Sustained activity could provoke heatstroke.Heat index readings emphasize conditions of light breezes and shaded spots. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', blends air temperature and moisture content to represent the felt temperature to humans. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Children often overlook the need for breaks and fluid intake.
