Is colts cold plunge calm the secret weapon for better performance on the field? The Indianapolis Colts are banking on it. On September 1, 2025, the team rolled out an innovative pre-game ritual in Indianapolis, IN, stationing 15-yard mobile plunge tanks outside their locker room. These icy baths are designed to lower players’ core temperatures and steady their nerves before kickoff. Early results suggest it’s working, with coaching staff and players noticing sharper focus and fewer mistakes. This bold move could redefine how teams prep for high-stakes games.
Mobile Plunge Tanks: A Game-Changer

The Colts’ new setup isn’t just for show. These 15-yard mobile plunge tanks, parked right outside the locker room, are a calculated effort to optimize player readiness. The tanks are filled with frigid water, creating an immediate physical reset for athletes stepping in. Team officials believe this isn’t just about cooling off—it’s about recalibrating the body and mind before the intensity of game day takes over. The accessibility of the tanks ensures every player can take part in this chilling pre-game routine.
Core Temperature Drop: The Science Behind It

The impact of the cold plunge is measurable. Data collected during the initial rollout on September 1, 2025, shows players’ core body temperatures dropping by an average of 1.2°C after a brief session in the tanks. This isn’t just a superficial chill; lowering core temperature can slow metabolic processes temporarily, helping to reduce pre-game jitters. Sports scientists note that such a drop can trigger a calming effect, preparing athletes for the mental demands of competition. The Colts are leveraging this physiological edge to their advantage.
Heart Rate Variability Boost: A Sign of Calm

Another striking result from the colts cold plunge calm initiative is the improvement in players’ heart rate variability (HRV). Post-plunge measurements revealed an average increase of 10 points in HRV, a key indicator of the body’s ability to adapt to stress. Higher HRV often correlates with better emotional regulation and focus—critical traits for athletes under pressure. For the Colts, this spike suggests the cold tanks are doing more than just cooling bodies; they’re helping players stay composed when the stakes are highest.
Coaching Staff Sees Behavioral Shifts

The Colts’ coaching staff has been quick to praise the cold plunge program. They’ve observed noticeably calmer starts to games since implementing the tanks. Players appear more centered during warm-ups and early plays, a shift the staff links directly to the pre-game ritual. This mental clarity seems to translate to on-field performance, with coaches noting a reduction in avoidable errors. The cold plunge is becoming a cornerstone of their strategy to maintain discipline under pressure.
Fewer Penalties: A Tangible Outcome

One of the most concrete benefits reported by the coaching staff is a drop in penalties. While exact numbers aren’t yet available, the staff credits the cold plunge with helping players avoid costly mistakes driven by nerves or overexcitement. Early-game penalties, often a result of lapses in focus, have reportedly decreased since the tanks were introduced. For a team aiming to tighten up their gameplay, this outcome of colts cold plunge calm could be a critical factor in securing wins.
Injury Recovery Research on the Horizon

The benefits of the cold plunge may extend beyond game-day performance. Indiana University’s sports medicine department is set to publish mid-season findings on how cold therapy correlates with injury recovery among Colts players. While the study is still underway, the focus will likely explore whether regular cold plunges reduce inflammation and speed up healing after physical strain. This research could provide deeper insights into the long-term value of the tanks for player health and durability.
Cold Therapy in Sports: A Growing Trend

The Colts aren’t alone in exploring cold therapy, though their mobile tank setup is uniquely ambitious. Across the U.S., teams and athletes are increasingly turning to ice baths and cryotherapy to manage stress and recovery. Studies from institutions like the National Center for Biotechnology Information highlight cold therapy’s potential to reduce muscle soreness and improve mental resilience. The Colts’ program aligns with findings from organizations like the American Orthopaedic Society for Sports Medicine, which advocate for innovative recovery methods in professional sports.
What’s Next for the Colts’ Cold Plunge Program?

As the 2025 season progresses, the Indianapolis Colts plan to refine their cold plunge initiative. Feedback from players and ongoing data collection will shape how often and when the tanks are used. The collaboration with IU’s sports medicine team could also yield protocols that other NFL teams might adopt. For now, the Colts are setting a precedent, proving that a few minutes in icy water might just be the edge a team needs to stay cool—both literally and figuratively—in the heat of competition.
