The Science

Studies suggest that a large portion of adults fail to maintain optimal hydration, with mild dehydration affecting an estimated 50–75% of Americans at any given time.

  • Caffeine, alcohol, and high-sodium diets can accelerate fluid loss, while sugary drinks often worsen dehydration by impairing fluid absorption.

  • Even mild dehydration can reduce endurance, focus, and cognitive performance, especially during outdoor activity or heat exposure.

Golf Performance when Dehydrated...

Everyone knows dehydration is bad. But how bad is it for your golf game? Hack city bad.

4 Excess Strokes

Research shows that even mild dehydration — just 1–2% body weight loss — reduces focus, reaction speed, and decision-making accuracy.


Collegiate golfers who were dehydrated took an average of four more strokes per 18-hole round, underscoring how mental fatigue and slower reaction times can translate directly to higher scores.
