HEAT STRESS
Preventative Hydration Protocols for Heat Stress Management:
Applications from Sport Science
Personalized hydration protocols, informed by sports science, are essential for preventing
heat stress and ensuring the safety and performance of industrial workers exposed to
extreme heat.

Imagine running 135 miles in California’s Death Valley, with temperatures soaring to 130 degrees Fahrenheit under the blazing sun, while maintaining a pace of 10 kilometers per hour. Elite athletes tackle this challenge in the Badwater Ultramarathon
in under 22 hours. What crucial lessons can industrial workers draw from these extraordinary athletes to perform safely and efficiently in similarly extreme conditions?
Proper hydration is key. While heat acclimation is crucial, de- hydration can negate its benefits, underscoring the need for effec- tive hydration strategies to ensure worker safety and performance.
As the climate crisis escalates, industrial workers are on the frontlines, battling extreme heat that jeopardizes their health and productivity. Like athletes, industrial athletes are exposed to high temperatures and demanding physical work and are particularly vulnerable to heat stress. Thirty-five percent of American PDO workers experience occupational heat strain1, significantly impact- ing productivity and health.
In this challenging landscape, proper hydration emerges as a critical defense. The Occupational Safety and Health Administra-
tion (OSHA) calls out hydration as key to heat illness prevention in its recent bulletin2, but one-size-fits-all guidelines fall short. Enter the realm of sports science, where personalized hydration strategies and advanced monitoring technologies offer promising solutions for heat stress management in industrial settings.
The National Institute for Occupational Safety and Health (NIOSH) recommends that workers consume one cup (8 oz or 250 mL) of water every 15-20 minutes3. Robust individual variability exists in exercise-related fluid losses. So workers should consider individual needs based on environmental conditions, work inten- sity and heat exposure duration.
Personalized Hydration Protocols
Personalized hydration protocols, informed by sports science, pro- vide a tailored approach to combat heat stress. Athletes use individu- alized hydration strategies to optimize performance and prevent heat- related illnesses. Sports science has long recognized the importance of tailored hydration, which can significantly enhance safety and per- formance. Maintaining hydration status with minimal variation (+1
