Youngsters frequently overlook the need for breaks and fluid intake. Thirst is an advanced sign of dehydration - thereby highlighting the importance of keeping hydrated, particularly during long physical activities.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
