Hydration and Electrolytes

Water as default

Hydration and Electrolytes

Hydration supports daily function, digestion, temperature regulation, exercise performance, and comfort. Needs vary with body size, heat, sweat, medications, kidney or heart conditions, and activity level.

Practical Rules

  • Use water as the default drink.
  • Increase fluids during heat, sweat, illness, travel, and high activity.
  • Do not force excessive water; overhydration can be dangerous.
  • Electrolytes may help during long/hot sweat sessions but are not magic.
  • People with kidney, heart, blood pressure, or fluid-restriction issues should follow medical guidance.
