Heat index

For September, the heat index is evaluated at a scorching 43°C (109.4°F). Keep alert: Heat cramps and heat exhaustion are probable. Heatstroke is a potential danger with continued physical activity.
Understand that the heat index values take into account shaded locations and mild winds. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', quantifies the warmth felt when relative humidity is considered. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
