Note: The heat index, also known as 'apparent temperature' or 'feels like', is a numerical representation of warmth when taking temperature and moisture levels into account. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important 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.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
