Note: The heat index, also known as 'felt air temperature' or 'feels like', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
