Note: The heat index, also known as 'real feel' or 'felt air temperature', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to 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 cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
