Note: The heat index, also known as 'felt air temperature' or 'real feel', is a numerical representation of warmth when taking temperature and moisture levels into account. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. 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 extremely vital to babies and toddlers. Young ones often ignore the need to take a break and drink fluids. Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
