Heat index

During December, the heat index is evaluated at a very hot 36°C (96.8°F). Ensure heightened precautions, risk of heat cramps and heat exhaustion is significant. Sustained activity could provoke heatstroke.
It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is found by incorporating humidity levels into the air temperature measurement. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold particular importance for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
