Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is the outcome of merging air's temperature and its humidity metrics. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
