Note: The heat index, also known as 'feels like' or 'real feel', is a metric representing the sensation of warmth when air temperature and moisture come together.

Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.
