Note: The heat index, also known as 'real feel' or 'feels like', marries air temperature and humidity to produce a value illustrating perceived warmth. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
