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. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
