August's heat index is estimated at a fiery hot 100.4°F (38°C). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.Be aware that heat index ratings are designed for shaded locations and minor breezes. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly relevant to children. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
