Heat index

For December, the heat index is computed to be a torrid 35°C (95°F). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.
Evaluating the heat index requires understanding its values in the shade and with gentle winds. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', joins air temperature with relative humidity to produce a temperature perception for humans. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.

Stand by precautions and apply sun safety measures. Evading sunburn is of great importance. 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. Consider a wide-brim hat essential for effective sun defense covering your face, neck, and eyes.
