How to use:

  • • Enter your weight and select your typical activity level and environment
  • • Your recommendation accounts for sweat loss, climate, and physiological needs
  • • This is total fluid intake — coffee, tea, and food moisture count too (~20% of daily intake)
  • • Use the schedule to spread intake throughout the day rather than drinking all at once
  • • The best hydration signal: pale yellow urine means well hydrated
