's take stock of the three major awards races. American League MVP: With all due respect to the greatest offensive season by a catcher in MLB history and the Cy Young frontrunner, this one's a slam dunk at the moment. Aaron Judge (NYY): The Yankees captain is having the best season of his career in the midst of one of the greatest four-year runs in league history. He's on pace for 12.3 WAR, per FanGraphs, which would be the best since Barry Bonds in the early aughts. Remove Bonds, and it's the best since Babe Ruth and Lou Gehrig in 1927. Cal Raleigh (SEA): The Mariners backstop is on track to become the first catcher with a 50-homer season, and Judge and Shohei Ohtani are the only players in baseball with a better OPS. Just a remarkable year from Big Dumper. Tarik Skubal (DET): With no other hitter clearly in third place, this goes to the league's best pitcher for two years running. Cy Young: Skubal is vying to become the first back-to-back AL Cy Young winner since Pedro Martínez in 1999-2000, but his competition in Boston isn't that far behind. Skubal (DET): Detroit's ace leads all qualified MLB starters in both strikeout and walk rate, which is outrageous. He also has the best WHIP (0.81) and is tied for the best ERA (2.19) in the AL. Garrett Crochet (BOS): The hard-throwing southpaw leads the majors in strikeouts (165) and is tied with Skubal for the AL's best ERA. And to think he only became a starter last year. Hunter Brown (HOU): While his numbers are still excellent (2.57 ERA, 0.99 WHIP), a couple so-so starts in July have opened the door for guys like Jacob deGrom (2.28 ERA, 0.90 WHIP) and Max Fried (2.43 ERA, 1.01 WHIP) to take his spot. Rookie of the Year: The Athletics might not have a home city or a major league ballpark, but they do have the league's two best rookies. Jacob Wilson (A's): The first rookie shortstop ever voted by fans to start the All-Star Game has the fifth-best average in the majors (.315). Nick Kurtz (A's): He's the only AL rookie with more homers or a higher OPS than Wilson, and with 29 fewer games played this race could tighten considerably. Carlos Narváez (BOS): The Red Sox backstop has the third-best OPS among all AL catchers (.774). National League MVP: At some point, Shohei Ohtani will cede the throne of the greatest player on the planet. We are nowhere near that point as he barrels toward his fourth MVP in five years. Ohtani (LAD): The same guy who leads the NL in HR (36), runs (95) and OPS (.993) also has a 1.50 ERA through six starts since returning from elbow surgery. Pete Crow-Armstrong (CHC): The Cubs' youngster is arguably the best outfielder in the majors, to say nothing of his 26 HR and 28 SB, both top five in the NL. Add it up and he trails only Judge for the MLB lead in WAR. Juan Soto (NYM): All-Star snub and cold start aside, the Mets' $765 million man has looked like himself — aka a top five player — for at least the last two months. Cy Young: As with the AL, this is a two-man race at the moment. Zack Wheeler (PHI): On the one hand, you have Philly's two-time runner-up who leads the league in WHIP (0.88) and strikeouts (164) and is third in ERA (2.39). Paul Skenes (PIT): On the other is Pittsburgh's phenom, who boasts a league-best 1.91 ERA and a stellar 0.91 WHIP that trails only Wheeler's. Good thing we've still got two months left to sort this out. Logan Webb (SF): The Giants' ace is leading the NL in innings for the third straight year, and could nab his third straight top-six Cy Young finish. Rookie of the Year: Who do you choose: the solid player who's been there all season or the lightning rod with just six starts under his belt? Drake Baldwin (ATL): The Braves' backstop has an .837 OPS and 11 HR (both second among NL rookies) to go along with above-average defense behind the dish. Jacob Misiorowski (MIL): The rookie sensation boasts a 2.45 ERA and 0.92 WHIP, which earned him a controversial All-Star selection after just five starts. Hyeseong Kim (LAD): The 26-year-old Korean is batting a scorching .317 through 53 games for the reigning champs. 🎧 Listen: What to watch for post All-Star break (Baseball Bar-B-Cast, Yahoo Sports) 📸 Through the lens Washington, D.C. — A day after winning her doubles match, 45-year-old Venus Williams stunned world No. 35 Peyton Stearns with a straight-sets victory at the DC Open — her first tour-level singles match in over a year and first win since 2023. Unreal. Turn back the clock: Williams is the oldest player to win a tour-level singles match since 2004, when 47-year-old Martina Navratilova won in the first round at Wimbledon. Geneva, Switzerland — Defending champion England is headed back to the Women's Euro final after their 2-1 comeback victory over Italy. They get the winner of Germany-Spain on Sunday. Historic strike: Chloe Kelly's 119th-minute game-winner, a rebound off her own blocked penalty kick, was the latest game-winning goal in Women's Euro history. Mont Ventoux, France — Tadej Pogačar made history on Tuesday in his pursuit of a fourth Tour de France victory, climbing the iconic Mont Ventoux in just 54:51, a full minute faster than the previous record. France gets on the board: Valentin Paret-Peintre won Stage 16 to give the host nation its first stage win of this year's race. Pogačar still holds the overall lead by 4 minutes, 15 seconds over Jonas Vingegaard. 🏀 Yang Hansen has arrived The Trail Blazers shocked the NBA world last month when they drafted Chinese center Yang Hansen with the No. 16 pick. How surprising was the pick? When Yang's name was called, he was sitting in the stands with fans rather than in the green room with his fellow draftees because he hadn't received an invitation. Sin City sensation: Despite being a relative unknown in America, the 7-foot-1 Yang is already a phenomenon in his native country. That was apparent this month in Las Vegas, where he was one of the biggest stars of Summer League, writes Ben Golliver of the Washington Post: Thousands of Chinese and Chinese American fans traveled to Sin City to watch Yang play … Tencent, a Chinese media company, dispatched a documentary crew to follow him … and more than a dozen reporters from China covered his games. Back in China, 5.2 million people watched Tencent's free broadcast of the Blazers' exhibition against the Grizzlies, according to an NBA official, dwarfing the 1.1 million Americans who watched No. 1 pick Cooper Flagg's debut for the Mavericks on ESPN. On Tencent's paywalled service, one of Yang's games drew 3.4 million viewers — 16 times the service's average. And on China Central Television, Yang's summer league games garnered larger average audiences than the national broadcast network's telecasts of this year's NBA playoffs. Next in line: Yang is the third Chinese player to be drafted in the first round, joining Yao Ming (No. 1 in 2002) and Yi Jianlian (No. 6 in 2007). His favorite player is Nikola Jokić and he flashed Jokić-like vision in Vegas, where Yang had a higher assist rate than any of the 15 players picked ahead of him. 🏈 Coming soon: College football!

The lowdown on UEFA Women's EURO 2025 Day 18
After England dramatically booked their place in the European Championship final last night, it is now time to find out who will join them. Before we get into today's action, what happened yesterday? ⏮️ The defending champions put themselves within one game of retaining their trophy with another incredible comeback. After pulling themselves off the canvas against Sweden in the quarter-final, the Lionesses were at it again against Italy, with teenage hero Michelle Agyemang sending the contest to extra-time with a 96th minute equaliser. Azzurre hearts were broken at the death when, with penalties looming, Chloe Kelly's rebound was turned home to send Sarina Wiegman's through. Who is playing today? 👀 Spain aim to add the continental crown to their world title when they take on La Roja progress, it would provide a repeat of the most recent World Cup final, in which they defeated England 1-0. However, if Germany pull off an upset it will throw up a rematch of the Euro 2022 final, when they lost 2-1 to England at Wembley. Player to watch 🔍 In their quarter-final against Switzerland, Aitana Bonmatí showed her quality just when her side needed it most. Player of the Match in Spain's 2-0 win, they toiled for an hour until she came up with a delightful moment of inspiration with her back-heel assist to open up the contest and break the hosts' hearts. "I was always calm," she said assuredly afterwards. The pressure never seems to faze her and she will once more be key to her side's prospects of success. Key storyline 🔑 📸 FABRICE COFFRINI - AFP or licensors Germany's hopes of springing a surprise have been hindered in the build-up by a defensive crisis which could be prove very costly. Kathrin Hendrich will miss out through suspension after her early red card in the quarter-final victory over France and she will be joined watching from the sidelines by Sarai Linder, who picked up an injury last time out. Captain Giulia Gwinn is also an ongoing fitness absentee, while goalscoring hero from the gutsy win over France Sjoeke Nüsken is also suspended. How will Christian Wück cope with the issues? Must-watch video 🎥 The reaction to Ann-Katrin Berger's stunning save in Germany's quarter-final win over France is entirely justified. Fun facts The nations have met once previously at the European Championship, with Germany coming out on top in a 2-0 group stage clash in 2022 Across all their 50 Euros fixtures, Germany have only been beaten five times (winning 38 and drawing seven times) Esther González's strike against Italy made her the first Spanish player to score in four successive Euros games (only Germany's Alexandra Popp netted in more with five) Our prediction 🔮 Germany 1-2 Spain 📸 FABRICE COFFRINI - AFP or licensors

Stoke City are working hard to sign Mamadou Lamine Camara
The Senegalese seems to be on the cusp of a new experience in his professional career. Stoke City are working hard to sign Mamadou Lamine Camara After many years spent with Renaissance Sportive de Berkane in Morocco and North Africa, the Icelandic defensive midfielder looks set for a new experience in England with one of the country's leading clubs, Stoke City, and press reports indicate that the player is currently in England to finalise his move and undergo the necessary medical examinations. Significant interest from several top European clubs Interest in the 22-year-old is not limited to Stoke City, with Crystal Palace, Fenerbahçe, Atletico Madrid and Villarreal in Spain also interested in the player. However, recent press reports suggest that Stoke City are the club that ultimately prevailed in the race for the player's services, despite the many and varied financial offers that were made. According to our sources, a preliminary agreement has been reached between Stoke City and RS Berkane, pending the completion of the deal after the player undergoes medical tests. The Moroccan club hopes to recover between €4 and €5 million for a player currently valued at €1.4 million on Transfermarkt. The young Senegalese talent, who shone this season with Berkane and impressed with the U-23 national team of Les Lions de la Téranga, is on the verge of a major career milestone. A potential move to England could mark a significant step forward in his journey toward the pinnacle of European football.
