Note: The heat index, also known as 'real feel' or 'apparent temperature', offers an insight into how hot it feels when we factor in moisture content. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
