Note: The heat index, also known as 'apparent temperature' or 'real feel', is the result of factoring in humidity to the air temperature, indicating perceived warmth. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
