Note: The heat index, also known as 'real feel' or 'apparent temperature', measures the perceived warmth when incorporating the humidity present in the air. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance 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.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
