Note: The heat index, also known as 'felt air temperature' or 'feels like', determines the feeling of heat when you account for the relative humidity. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
