Heat index

In August, the average heat index is calculated to be a scorching 111.2°F (44°C). Keep guard: Heat cramps and heat exhaustion are likely. Continued activity increases the risk of heatstroke.
Always consider that heat index estimations are for light winds and places in the shade. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', offers an insight into how hot it feels when we factor in moisture content. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
