Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is achieved by amalgamating air temperature with the relative humidity readings. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
