Exhaustion becomes probable with enduring exposure and activity, potentially causing heat cramps.It is important to note that the heat index values are for shaded areas and light wind scenarios. 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 'real feel' or 'apparent temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children.

Thirst is a delayed symptom of dehydration - hence, it is vital to maintain hydration, particularly during ongoing physical activities.
