Note: The heat index, also known as 'feels like' or 'apparent temperature', quantifies the warmth felt when relative humidity is considered. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
