Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', arises from combining readings of air temperature and relative moisture content. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. 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.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
