Heat index

For January, the heat index is evaluated at a scorching 41°C (105.8°F). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.
Observations indicate that the heat index values are for shady locations with light wind. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', arises from combining readings of air temperature and relative moisture content. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
