Note: The heat index, also known as 'feels like' or 'apparent temperature', marries air temperature and humidity to produce a value illustrating perceived warmth.

Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly critical to babies and toddlers. Children often overlook the necessity for resting and fluid replenishment. Thirst is a late sign of dehydration - thus, it is critical to stay hydrated, especially during extended periods of physical activities.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
