Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat.

Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
