Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
