Note: The heat index, also known as 'real feel' or 'apparent temperature', comes about by integrating the temperature readings with the humidity levels. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. 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.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
