Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is the result of factoring in humidity to the air temperature, indicating perceived warmth. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. 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 largely significant for 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.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
