Chan School of Public Health. In fact, 54.5% of the students in the study had urine concentrations that qualified them as below their minimum daily water intake.” In fact, boys are less likely to drink enough fluid when compared with girls. And just an 8 fluid ounce daily increase in water intake was enough to significantly lower risk of inadequate hydration.

  • Generally, there is a minimum fluid intake set at 50 ounces on average per day for children ages 5-12.
  • If your child is an athlete or moves a lot, he may need up to 25% more water per day than the average child.
  • Sipping clean water throughout the day, averaging 3-4 ounces per hour in a 12 hour day is generally a good practice.
