Note: The heat index, also known as 'feels like' or 'real feel', provides an understanding of perceived warmth by combining temperature and relative humidity. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
