Note: The heat index, also known as 'real feel' or 'apparent temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young ones regularly neglect the requirement for rest and fluid replenishment. Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.
