Note: The heat index, also known as 'felt air temperature' or 'real feel', is a single figure representing how weather conditions feel when combining temperature and humidity.

It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
