Prolonged activity might induce heatstroke.Keep in mind the heat index values are meant for areas in shade and with light wind. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', reflects the feeling of heat when considering both air temperature and humidity. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees.
