Heat index

The heat index value for August is appraised at a life-threatening hot 47°C (116.6°F). Beware: Heat exhaustion along with heat cramps are on the cards. Heatstroke could result from sustained physical activity.
Always consider that heat index estimations are for light winds and places in the shade. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', measures the perceived warmth when incorporating the humidity present in the air. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
