Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', represents the fusion of temperature and moisture in the air to suggest how warm it feels. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
