Note: The heat index, also known as 'real feel' or 'apparent temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. 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 quite important for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
