Heat index

The heat index value during August is evaluated at a blazing hot 113°F (45°C). Stay on guard: Heat exhaustion and heat cramps are predicted. Ongoing effort can cause heatstroke.
It is important to note that the heat index values are for shaded areas and light wind scenarios. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', arises from combining readings of air temperature and relative moisture content. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for 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.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
