Note: The heat index, also known as 'apparent temperature' or 'feels like', is a value derived by merging air temperature with the humidity to convey how the climate feels. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. 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 of high significance for children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
