December's mean heat index is estimated at a fiery hot 37°C (98.6°F). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.The standards for the heat index are set for locations in shade and under light breezes. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'feels like' or 'felt air temperature', joins air temperature with relative humidity to produce a temperature perception for humans. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
