The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is the result of factoring in humidity to the air temperature, indicating perceived warmth. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
