Note: The heat index, also known as 'feels like' or 'real feel', takes into account both air temperature and humidity to illustrate what people actually feel. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
