What Is Fatigue?

Fatigue is more than just feeling tired after a long day. It’s a prolonged and persistent sense of exhaustion that doesn’t improve with rest or sleep. While occasional fatigue is common, persistent fatigue may indicate an underlying issue.

Fatigue can manifest physically, mentally, or both. Symptoms may include lethargy, reduced focus, muscle weakness, and difficulty completing daily activities.
