Note: The heat index, also known as 'real feel' or 'felt air temperature', marries air temperature and humidity to produce a value illustrating perceived warmth. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant 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 human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.
