Heat index

In December, the heat index is computed to be a sweltering 37°C (98.6°F). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.
Heat index specifics point out values are for conditions of shade and a slight breeze. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', binds temperature metrics with humidity values to give a sense of the actual warmth. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.

It's wise to wear UVA and UVB-blocking sunglasses when the sun shines brightly.
