Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', gives an indication of how one might feel in terms of heat after considering humidity. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly relevant to babies and toddlers. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
