Sustained activity might cause heatstroke.It is worth noting that heat index values are gauged for conditions in the shade and light breezes.

Note: The heat index, also known as 'real feel' or 'feels like', quantifies the warmth felt when relative humidity is considered. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing.

Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
