Note: The heat index, also known as 'apparent temperature' or 'real feel', gauges the sensation of temperature factoring in the air's moisture content. 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. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
