Note: The heat index, also known as 'feels like' or 'apparent temperature', determines the feeling of heat when you account for the relative humidity. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. 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 particularly relevant to children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
