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.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
