Coach and teacher heat hydration guide
Adults need a plan too
Coaches and teachers often focus on kids and forget their own fluid plan, especially during tournaments, field days, recess duty, and outdoor practices.
A personal bottle target plus scheduled group breaks helps adults model the behavior they want students or athletes to follow.
Group safety first
Use heat policies, shade, cooling, and rest breaks. Hydration alone cannot make unsafe heat safe.
Children and teens need age-specific guidance. This site's calculator is for adults, so youth hydration should follow school, sport, pediatric, or clinician guidance.
Frequently asked
Should coaches make athletes drink at every break?
Breaks should make water available and normalized, but forced overdrinking is not the goal. Youth guidance should come from sport and pediatric policies.
What should teachers do on hot field days?
Plan shade, water access, cooling breaks, activity changes, and symptom escalation before the event starts.
