Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat.
