Note: The heat index, also known as 'apparent temperature' or 'real feel', gauges the sensation of temperature factoring in the air's moisture content. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children often overlook the necessity for resting and fluid replenishment. Thirst is a late sign of dehydration - thus, it is critical to stay hydrated, especially during extended periods of physical activities.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. 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. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
