Note: The heat index, also known as 'felt air temperature' or 'feels like', integrates the air's temperature and its humidity to showcase the felt temperature by people. 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. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
