No Ice Baths, Just Turkish Saunas: How the Netherlands Prepare for World Cup Heat
The 2026 FIFA World Cup will test more than just tactical discipline—it will push players to their physiological limits. With matches spread across scorching U.S. Cities like Houston, Dallas and Atlanta, teams must innovate to survive temperatures that could exceed FIFA’s WBGT threshold of 32°C (89.6°F), triggering mandatory cooling breaks. The Netherlands, known for their meticulous preparation, have adopted an unconventional solution: Turkish saunas.
While other nations focus on ice baths and hydration protocols, Dutch players will undergo heat acclimatization in saunas—a method endorsed by team physician Edwin Goedhart to build resilience against the oppressive humidity expected in North America. The approach reflects a broader shift in sports science, where traditional cooling methods are being supplemented with heat exposure to enhance performance in extreme conditions.
Key Takeaways
- The Netherlands will use Turkish saunas to acclimatize players to the 2026 World Cup’s extreme heat and humidity.
- FIFA’s WBGT threshold of 32°C (89.6°F) will trigger cooling breaks in matches, but the Netherlands aim to minimize performance drops.
- Teams like Ecuador, accustomed to high-altitude heat, may have an advantage, but the Netherlands’ preparation could level the playing field.
- Coach Ronald Koeman has emphasized tactical flexibility and player rotation to adapt to heat stress.
- The 2026 tournament will feature 16 venues across three countries, with matches played in 10 cities in the U.S., including Houston and Atlanta.
The Science Behind the Sauna
Heat acclimatization is nothing new in sports. Athletes from tennis to cycling have long used saunas to harden their bodies against extreme conditions. However, the Netherlands’ approach is distinctive in its reliance on Turkish saunas, which combine dry heat with high humidity—mirroring the conditions players will face in cities like Houston, where humidity can push the heat index to 110°F (43°C).
Goedhart, a pioneer in sports medicine, explains that traditional ice baths only address symptoms, not the underlying physiological adaptations needed for sustained performance. “When players enter a sauna, their bodies learn to regulate core temperature more efficiently,” he told Dutch media. “This isn’t about immediate relief—it’s about building a tolerance that lasts for weeks.”
The method isn’t without controversy. Critics argue that saunas could increase dehydration risk, but Goedhart counters that the Dutch protocol includes electrolyte-rich hydration plans and gradual exposure, starting with 10-minute sessions that extend to 20 minutes over six weeks.
How Saunas Work for Athletes
- Increased plasma volume: The body retains more fluid, improving circulation and reducing heat strain.
- Enhanced sweat efficiency: Players sweat earlier and more effectively, preventing dangerous overheating.
- Lower heart rate: The cardiovascular system adapts to heat stress, reducing fatigue during matches.
- Mental resilience: Players learn to perform under discomfort, a critical skill in high-pressure tournaments.
Why the Netherlands Chose This Path
The decision stems from the Netherlands’ history of adapting to adversity. In the 2014 World Cup, they faced criticism for their direct, physical style in Brazil’s heat, but their preparation—including altitude training in the Andes—helped them reach the final. For 2026, the challenge is different: not just heat, but humidity levels that can make the air feel like 120°F (49°C).
Coach Ronald Koeman has emphasized that the sauna strategy is just one part of a broader plan. “We’re not just preparing for the heat—we’re preparing for the mental and physical fatigue that comes with playing in these conditions,” he said in a team briefing. “Our players will need to be sharper in the second half, and that starts with how we train now.”
The Netherlands aren’t alone in their heat preparations. Ecuador, for example, regularly trains at high altitudes and in tropical climates, giving them a natural advantage. But the Dutch believe their structured acclimatization will compensate. “We’re not at a disadvantage,” Goedhart said. “We’re just preparing differently.”
What This Means for the Tournament
The 2026 World Cup will be the first to feature 16 venues across three countries, with matches played in 10 U.S. Cities, including:
- Houston, Texas (NRG Stadium) – Expected to be one of the hottest venues, with temperatures often exceeding 95°F (35°C).
- Atlanta, Georgia (Mercedes-Benz Stadium) – High humidity will be the primary challenge.
- Dallas, Texas (AT&T Stadium) – Known for sudden heat spikes, even in early June.
FIFA’s WBGT threshold will play a crucial role. When temperatures exceed 32°C (89.6°F), teams will be allowed one cooling/drinks break per half. However, the real test will be how quickly players recover between breaks. The Netherlands’ sauna training aims to reduce the 5–10% performance drop often seen in high-heat matches.
2026 World Cup Heat Zones
| City | Expected Avg. Temp (°F/°C) | Humidity Challenge | Cooling Break Risk |
|---|---|---|---|
| Houston | 98°F (37°C) | Very High (80%+) | High |
| Atlanta | 92°F (33°C) | Extreme (75%+) | Moderate-High |
| Dallas | 95°F (35°C) | Moderate-High (65%+) | High |
*Data based on historical June averages and FIFA’s WBGT guidelines.
Tactical Adjustments on the Pitch
Heat isn’t just a physical challenge—it’s a tactical one. Koeman has already outlined adjustments:
- Higher defensive lines: Reducing sprinting in the first 30 minutes to conserve energy.
- More possession-based play: Limiting high-intensity pressing in the heat.
- Strategic substitutions: Rotating players like Xavi Simons and Matthijs de Ligt to maintain intensity.
- Customized hydration: Players will carry electrolyte-infused drinks and use cooling vests during breaks.
Koeman also noted that the Netherlands’ 4-3-3 formation provides natural flexibility. “With Frenkie de Jong and Jordy Clasie anchoring midfield, we can rotate players without losing structure,” he said. “That’s crucial when fatigue sets in.”
What’s Next for the Dutch?
The Netherlands’ heat preparations will be put to the test in friendly matches against Saudi Arabia (June 10, 2026) and Mexico (June 15, 2026), both scheduled in high-heat conditions. These games will serve as dry runs for their World Cup strategy.
For fans, the key question is whether the sauna method will pay off. Early indicators suggest it could. In a recent training session, players reported faster recovery times after sauna exposure compared to traditional ice baths. “It’s not just about surviving the heat—it’s about dominating in it,” said Virgil van Dijk, the team’s captain.
FAQ: Your Questions Answered
Common Questions About the Netherlands’ Heat Strategy
- Q: Why saunas instead of ice baths?
A: Saunas build long-term heat tolerance, while ice baths only provide short-term relief. The Dutch method focuses on adaptation, not just recovery. - Q: Will this give the Netherlands an advantage?
A: It levels the playing field. Teams like Ecuador have natural heat advantages, but the Dutch believe their structured acclimatization will match or exceed that. - Q: How does humidity affect performance?
A: High humidity reduces sweat evaporation, making it harder for bodies to cool down. The Dutch protocol includes humidity-controlled sauna sessions to simulate match conditions. - Q: What if a player gets heat exhaustion?
A: FIFA’s medical protocols include immediate cooling stations at every venue. The Dutch have also trained staff in rapid rehydration techniques.
The Bigger Picture
The Netherlands’ approach highlights a broader trend in sports science: prevention over cure. As climate change intensifies, heat management will become a defining factor in major tournaments. The 2026 World Cup may be the first to prove that saunas, not ice baths, are the future.
For the Dutch, the stakes couldn’t be higher. After a disappointing 2022 campaign, Here’s their chance to reclaim their place among the world’s elite. If their heat strategy works, it could redefine how teams prepare for the next generation of World Cups—where the real opponent might not be the referee, but the thermometer.
