Note: The heat index, also known as 'real feel' or 'apparent temperature', integrates the air's temperature and its humidity to showcase the felt temperature by people. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Direct sun rays can make one feel hotter, potentially raising the heat index by 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 body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. 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. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
