December's average heat index is computed to be a tropical 30°C (86°F). Ongoing activity coupled with exposure often results in weariness and could induce heat cramps.It is emphasized that the heat index's values are meant for shaded zones with mild winds. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', integrates the air's temperature and its humidity to showcase the felt temperature by people. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are extremely significant for children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
