Mental fog, often referred to as "brain fog," is a term used to describe a temporary state of mental cloudiness or confusion. People experiencing mental fog may find it difficult to concentrate, remember information, or make decisions. This condition can be caused by various factors, including lack of sleep, stress, poor diet, or certain medical conditions. While mental fog is not a medical diagnosis, it can significantly impact daily life and productivity. Addressing underlying issues, such as improving sleep quality or managing stress, can help alleviate symptoms. Maintaining a balanced diet and staying hydrated are also important for cognitive function and clarity.
