Note: The heat index, also known as 'real feel' or 'felt air temperature', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
