Note: The heat index, also known as 'feels like' or 'felt air temperature', is a single figure representing how weather conditions feel when combining temperature and humidity. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of 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. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
