Note: The heat index, also known as 'apparent temperature' or 'feels like', determines the feeling of heat when you account for the relative humidity. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Kids often lack the knowledge about the necessity to take breaks and consume liquids. Thirst, as a late symptom of dehydration, necessitates the maintenance of hydration, particularly during enduring physical activities.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
