Note: The heat index, also known as 'real feel' or 'felt air temperature', comes about by integrating the temperature readings with the humidity levels. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial 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.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. When the body's heat gain surpasses its removal capacity, body temperature starts to climb, leading to potential heat-related ailments.
