Note: The heat index, also known as 'apparent temperature' or 'feels like', is an estimation of the warmth sensation when considering humidity levels. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are essentially critical for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
