Note: The heat index, also known as 'apparent temperature' or 'real feel', reflects the feeling of heat when considering both air temperature and humidity. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, 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 highly critical to babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
