Heat index

For October, the heat index is estimated at a life-threatening hot 52°C (125.6°F). Take caution: Heat exhaustion and heat cramps are probable. Heatstroke may be imminent with ongoing effort.
Realize that the values for the heat index are set for shaded places and light winds. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a measure of how hot it feels when the actual air humidity is factored in. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. 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 are extremely significant for babies and toddlers. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

Clothes that are both tight-knit and comfortably loose are prime choices for sun protection.
