Heat index

In December, the heat index is computed to be a very hot 37°C (98.6°F). Adopt enhanced safety measures, heat exhaustion and heat cramps could occur. Continuous activity may induce heatstroke.
Take note of the fact that heat index values are based on shaded circumstances with light airflows. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.

A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes.
