Note: The heat index, also known as 'felt air temperature' or 'feels like', gives a temperature feeling by integrating air temperature and humidity. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young ones often do not realize the necessity to rest and replenish their fluids. Thirst is a delayed indication of dehydration - keeping hydrated, particularly in prolonged physical activity, is crucial.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
