Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Children often overlook the necessity for resting and fluid replenishment. Thirst is a late sign of dehydration - thus, it is critical to stay hydrated, especially during extended periods of physical activities.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down.

Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
