Fatigue describes an overall feeling of tiredness or lack of energy. It isn’t the same as feeling generally sleepy or drowsy. When you’re fatigued, you have no motivation or energy to do the simplest of tasks. Being sleepy may be a symptom of fatigue, but it is not the same thing. Tiredness is easily relieved by sleep and rest, whereas, fatigue symptoms are often an overwhelming feeling of tiredness that isn’t relieved by sleep or rest.
Fatigue is a lingering tiredness that is constant and limiting. You may wake in the morning and feel as though you haven’t slept and you may feel too exhausted to manage your daily affairs. Fatigue can come as a result of mental health issues, physical health factors, and some lifestyle factors.
