Note: The heat index, also known as 'real feel' or 'feels like', reflects the blend of air temperature and relative humidity to give a temperature impression. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather.

Heat index values hold particular significance for children. Young ones often ignore the need to take a break and drink fluids. Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat.

Rising body temperatures due to excess heat retention could signify impending heat disorders.
