Excessive heat exposure in the workplace poses serious risks to health, safety, and productivity. Workers often begin shifts dehydrated, increasing the risk of heat-related illnesses and acute kidney injury. Evidence supports hydration programs and low-cost cooling methods like shade, fans, and cooling gear to reduce physiological strain and improve performance. Tailored, sustainable solutions are essential, especially for vulnerable populations. Employers must prioritize access to fluids, rest, and cooling to protect worker health in a warming world.

Occupational heat exposure poses serious risks to worker health, safety, and productivity. Unlike athletes, workers often face prolonged heat stress with limited rest, hydration, and medical support. This can lead to acute conditions like heat exhaustion and exertional heat stroke, and chronic issues such as kidney disease of nontraditional origin (CKDnt). Vulnerable populations—especially young male laborers in low-income countries—are disproportionately affected. Heat stress also reduces work capacity, increases accidents, and drives significant economic losses. Understanding these impacts is essential to developing effective, evidence-based heat mitigation strategies to protect workers in an increasingly warmer world.

Spinal cord injuries (SCI) are often caused by trauma or congenital disorders, leading to varying degrees of motor, sensory and autonomic function loss. The extent of these losses depends on the lesion level and completeness which also influences the autonomic nervous system function that is essential for understanding altered cardiovascular and respiratory responses to exercise. Athletes with SCI face heightened thermoregulatory challenges due to a reduction in afferent input to and efferent control of the thermoregulatory system, making these athletes more susceptible to heat illness. Consequently, managing heat stress in athletes with SCI is crucial for their safety and performance during sports.

Athletes with sickle cell trait deserve special attention to optimize performance and prevent a medical emergency due to the complex nature of the condition. Sickle cell trait is considered benign at rest yet dangerous during exercise. During exertional activities, athletes with sickle cell trait have a reduced oxygen carrying capacity, possibly leading to lactic acid buildup causing red blood cells to sickle. The practitioner should implement pre-calculated work-to-rest ratios or allow athletes to self-pace. Low atmospheric pressure at high altitudes lowers oxygen saturation levels, increasing the risk of red blood cells sickling. If travel to high-altitude areas is necessary for athletes with sickle cell trait, stakeholders (including coaching staff) will need to be educated on the risks, modify activities and set restrictions based on symptoms. Exercising in warm to hot environments raises core body temperature, potentially causing red blood cells to sickle as warmed blood moves from the core of the body to the working muscles. Practitioners should monitor environmental conditions using wet bulb globe temperature and modify activities based on established heat risk zones along with the utilization of heat acclimatization guidelines to promote beneficial adaptations.

Physically demanding occupations (PDO) require high levels of energy expenditure and technical skill to complete day-to-day tasks and training. Workers in PDO are at a greater risk for heat strain/illness compared to other occupations worldwide. While research for nutrition requirements for PDO is somewhat limited, there is evidence that the current daily caloric intake habits of some workers may only account for half of their daily energy expenditure. The authors review the physiological and metabolic demands of the tasks encompassed in PDO and the current guidelines for proper hydration and nutrition for these various professions.

Athletes’ use of supplements is highly prevalent across sport and competitive levels. High prevalence is combined with indiscriminate use. This remains a concern in sport as it can lead to negative health effects and the risk of committing an anti-doping rule violation. Consequences of committing an anti-doping rule violation through supplement use are significant for competitive athletes due to the principle of strict liability. The principle of strict liability interacts with a growing and professionally marketed industry that is poorly regulated. Consequently, competitive athletes can find themselves in a vulnerable and risky position when it comes to consuming supplements. Dr Susan Backhouse discusses adopting a behavioral approach and adherence to RMSUG to help identify what needs to change to protect athletes from unintentionally doping through indiscriminate supplement use.

Daily hydration management for a youth athlete extends beyond just sport performance to also facilitating academic achievement and overall health. Establishing sensible hydration behaviors as a youth athlete can be instrumental in underpinning healthy hydration habits as an adult that enable wellness and help to maintain long-term health. As youth develop and advance through sport, they need to develop personal initiative and autonomy to make healthy and ethical decisions about their involvement in sport, including managing their own hydration needs and strategies. Dr Michael Bergeron discusses contemporary approaches utilizing multi-domain, complex systems, and state-of-the-art tools and methods instrumental in fully recognizing the wide-ranging role and contribution of hydration to youth athletes’ health and sustainable sport participation and performance.

Substantial volumes of fluid can be lost during intense or prolonged exercise as a consequence of thermoregulatory sweating. In these situations, athletes need to drink during and after exercise to replace fluids lost to avoid potential negative effects of dehydration. Fluid replacement is a multi-step process involving a number of physiological systems including fluid intake, fluid delivery to the bloodstream, distribution within the body fluid compartments, and whole-body fluid retention. Adequate fluid replacement is influenced by beverage composition, as certain ingredients can facilitate or hinder one or more steps in the rehydration process. Dr Lindsay Baker reviews the scientific principles of fluid replacement and role of beverage formulation on the rehydration process for athletes.
