In September, the heat index is evaluated at a blistering 43°C (109.4°F). Be prepared: Heat cramps and heat exhaustion are probable. Continued activity may lead to heatstroke.In terms of the heat index, values are set with light wind and shade conditions in mind. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
