Weather in September

Continuous activity might result in heatstroke.Heat index specifics point out values are for conditions of shade and a slight breeze. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'feels like', blends air temperature and moisture content to represent the felt temperature to humans. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly important for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
