Heat index

Throughout December, the heat index is evaluated at a fiery hot 37°C (98.6°F). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.
Factoring in the heat index, values are geared towards shaded areas with light breezes. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'real feel' or 'feels like', takes into account both air temperature and humidity to illustrate what people actually feel. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are especially vital 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.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

Sidestep overexposure. Individuals with fair complexions risk burning in fewer than 20 minutes. To the best of your ability, limit your exposure to the sun between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. Consider a wide-brim hat essential for effective sun defense covering your face, neck, and eyes.
