Note: The heat index, also known as 'apparent temperature' or 'feels like', takes into account both air temperature and humidity to illustrate what people actually feel. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
