Heat index

For most parts of December, the heat index is appraised at a very hot 36°C (96.8°F). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.
Heat index's context suggests values are appropriate for shady areas and slight breezes. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is achieved by amalgamating air temperature with the relative humidity readings. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are especially vital to children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.

Persist with safeguards and heed sun safety doctrines. Keeping sunburn at bay is of prime importance. Minimize exposure to direct sunlight and seek shade from 10 a.m. to 4 p.m., when UV radiation is most intense, but remember that shade structures may not offer complete protection. Loose clothes with a tight weave are optimal for safeguarding yourself against the Sun's rays.
