Note: The heat index, also known as 'apparent temperature' or 'real feel', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
