Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', marries air temperature and humidity to produce a value illustrating perceived warmth. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
