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 individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. 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 are extremely vital to babies and toddlers. Children commonly overlook the importance of rest and fluid replenishment. Thirst, being a delayed sign of dehydration, emphasizes the need to keep hydration up, especially during lengthy physical activities.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
