Note: The heat index, also known as 'real feel' or 'feels like', determines the feeling of heat when you account for the relative humidity. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children commonly overlook the importance of rest and fluid replenishment. Thirst, being a delayed sign of dehydration, emphasizes the need to keep hydration up, especially during lengthy physical activities.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
