Note: The heat index, also known as 'feels like' or 'real feel', is a value derived by merging air temperature with the humidity to convey how the climate feels. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. 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. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
