Note: The heat index, also known as 'feels like' or 'real feel', evaluates the perceived heat by adding the effect of moisture in the air. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
