Note: The heat index, also known as 'feels like' or 'felt air temperature', is an estimation of the warmth sensation when considering humidity levels. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Children frequently do not understand the need for recuperation and hydration. Thirst, being a late manifestation of dehydration, underlines the need to hydrate frequently, especially when engaging in prolonged physical exercises.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
