The average heat index in December is estimated at an extremely hot 41°C (105.8°F). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.It is essential to grasp that the heat index's numbers are for shade and light wind settings. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
