Heat index

During September, the heat index is computed to be an extremely hot 43°C (109.4°F). Notice: Heat cramps and heat exhaustion are likely. Continued strenuous activity might lead to heatstroke.
It is emphasized that the heat index's values are meant for shaded zones with mild winds. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', evaluates the perceived heat by adding the effect of moisture in the air. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
