Staying Hydrated: How Much Water Youth Athletes Actually Need

Even mild dehydration — just 2% loss of body weight in fluids — can significantly impair performance, reduce reaction time, and increase injury risk. Most youth athletes show up to practice already dehydrated.

How Much Is Enough?

Baseline: half your body weight in ounces per day. A 140-pound athlete needs roughly 70 oz daily — more on training days, in heat, or during games.

Competition days: 16–20 oz two hours before, 8–10 oz fifteen minutes before, 6–8 oz every 15–20 minutes during activity.

Signs of Dehydration

Dark yellow urine. Headache, fatigue, muscle cramps, dizziness, difficulty concentrating. By the time you feel thirsty, you're already mildly dehydrated.

Water vs. Sports Drinks

Under an hour of exercise: water is sufficient. Longer sessions in heat: sports drinks replace lost electrolytes. Avoid energy drinks entirely — they're dangerous for youth athletes.

Build the Habit

Carry a water bottle everywhere. Drink with every meal. Pale yellow urine means you're on track.
