Heat index

The heat index value during December is estimated at a torrid 38°C (100.4°F). Exercise enhanced safety steps, heat cramps and heat exhaustion are probable. Heatstroke could be a result of sustained activity.
The metrics for the heat index are tailored for both shady environments and light winds. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
