Fatigue is a common condition characterized by a persistent sense of tiredness, weakness, and a lack of energy. It is not merely feeling drowsy or sleepy but encompasses a more complex state of reduced physical and mental capacity.

Recognizing and addressing fatigue is crucial for maintaining overall health, ensuring safety (especially if operating machinery or driving), and enhancing quality of life.
