The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity.

Heat index values remain especially vital for babies and toddlers. Children commonly overlook the importance of rest and fluid replenishment. Thirst, being a delayed sign of dehydration, emphasizes the need to keep hydration up, especially during lengthy physical activities.
