Brain fog意思

"Brain fog" is a term used to describe a feeling of mental confusion, haziness, or lack of mental clarity. It's often used to describe the experience of having difficulty focusing, thinking clearly, or remembering things. People may describe brain fog as feeling like their mind is "foggy" or "cloudy," and it can make it difficult to perform everyday tasks or concentrate on complex mental activities.

Brain fog can be a symptom of various medical conditions, such as chronic fatigue syndrome, fibromyalgia, depression, or certain types of infections. It can also be a side effect of medications, lack of sleep, stress, or a poor diet. In some cases, the cause of brain fog may not be identifiable.
