Note: The heat index, also known as 'feels like' or 'real feel', reflects the blend of air temperature and relative humidity to give a temperature impression.

When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to 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.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
