Note: The heat index, also known as 'feels like' or 'real feel', embodies the combination of air temperature and moisture content to illustrate perceived heat. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. 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. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
