Heat index's context suggests values are appropriate for shady areas and slight breezes. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is found by incorporating humidity levels into the air temperature measurement. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children frequently do not comprehend the need for rest and hydration. Thirst is an advanced stage of dehydration - staying hydrated, especially during extended physical exercises, is essential.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. 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. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
