Sustaining activity may result in heat cramps.From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', shows a temperature sensation when both heat and moisture conditions are combined.
