Hydration for Fighters: The Performance Variable You Ignore
A 2% drop in hydration measurably slows reaction time and power. For a fighter, that's the margin between winning and losing.

Fighters obsess over food and forget water — yet hydration may swing performance more than any single meal.
Why it matters Even mild dehydration measurably reduces reaction time, power output, focus and the brain's resilience to shots. For a fighter, those are the exact margins that decide rounds.
Hydrate like a pro - Daily baseline — consistent water through the day, not a panic chug before training. - Electrolytes — sodium and minerals, especially around hard, sweaty sessions. - Respect the cut — aggressive dehydration to make weight is the most dangerous, performance-killing form of all.
You can't be sharp and dehydrated at the same time.
Manage water like the performance variable it is, and everything else works better.
