Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it.

Overheating and potential dehydration arise when body heat gain eclipses its release capability.
