Note: The heat index, also known as 'real feel' or 'apparent temperature', is a measure of how hot it feels when the actual air humidity is factored in. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Children frequently do not comprehend the need for rest and hydration. Thirst is an advanced stage of dehydration - staying hydrated, especially during extended physical exercises, is essential.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
