Lethargy is fatigue due to unknown reasons. A person can be tired, weary, listless, lack concentration and focus or have reduced energy. The cause of lethargy needs to be determined and serious illness needs to be ruled out. Certain medications may also cause lethargy and fatigue.
Caution should be taken in anyone who presents with lethargy or unexplained fatigue. If the person is on medication, massage can increase or decrease its efficacy. If a person is otherwise deemed healthy massage can help to restore energy.
