The average heat index in December is evaluated at a torrid 37°C (98.6°F). Implement additional preventive actions, heat cramps and heat exhaustion are potential hazards. Heatstroke could follow prolonged activity.In reference to the heat index, it's for places in shade and with a slight wind. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', integrates the air's temperature and its humidity to showcase the felt temperature by people. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values hold particular importance for children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

A UV Index reading of 6 to 7 represents a high health vulnerability from unprotected exposure to Sun's UV rays for average individuals.Note: A maximum high daily UV index of 7 during December translates into the following directions:
Escape overexposure. People with light skin may incur burns in fewer than 20 minutes. Attempt to stay under shade and limit exposure to the Sun between 10 a.m. and 4 p.m., when UV radiation is at its peak. Remember, devices such as parasols or canopies might not provide complete sun protection. Employ a wide-brim hat for potent defense against up to 50% of UV rays.
