Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. 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.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
