Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is the result of factoring in humidity to the air temperature, indicating perceived warmth. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Juveniles often do not understand the need to recuperate and rehydrate. Thirst is a delayed symptom of dehydration - hence, it is vital to maintain hydration, particularly during ongoing physical activities.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
