Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.

As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
