Heat index

December's heat index is computed to be a very hot 35°C (95°F). Take more preventive steps, risk of heat exhaustion and heat cramps is elevated. Long activity may culminate in heatstroke.
The metrics for the heat index are tailored for both shady environments and light winds. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', joins air temperature with relative humidity to produce a temperature perception for humans. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young ones often ignore the need to take a break and drink fluids. Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
