Lethargy

For the band, see Lethargy (band).

Lethargy is defined as a state of tiredness, weariness, fatigue, or lack of energy. It can be accompanied by depression, decreased motivation, or apathy. Lethargy can be a normal response to inadequate sleep, overexertion, overworking, stress, lack of exercise, or boredom. When part of a normal response, lethargy often resolves with rest, adequate sleep, decreased stress, and good nutrition.[1][2]
