Chronic Fatigue Syndrome (CFS) is characterized by a profound and persistent fatigue that is not alleviated by rest or sleep, which is a key distinguishing factor from general fatigue. In CFS, the fatigue is often debilitating, lasting for six months or longer, and does not improve with normal periods of rest. Individuals with CFS may experience extreme tiredness that significantly interferes with their daily activities and is often accompanied by additional symptoms such as cognitive dysfunction, sleep disturbances, and other systemic issues.

While muscle pain, daytime drowsiness, and changes in energy levels after eating can be symptoms associated with CFS, they are not definitive criteria for distinguishing it from general fatigue. Muscle pain can occur in various conditions, daytime drowsiness might relate to other sleep disorders, and variations in energy following meals can also be present in a range of other health issues. The hallmark trait of CFS is the persistent fatigue that is unrelieved by sleep, which is crucial for proper diagnosis and understanding of this condition.
