Heat index

The average heat index in October is evaluated at an extremely hot 43°C (109.4°F). Mind: Heat cramps along with heat exhaustion are anticipated. Heatstroke can develop with continued physical activity.
It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', blends air temperature and moisture content to represent the felt temperature to humans. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
