Note: The heat index, also known as 'real feel' or 'felt air temperature', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. 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 remain especially vital for babies and toddlers. Children frequently do not understand the need for recuperation and hydration. Thirst, being a late manifestation of dehydration, underlines the need to hydrate frequently, especially when engaging in prolonged physical exercises.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. Rising body temperatures due to excess heat retention could signify impending heat disorders.
