For most parts of December, the heat index is evaluated at a tropical 34°C (93.2°F). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.Records show heat index calculations are tailored for shaded regions and mild winds. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'real feel' or 'feels like', is a measure of how hot it feels when the actual air humidity is factored in. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. 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 particularly relevant to children. 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.
