How to Keep Kids Hydrated During Sports

Practical strategies for maintaining proper hydration before, during, and after youth sports activities.

1. Before Practice or Games. Start hydration well before sports begin. Many families find success having kids drink 16-20 ounces of water 2-3 hours before activity, then another 8 ounces 15-20 minutes before starting. This gives the body time to absorb fluids and allows for bathroom breaks before play begins. Make pre-hydration part of the routine. Some parents set reminders or pack water bottles with the sports gear as a visual cue. The goal is arriving at the field or court already well-hydrated, not trying to catch up once activity starts.
2. During Activity. Encourage frequent small sips rather than waiting for scheduled breaks. Research suggests kids should drink 3-8 ounces every 15-20 minutes during activity, depending on their size and the intensity of play. Cool water (50-59°F) is typically absorbed faster than room temperature fluids. For activities lasting longer than an hour, especially in hot weather, sports drinks containing electrolytes may be helpful. However, water remains the best choice for most youth sports sessions under an hour. Many pediatricians recommend avoiding energy drinks entirely for children and teens. Watch for signs that kids need more fluids: decreased energy, complaints of feeling tired, or less frequent urination during long tournaments or multi-game days.
3. After Sports. Post-activity hydration helps with recovery and prepares kids for their next practice or game. A general guideline is drinking 16-24 ounces of fluid for every pound lost through sweat, though most families don't weigh kids before and after sports. Practically, this often means continuing to drink water for several hours after activity ends. Foods with high water content like watermelon, oranges, or yogurt can contribute to rehydration while providing nutrients for recovery. Some families make post-game hydration social by bringing water bottles to share or stopping for a healthy snack that includes fluids.
4. Hot Weather Considerations. Heat significantly increases hydration needs. In temperatures above 80°F, kids may need 50% more fluids than usual. Look for shaded rest areas and encourage more frequent water breaks. Signs of heat-related dehydration include flushed skin, rapid heartbeat, nausea, or confusion. Many coaches and leagues have heat policies that mandate water breaks or modified play when temperatures reach certain thresholds. Light-colored, loose-fitting clothing helps kids stay cooler and may reduce fluid needs. Some families freeze water bottles partially the night before hot-weather games so kids have cool drinks throughout the activity.
5. Making Hydration Appealing. Plain water is ideal, but some kids resist drinking enough. Adding a splash of 100% fruit juice, sliced fruit, or cucumber can make water more appealing without adding excessive sugar. Let kids pick out their own water bottles or add fun elements like colorful straws or time markers on the bottle showing hydration goals throughout practice. Some families use apps that gamify water intake or set family hydration challenges. Avoid making hydration a power struggle. Focus on building habits and making it easy rather than forcing specific amounts at specific times.
