Note: The heat index, also known as 'apparent temperature' or 'feels like', is an aggregate value of air's warmth and moisture to show the human-felt temperature. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. 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 hold particular importance 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.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. With excessive moisture in the atmosphere, the effectiveness of the evaporation process is decreased, causing the body to cool down less efficiently, leading to a sensation of overheating. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
