Note: The heat index, also known as 'apparent temperature' or 'feels like', embodies the combination of air temperature and moisture content to illustrate perceived heat. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are essentially critical for children. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
