Note: The heat index, also known as 'real feel' or 'feels like', is a value derived by merging air temperature with the humidity to convey how the climate feels. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
