Heat index

In December, the average heat index is computed to be a blisteringly hot 41°C (105.8°F). Undertake additional precautions, heat cramps and heat exhaustion could happen. Heatstroke could occur from sustained activity.
Heat index readings emphasize conditions of light breezes and shaded spots. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. Rising body temperatures due to excess heat retention could signify impending heat disorders.

Safeguard your eyes, ears, and face from sun rays with the aid of a wide-brim hat.
