It is crucial to understand that heat index figures are for shade and gentle wind conditions. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', integrates the air's temperature and its humidity to showcase the felt temperature by people. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. 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.
