The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion.

Heat index values hold particular significance for children. 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.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
