Heat index

In September, the average heat index is estimated at a burning hot 46°C (114.8°F). Caution: Heat cramps along with heat exhaustion are expected. Sustained activity could lead to heatstroke.
Metrics for the heat index primarily focus on shaded spots and light wind conditions. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', represents the fusion of temperature and moisture in the air to suggest how warm it feels. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. 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.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
