Note: The heat index, also known as 'real feel' or 'feels like', provides an understanding of perceived warmth by combining temperature and relative humidity.

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 primarily vital for children. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.
