Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', melds the effects of warmth and moisture to generate a feeling of heat. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Children often overlook the necessity for resting and fluid replenishment. Thirst is a late sign of dehydration - thus, it is critical to stay hydrated, especially during extended periods of physical activities.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
