Key Highlights

• Matthew Mayich collapsed during an Arizona State University outdoor workout in August and remains critically ill; teammates allege multiple policy violations, including lack of on-field wet bulb globe temperature (WBGT) measurement and absence of cold-water immersion equipment.
• Exertional heat stroke is a preventable, rapidly progressing medical emergency for which cold-water immersion is the established lifesaving treatment; yet policies and implementation vary widely across professional, college, high school, and youth sports.
• Climate-driven increases in extreme heat and the spread of heat-retaining synthetic turf are raising risk across all levels of sport; consistent adoption of WBGT monitoring, acclimatization protocols, and emergency rehearsal could prevent future tragedies.

Introduction

On the morning of August 20, at Sun Devil Stadium in Tempe, Arizona, 21-year-old hockey player Matthew Mayich stepped onto the field for his first official practice with Arizona State University’s program. Temperatures were already approaching 90°F. What followed — a prolonged, intensive workout led by a guest trainer, visible signs of distress in multiple players, and, ultimately, Mayich’s collapse — has become a flashpoint for a larger conversation about heat safety in athletics.

Mayich’s situation is not an isolated accident. It sits at the intersection of growing environmental risk, shifting playing surfaces, uneven institutional safeguards, and human error. The university’s internal timeline and the letter from anonymously named teammates present sharply different accounts of what occurred, but both point to a core fact: a young athlete suffered a collapse after strenuous exertion in dangerous heat conditions. His family believes exertional heat stroke left him on life support. Teammates say key protections called for in ASU’s own policies were not in place.

This incident illuminates a pattern observed over decades. After Korey Stringer, a Minnesota Vikings lineman, died of heat stroke in 2001, sport medicine specialists designed clear best practices for prevention and treatment. Those measures — wet bulb globe temperature (WBGT) monitoring, staged acclimatization, mandatory hydration and shade breaks, and immediate access to cold-water immersion tanks — work when they are followed. They fail when they are treated as optional. The consequence is not theoretical: extreme heat is already becoming more frequent and intense, and synthetic playing surfaces amplify heat stress. Without consistent policy adoption, training, and enforcement, more athletes will face the same peril that landed Mayich in the hospital.

The following reporting synthesizes the available accounts and research to explain what exertional heat stroke is, why it’s becoming more common, where policy gaps exist, what good practice looks like, and what accountable institutions must do now.

What happened at ASU: a timeline of alleged failures

The available accounts converge on a set of troubling details. On August 20, at roughly 7 a.m., Arizona State hockey players performed at least 45 minutes of repetitive, high-intensity conditioning in direct sun. A guest trainer, former Green Beret Tim Ziesel, led exercises that included push-ups, planks, sprinting, and partner carries. The session concluded with a medicine ball run. Temperatures reportedly climbed toward 90°F.

According to the university’s public timeline, staff initially treated Mayich with iced towels and cool water, then sprayed him with a garden hose; he was responsive at first, then declined and was transported by ambulance to the hospital. The university also acknowledged procedural irregularities and later placed head coach Greg Powers on paid leave.

Teammates, writing in an anonymous letter delivered through counsel, say the workout lasted 75 minutes — not 45 — and that athletes showed significant signs of heat illness before the final drill. The letter accuses the athletic department of bypassing required approvals for the outside trainer, failing to measure on-field WBGT, not providing recommended water and shade breaks, and lacking immersion tubs and ice chests. They report that by the time paramedics arrived, Mayich had been down for 17 minutes and “nothing effectively cooled him.” The letter asserts that staff sprayed him with “warm water” from a garden hose before professional responders assumed care.

ASU’s internal report acknowledged some procedural mismatches — such as the absence of a written plan for an outside consultant and reliance on off-site weather sensor data instead of on-field WBGT measurements — but stopped short of identifying violations that directly led to Mayich’s collapse. The university has appointed a former state supreme court chief justice, Scott Bales, to review planning, policies, and responses related to outdoor athletics. Mayich’s family has requested the review be expanded to include an independent investigation into the specific events of the workout and whether rules were violated.

The competing narratives raise two immediate questions: was the workout planned and supervised according to ASU policies, and did the response to Mayich’s collapse provide the rapid, evidence-based cooling required for the best chance of survival?

Exertional heat stroke: the medical facts and why time matters

Exertional heat stroke occurs when a person exercising intensely generates more internal heat than the body can dissipate. Core temperature rises to levels that damage organs and the brain. Symptoms range from dizziness, confusion, and collapse to seizures, loss of consciousness, and multi-organ failure. Diagnosis requires an accurate core temperature reading; rectal thermometry is the clinically accepted standard during suspected exertional heat stroke because it reliably reflects internal temperature. Peripheral measures like oral or tympanic readings can be misleading.

The single most effective immediate treatment is cold-water immersion. Studies and clinical consensus show immersion delivers rapid cooling rates that significantly reduce morbidity and mortality compared with cooling via air conditioning, fans, or iced towels alone. Research indicates immersion can reduce internal temperature far faster than passive cooling; where properly applied, it often makes the difference between full recovery and permanent damage.

Speed is decisive. Every minute without adequate cooling raises the risk of irreversible injury. In the case of Korey Stringer, a failure to initiate cold-water immersion and to obtain accurate internal temperature measurements contributed to a delayed and inadequate response. The Korey Stringer Institute and other researchers have documented numerous instances where timely immersion prevented deaths or severe outcomes, underscoring that the tools to save lives exist — but only if teams and institutions have them on hand and have practiced using them.

At ASU, teammates say an immersion tub was not present on the field and that several minutes elapsed while bystanders applied limited cooling measures. If those accounts are accurate, the absence of rapid, evidence-based cooling would represent a critical missed opportunity.

Why heat risk is increasing: climate change, urban heat, and synthetic turf

Extreme heat events are rising in frequency, intensity, and duration. Attribution studies show that the probability of very hot conditions has increased across many regions; in some World Cup host cities, the chance of extreme heat at match time has at least doubled compared to decades past. Athletes who train or compete outdoors increasingly face conditions that exceed historical norms.

Two additional contributors amplify that risk. First, urban and stadium microclimates — where concrete, asphalt, and limited airflow elevate ambient temperatures — can make conditions worse than regional weather reports imply. Second, the proliferation of synthetic turf matters. Artificial turf can soar well above air temperatures because dark, porous surfaces trap solar radiation and retain heat. Reported surface temperatures at a recent NFL game in Nashville reached 157°F, enough to melt footwear and produce immediate heat-related distress among players.

These combined trends mean that relying on traditional measures — such as ambient temperature or humidity reported from a weather station miles away — underestimates the physiological stress players experience on-field. Wetted or shaded conditions, wind, solar radiation and surface temperatures all alter heat load; that’s why WBGT is the preferred metric for assessing heat stress.

WBGT, acclimatization, and the metrics that should govern decisions

Wet bulb globe temperature (WBGT) is the gold standard for quantifying environmental heat stress because it accounts for temperature, humidity, wind speed, sun exposure and radiant heat. Unlike the heat index, WBGT reflects the thermal load an athlete actually experiences.

Best practice requires on-site WBGT readings taken at field level. Studies demonstrate that off-site readings from regional weather stations systematically understate on-field WBGT by several degrees, a difference large enough to change the recommended precautions. Where WBGT readings fall into higher categories, organizations should reduce practice intensity, shorten session duration, mandate rest and shade, or cancel activities altogether.

Acclimatization is equally crucial. Physiological adaptation to heat requires repeated, gradually increasing exposure over seven to 14 days. That process lowers heart rate and core temperature for a given workload and reduces the risk of exertional heat stroke. A player who arrives in a hot climate and immediately undertakes intense outdoor conditioning has not had the chance to physiologically adapt, even if informal activity occurred indoors.

Arizona State’s own policy recommended acclimatization and on-field WBGT measurement. Critics of the August workout say neither was adequately observed. The timing of NCAA restrictions — which delayed official outdoor practice until August 20 — meant players had limited legitimate opportunity to build heat tolerance. Voluntary, air-conditioned indoor workouts do not produce the same physiological adaptations needed to tolerate prolonged outdoor exertion.

Where policy works: Georgia’s high school reforms and professional standards

Policy adoption is not the limiting factor in every case. Georgia’s state-level reforms after a string of high-school fatalities demonstrate that systematic change reduces heat-related illness and death. In the early 2000s, Georgia had among the highest rates of heat-related high school football fatalities. The state implemented mandatory WBGT monitoring, acclimatization schedules that limit the intensity and duration of early-season practices, and strict limits on equipment and conditioning during initial practice days. Within three seasons, heat-related illness rates fell substantially.

Professional leagues have taken varying approaches. The NFL mandates WBGT monitoring when hot weather is possible, requires immersion tubs and rectal thermometry as part of the toolkit, and expects teams to rehearse emergency response plans. The league’s medical leadership cites near-universal compliance with those standards among clubs, and the NFL encourages teams to adopt additional safeguards at their discretion.

Other professional organizations, however, set enforceable thresholds less clearly. The National Women’s Soccer League, for example, stipulates mandatory hydration breaks and possible game delays at specific WBGT thresholds, with enforceable sanctions for noncompliance. FIFA’s summer World Cup water breaks drew criticism from some observers who perceived a tension between player welfare and commercial broadcasting objectives; that episode highlighted the risk when safety measures intersect with revenue-driven event management.

The variance between the professional level — which often has personnel, money, and mandated procedures — and high school, youth, or volunteer-run leagues — which may not — explains much of the exposure gap. Where resources and strict enforcement exist, protective measures are effective. Where they do not, athletes remain at risk.

Where policy fails: patchwork rules, resource limits, and cultural resistance

Across the U.S., heat-safety policy exists in a patchwork. No federal mandate governs heat safety for youth or scholastic sports. National organizations issue guidance, but states and school districts determine adoption. The Korey Stringer Institute’s state-by-state scoring shows wide disparity: some states approach best practices; others score poorly. Several northern states lag in policy adoption, often under the mistaken belief that cooler regional averages eliminate risk. Heat waves and sudden spikes can catch those regions unprepared.

Resource constraints present another barrier. Accurate WBGT gauges and immersion tubs cost money. Athletic trainers are not uniformly available, especially in smaller high schools or recreational leagues. Volunteer coaches sometimes hold entrenched cultural views that equate toughness with risk-taking; some fear that limiting practice time will erode competitiveness. Those concerns can make administrators reluctant to implement or enforce stricter protocols.

The NCAA’s posture exemplifies a related problem. The association issues recommendations but stops short of mandates. Guidance language peppered with “should,” “may,” and “recommended” creates ambiguity. Institutions can claim compliance while sidestepping specific, enforceable practices such as mandatory WBGT measurement or guaranteed access to immersion. That discretion leaves gaps that become lethal when on-the-ground decision-making falters.

What the ASU case says about institutional responsibility and oversight

The ASU controversy spotlights several institutional weaknesses. First, approval processes for outside consultants appear not to have been followed in a manner that ensured oversight of a high-risk outdoor workout. Policies that require written activity plans and pre-approval become meaningless if they are ignored or inadequately enforced.

Second, ASU’s reliance on off-site weather sensors and WBGT estimates undermines situational awareness. On-field WBGT measurement is inexpensive compared with the cost of a life and far more accurate in practice. A 2021 ASU study found field-level WBGT readings were often significantly higher than regional station estimates — a technical point with immediate practical consequences.

Third, the absence of an immersion tub and failure to execute rapid immersion cooling — as alleged by teammates — would constitute a grave procedural breakdown. It is not enough for a policy to exist in print if the gear is not maintained, located accessibly, and staff are not drilled in its use. Emergency response requires rehearsal; complacency kills.

Finally, transparency and accountability matter for prevention. Independent reviews with clear mandates and public reporting can identify systemic failures and force corrective action. ASU’s decision to commission a review is a step forward, but the university’s own internal timeline and the family’s call for a broader, independent investigation suggest skepticism about whether that internal review will fully address culpability and corrective remedies.

Practical interventions that save lives: what must be implemented and how

A clear, evidence-based set of actions can prevent many heat-related tragedies. Institutions that adopt and enforce these measures can dramatically lower risk.

1. On-field WBGT monitoring and clear thresholds. Take field-level WBGT readings before and during workouts. Use pre-established thresholds to scale activity intensity, duration, and equipment. Make the thresholds enforceable and visible to coaches, trainers, and players.
2. Mandatory acclimatization protocols. Implement a staged ramp-up in practice intensity over 7–14 days for new arrivals and for the start of each season. Limit full-contact and high-exertion drills during initial days.
3. Cold-water immersion availability and drills. Have immersion tubs, ice, and trained staff on-site whenever outdoor activities are likely to produce heat stress. Regularly rehearse rapid-immersion protocols so that teams can execute cooling within minutes, not hours.
4. Accurate, immediate core temperature assessment. Equip medical staff with rectal thermometers in settings where exertional heat stroke is possible and train them in their clinical use and privacy considerations.
5. Hydration, shade, and enforced rest breaks. Ensure accessible water and shaded rest areas. Structure workouts so that breaks are automatic rather than optional and communicate that players who miss hydration opportunities should not be penalized.
6. Staff training and accountability. Make athletic trainers and medical personnel non-negotiable for high school and collegiate programs. Require documented emergency-action plans and third-party audits for adherence.
7. Data-driven decision-making and transparency. Collect and publicly report data on WBGT readings, practice modifications, and incidents. External review and public disclosure create incentives for adherence.
8. Address surface heat. When using synthetic turf, adopt stricter WBGT thresholds for activity and consider cooling strategies such as watering surfaces where feasible and safe. Reassess the use of dark-colored turf in hot climates.
9. Education for athletes, parents, and coaches. Teach recognition of early signs of exertional heat illness and create a culture where reporting symptoms is encouraged and free of stigma.

Resource barriers matter, but so do priorities. The Georgia example shows that policy can dramatically reduce fatalities without ruining competition. Costs for WBGT equipment and immersion tubs are modest compared with the potential human and legal consequences of inaction. Where budgets are tight, regional athletic associations, school districts, or state health departments can pool resources to provide shared equipment and certified training.

Legal, reputational, and ethical stakes for institutions

When institutions fail to follow their own policies or to adopt widely accepted best practices, they expose themselves to legal and ethical consequences. Lawsuits following heat-related deaths and serious injuries have resulted in substantial settlements and criminal charges in extreme cases. The Massachusetts-based Korey Stringer Institute and other organizations have provided the framework that courts and juries increasingly treat as the standard of care.

Beyond legal risk, universities and school districts face reputational harm and internal morale damage. Athletes and families rightly expect institutions with responsibility for student welfare to uphold that duty. Institutions that publicly assert a commitment to safety but do not operationalize it invite scrutiny and backlash. That scrutiny can force systemic change — but only after preventable harm occurs.

Ethically, the stakes extend beyond one team. Heat safety intersects with equity. Smaller programs, rural districts, and volunteer-run leagues may lack resources. Left unchecked, disparities in policy adoption will translate into unequal protection for young athletes. Policy reform should therefore include funding mechanisms and technical assistance targeted to programs with limited means.

The broader public-health context: not just athletes at risk

The danger of extreme heat reaches beyond competitive sport. Marching bands, outdoor staff, event volunteers, construction workers, and school children all face similar physiological threats. The University of Iowa band member who collapsed and later died during an outdoor football game in 2026 illustrates that heat-related collapse can occur in non-athlete populations performing physical activity in the sun. Public institutions need broad heat-preparedness plans that cover all outdoor activities, not just athletics.

Approaches that protect athletes — WBGT monitoring, staged acclimatization, onsite cooling equipment, and training — are applicable to workplaces and community events. Cross-sector planning increases efficiency: municipal or institutional investment in WBGT monitoring and shared immersion facilities can serve multiple population groups. Public health departments should collaborate with education and athletics to disseminate best practices and support implementation.

What accountability looks like: investigations, reforms, and cultural change

Independent investigations that combine medical expertise, operational analysis, and public transparency are essential. They should answer whether policies were followed, whether equipment was available and functional, whether staff had authority to halt unsafe activity, and whether the emergency response met clinical standards for suspected exertional heat stroke.

Reform must follow from findings. That can include mandatory statewide standards, funding for necessary equipment, and enforcement mechanisms for noncompliance. Decision-making authority for weather-based cancellations or modifications must be explicit and vest power in qualified medical staff rather than in coaches or administrators who face competitive pressure.

Cultural change is harder but critical. Athletic cultures that valorize pushing through distress sow the conditions for tragedy. Teams must normalize early reporting of heat symptoms and remove any penalties — explicit or implicit — for pulling back. Coaches, parents, and administrators should recognize that competitiveness and safety are not mutually exclusive. The Georgia experience shows that careful, phased acclimatization and WBGT-based limits do not diminish play quality; they preserve athlete health.

Independent review at ASU and the limits of institutional self-examination

ASU’s appointment of former Arizona Supreme Court Chief Justice Scott Bales to lead a review of planning and response represents a formal step toward accountability. A credible review should have broad powers: access to all evidence, the ability to interview witnesses under confidentiality agreements, and the authority to recommend immediate operational changes and public reporting of findings.

Mayich’s family has asked for an even more expansive independent investigation that specifically addresses whether university, athletic conference, or NCAA rules were violated. That call underscores a common tension: internal reviews are constructive when they lead to rapid operational fixes, but victims and the public often demand independent inquiry to ensure impartiality and full transparency.

A meaningful review will also assess systemic issues — why required approvals were apparently absent, whether staff were trained and empowered to halt activity, and whether medical equipment and emergency protocols were properly supplied and rehearsed. If failures are identified, a swift plan for remediation — including interim safety measures — should be publicly posted and enforced.

Practical advice for athletes, parents, and coaches now

Until systems are uniformly strengthened, individuals and smaller programs must take practical steps to reduce risk.

• Require on-site WBGT measurements whenever activities occur outdoors in warm months. A basic WBGT meter is a modest investment and provides actionable data.
• Build acclimatization into all preseason planning. For transfers or students arriving from cooler climates, extend supervised, gradual outdoor exposure before full workloads.
• Ensure immediate access to cold-water immersion: an appropriate tub, sufficient ice, and trained staff. Know the location and operational plan at every practice and contest.
• Train coaches and volunteers to recognize early signs of exertional heat illness and to stop activities when players show distress. Empower athletic trainers to override coaching decisions on safety.
• Prioritize hydration and shade: structured, mandatory breaks, and easily accessible fluids.
• Advocate for clear written policies at the district, club, or state level that mandate equipment and protocols, not merely recommend them.
• For parents: ask what your child’s program does to measure heat stress and what emergency equipment and training are in place. Demand transparency and written policies.

These measures do not require high budgets; they require commitment and clear protocols.

What accountability and reform should look like at scale

National organizations should move from guidance to minimum standards. The NCAA could adopt enforceable mandates for WBGT monitoring, immersion access, and acclimatization schedules. State high school associations should mandate and audit compliance, offering financial or technical aid to programs that need equipment or staff.

Funding mechanisms matter. State education budgets, athletic associations, or federal grants targeted at school safety can subsidize WBGT systems and immersion equipment. Shared regional resources — mobile immersion units, for example — could serve multiple schools and lower per-program costs.

Training and certification programs for coaches and athletic staff should be standardized. Emergency action plans should be mandatory, and rehearsal of those plans should be documented. Finally, transparency — including public reporting of incidents and corrective action — will create accountability and encourage continuous improvement.

A final appraisal of risk, readiness, and responsibility

Heat-related illness is predictable, measurable, and preventable when evidence-based protocols are followed. The tools exist: WBGT monitoring, staged acclimatization, cold-water immersion, rectal thermometry for accurate diagnosis, and trained staff empowered to make safety-first decisions. The challenge is implementation. That challenge spans budgets and culture, legal frameworks and day-to-day decision-making.

The story of Matthew Mayich places a human face on these systemic shortcomings. It is a reminder that progress since Korey Stringer’s death is real, but incomplete. When policies are followed and equipment is at hand, athletes survive heat stroke. When protocols lapse, the consequences are catastrophic.

Institutions with control over young athletes — universities, school districts, leagues, and coaches — carry a clear duty to act. They must prioritize measurable safety over convenience or perceived competitive edge. Families, communities, and public-health officials should hold them to account. Every delay or equivocation risks repeating the same preventable harm.

FAQ

Q: What is exertional heat stroke and how does it differ from other heat illnesses? A: Exertional heat stroke is a medical emergency caused by intense physical activity that overwhelms the body’s ability to dissipate heat. It differs from heat exhaustion in severity: exertional heat stroke involves central nervous system dysfunction (confusion, collapse, seizures) and very high internal temperatures that can damage organs. Rapid cooling via cold-water immersion is the accepted lifesaving treatment.

Q: What are the earliest signs to watch for during practice? A: Early signs include dizziness, lightheadedness, headache, nausea or vomiting, weakness, disorientation, stumbling, and cessation of coordinated movement. Visible confusion, loss of consciousness, or seizures indicate advanced heat stroke and require immediate emergency response.

Q: Why is wet bulb globe temperature (WBGT) important? A: WBGT incorporates temperature, humidity, wind, sun exposure, and radiant heat — the factors that determine an athlete’s heat load. It is a better predictor of environmental stress than ambient temperature or heat index alone. On-field WBGT readings are necessary for accurate risk assessment and for making operational decisions about activity modification or cancellation.

Q: How quickly must a heat stroke victim be cooled? A: Cooling must begin immediately. Cold-water immersion reduces core temperature far faster than passive cooling methods. Clinical evidence shows immersion can often lower core temperature sufficiently within about 20–30 minutes, whereas cooling by air conditioning or iced towels takes far longer and may not prevent irreversible damage.

Q: Why are rectal thermometers used? A: Rectal thermometry provides the most accurate measurement of core body temperature in suspected exertional heat stroke. Oral or tympanic readings can underestimate core temperature due to peripheral vasoconstriction or environmental factors, which can delay diagnosis and appropriate treatment.

Q: Are there clear policies that athletic programs should adopt? A: Yes. Programs should require on-field WBGT monitoring with specified thresholds for activity modification, staged acclimatization periods for preseason activities, mandatory water and shade breaks, immediate access to cold-water immersion equipment, and trained staff empowered to halt activity. These should be mandatory, not advisory.

Q: How can smaller schools or volunteer programs afford equipment and training? A: Options include pooled regional resources, grants, district-level procurement, and partnerships with local medical providers or universities. WBGT meters and basic immersion setups are relatively low-cost compared to the human and legal costs of preventable tragedies. Associations and public-health agencies can help coordinate shared solutions.

Q: What should parents ask athletic programs? A: Ask whether on-field WBGT measurements are taken, how acclimatization is handled, whether immersion tubs and rectal thermometers are available, how staff are trained for heat emergencies, and whether emergency-action plans are rehearsed. Request written policies and documentation of training.

Q: What legal consequences can institutions face? A: Institutions can be held civilly liable for negligence if they fail to follow accepted standards of care, and in extreme cases criminal charges have been pursued. Settlements and judgments in past cases underscore the legal risk of failing to implement and enforce heat-safety protocols.

Q: How should institutions balance competitiveness with safety? A: Safety must take precedence. Evidence shows that structured acclimatization and WBGT-based activity limits do not undermine long-term competitiveness; they prevent catastrophic outcomes while preserving athlete readiness. Sustainable competitive performance depends on healthy athletes.

Q: What immediate actions should institutions take after an incident? A: Secure all relevant records, preserve evidence, initiate an independent, expert-led investigation with public reporting, implement interim safety measures pending the review (such as mandatory on-field WBGT monitoring and suspension of high-exertion outdoor activities during risky conditions), and communicate transparently with athletes, families, and staff about steps taken to ensure safety.

Q: Is climate change making this worse? A: Observational and attribution studies show that extreme heat events are increasing in frequency and intensity across many regions. Those changes increase the probability that athletes will encounter life-threatening heat conditions, making robust mitigation and adaptation measures more urgent.

Q: Can synthetic turf be made safer? A: Some mitigation is possible: lighter-colored turfs reflect more solar radiation, and watering can temporarily reduce surface temperatures (though not without trade-offs). The preferred approach is to use stricter WBGT thresholds when synthetic turf is in play, and to rethink turf choices and scheduling in high-heat climates.

Q: Who should enforce these measures? A: Enforcement is best accomplished through a combination of national bodies (e.g., NCAA, national federations) setting minimum standards, states and school associations mandating and auditing compliance, and local athletics directors ensuring day-to-day implementation. Independent oversight and public reporting reinforce adherence.

Q: Where can I find more information and guidance? A: Trusted sources include the Korey Stringer Institute, state high school associations with established heat policies, sport-medicine associations, and peer-reviewed literature on exertional heat stroke and WBGT practice. Local public-health departments can also provide guidance tailored to regional climate conditions.
