Prolonged activity may result in heatstroke.Remember that heat index calculations are made for conditions in the shade with light wind. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Children often overlook the necessity for resting and fluid replenishment.
