The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'real feel' or 'feels like', joins air temperature with relative humidity to produce a temperature perception for humans. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of 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 are highly important for children. Children frequently do not understand the need for recuperation and hydration. Thirst, being a late manifestation of dehydration, underlines the need to hydrate frequently, especially when engaging in prolonged physical exercises.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
