Heat index

During December, the heat index is estimated at a torrid 38°C (100.4°F). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.
Metrics for the heat index primarily focus on shaded spots and light wind conditions. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'feels like', measures the perceived warmth when incorporating the humidity present in the air. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance 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 combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.

Take precautions against overexposure. Protection against sun damage is needed. Minimize exposure to direct sunlight and seek shade from 10 a.m. to 4 p.m., when UV radiation is most intense, but remember that shade structures may not offer complete protection. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes.
