Take into consideration that the heat index values are calculated for shade and light wind conditions. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', combines air temperature and relative humidity to represent a human perceived temperature equivalent. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. When the body's heat gain surpasses its removal capacity, body temperature starts to climb, leading to potential heat-related ailments.
