Mental fatigue is a state in which our alertness of mind and the ability to perform daily tasks reduces. Mostly mental fatigue happens to people who are continuously involved in some sort of cognitive activity.
A cognitive activity is one which involves mental stamina for processing, acquiring and organising information and then retrieving it from memory for use in other similar situations. Reasoning, thinking and decision-making are all examples of cognitive activity.
That said, mental fatigue can happen to anyone. Many of us feel mentally and emotionally drained a lot of the time. And working continuously in stressful conditions can cause mental fatigue even in the best among us.
The symptoms of mental fatigue are lethargy, pessimistic thoughts, inability to concentrate, inability to sleep and anxiety. Mental exhaustion can occur due to various social, emotional and financial reasons.
Mental fatigue can be managed by talking about your problems with your loved ones or a specialist, by trying to manage and reduce stress, by taking out time for your self, by indulging in various creative activities or through meditation.
