Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. When there is abundant moisture in the air, the body's cooling through the evaporation process becomes less effective, leading to the sensation of overheating. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.
