Heat index values hold particular significance for children. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration.
