Note: The heat index, also known as 'apparent temperature' or 'feels like', melds the effects of warmth and moisture to generate a feeling of heat. 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 are extremely vital to babies and toddlers. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
