Note: The heat index, also known as 'feels like' or 'apparent temperature', offers an insight into how hot it feels when we factor in moisture content. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
