Note: The heat index, also known as 'felt air temperature' or 'real feel', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. 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 particularly important for children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
