Note: The heat index, also known as 'apparent temperature' or 'feels like', is a composite of temperature and humidity figures to convey how warm it feels. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.
