Heat index

In December, the heat index is estimated at a blistering 41°C (105.8°F). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.
Heat index data is primarily for areas with shade and subjected to light winds. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'feels like' or 'real feel', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
