A sense of exhaustion might occur with extended exposure and activity, potentially causing heat cramps.Be aware that heat index ratings are designed for shaded locations and minor breezes. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is the result of factoring in humidity to the air temperature, indicating perceived warmth. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly important for children. Children frequently underestimate the importance of resting and drinking fluids.
