Heat index values are highly important for children. Kids often lack the knowledge about the necessity to take breaks and consume liquids. Thirst, as a late symptom of dehydration, necessitates the maintenance of hydration, particularly during enduring physical activities.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat.

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