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.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate.
