Note: The heat index, also known as 'felt air temperature' or 'feels like', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
