Heat index

For most parts of August, the heat index is computed to be a burning hot 113°F (45°C). Be alert: Heat exhaustion along with heat cramps are probable. Heatstroke is a threat with sustained physical activity.
Heat index's context suggests values are appropriate for shady areas and slight breezes. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is a numerical representation of warmth when taking temperature and moisture levels into account. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
