Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', determines the feeling of heat when you account for the relative humidity.

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 are particularly important for children. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.
