Heat index

In August, the heat index is computed to be a blazing hot 45°C (113°F). Keep guard: Heat cramps and heat exhaustion are likely. Continued activity increases the risk of heatstroke.
Keep in mind the heat index values are meant for areas in shade and with light wind. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', arises from combining readings of air temperature and relative moisture content. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.

Sun protection is enhanced with clothing that boasts a tight weave yet offers a loose fit.
