Heat index

In December, the heat index is appraised at a blisteringly hot 41°C (105.8°F). Take special precautions - heat exhaustion and heat cramps are expected. Heatstroke may occur with lengthy activity.
Research indicates the heat index considers values in shaded locales and with 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 'real feel' or 'feels like', shows a temperature sensation when both heat and moisture conditions are combined. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
