Long-term activity may precipitate heatstroke.It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', combines air temperature and relative humidity to represent a human perceived temperature equivalent. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
