Note: The heat index, also known as 'feels like' or 'apparent temperature', comes about by integrating the temperature readings with the humidity levels. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. 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 underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
