Heat index

The heat index in December is computed to be a very hot 35°C (95°F). Exercise heightened safety, heat cramps and heat exhaustion are probable. Persistent activity may provoke heatstroke.
Understanding the heat index involves considering values for shaded locales with light wind. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a numerical representation of warmth when taking temperature and moisture levels into account. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Rising body temperatures due to excess heat retention could signify impending heat disorders.
