Note: The heat index, also known as 'apparent temperature' or 'real feel', gives a temperature feeling by integrating air temperature and humidity. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
