Note: The heat index, also known as 'real feel' or 'feels like', gauges the sensation of temperature factoring in the air's moisture content. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of 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. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
