Fatigue

Of course, one of the most obvious side symptoms of insomnia is fatigue, but many people with anxiety problems, whether or not they have insomnia, feel abnormally tired, foggy, and fatigued throughout the day.

The physical symptoms of anxiety are caused by excessive activity in your sympathetic nervous system, which results in a constant state of hyper-alertness. When this system is activated for an extended amount of time, it might cause persistent weariness. Everyone gets fatigued from time to time. Excessive or chronic tiredness, on the other hand, is a frequent symptom of anxiety that can have a negative influence on your life and make it difficult to carry out daily tasks.
