Peer-reviewed studies and clinical findings on hydration, electrolytes, and cognitive performance — curated for athletes, coaches, and the curious.
How three nutrients work together to sharpen your mind — a review of the mechanisms, the evidence, and what the science actually says. Includes key takeaways for athletes, coaches, and parents.
The American College of Sports Medicine (ACSM) recommends beginning exercise in a well-hydrated state with normal electrolyte levels. According to its Position Stand on Exercise and Fluid Replacement, athletes should begin drinking fluids several hours before activity when appropriate. This allows the body time to absorb fluids and return to normal hydration before training or competition.
The ACSM also emphasizes that hydration needs vary depending on:
Rather than using a one-size-fits-all approach, hydration plans should be individualized.
Waiting until you feel thirsty during practice is often too late.
Developing a hydration routine before workouts helps athletes begin training better prepared, especially during hot weather or high-intensity sessions.
Acuity is designed to be part of an athlete's hydration routine before, during, and after training.
Its purpose is to support athletes who are working to stay hydrated throughout demanding workouts and competition.
Important Note: The ACSM study did not evaluate Acuity. The research supports hydration practices during exercise and provides scientific context for hydration planning.
The National Athletic Trainers' Association (NATA) recommends individualized hydration plans rather than a single recommendation for every athlete. Factors such as body size, sweat rate, exercise intensity, clothing, environment, and sport all influence fluid needs.
The position statement encourages coaches and athletes to:
Two athletes running the same workout on the same day may lose very different amounts of fluid through sweat.
Individual planning helps athletes develop consistent hydration habits throughout the season.
Acuity is intended to complement an athlete's overall hydration plan.
Whether preparing for practice, competing in tournaments, or training in hot conditions, athletes benefit from consistent hydration habits tailored to their own needs.
Important Note: These recommendations come from NATA's evidence-based position statement. The research did not test Acuity directly.
Hydration is important for more than physical performance.
Multiple studies have examined how hydration status relates to attention, reaction time, short-term memory, and mood. Research suggests dehydration may negatively affect certain aspects of cognitive performance, while rehydration has been associated with improvements in attention and reductions in fatigue in some settings.
Researchers continue to study these relationships, and results vary depending on the population, level of dehydration, and testing methods.
Athletes rely on more than strength and speed.
They also depend on:
Acuity is designed for athletes who want a hydration product as part of their training and competition routine.
Proper hydration is one factor that supports athletes during both physical and mental demands.
Important Note: The studies referenced examined hydration and cognitive performance. They did not evaluate Acuity or establish that Acuity produces these effects.
