Note: The heat index, also known as 'apparent temperature' or 'real feel', blends air temperature and moisture content to represent the felt temperature to humans. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.
