Note: The heat index, also known as 'real feel' or 'apparent temperature', provides an understanding of perceived warmth by combining temperature and relative humidity. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
