Note: The heat index, also known as 'real feel' or 'apparent temperature', is the outcome of merging air's temperature and its humidity metrics. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
