Note: The heat index, also known as 'feels like' or 'apparent temperature', is the outcome of merging air's temperature and its humidity metrics. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold particular significance for children. 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.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
