Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values hold particular importance for children. 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 temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat.

When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
