Heat index's context suggests values are appropriate for shady areas and slight breezes. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', quantifies the warmth felt when relative humidity is considered. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 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.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation. 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. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
