Chronic Fatigue Syndrome (CFS) is distinguished by profound and debilitating fatigue that is typically exacerbated by both physical and mental activities. This characteristic is often referred to as "post-exertional malaise," where individuals experience a significant worsening of fatigue and other symptoms after engaging in activities that were previously manageable.

In contrast, options that suggest fatigue improving with activity or being easily relieved by rest do not align with the core experience of CFS. Patients often find that their level of fatigue does not improve with rest, and instead, they may feel more exhausted after engaging in activities, regardless of their intensity. Additionally, fatigue lasting less than six months does not meet the diagnostic criteria for CFS, which requires persistent fatigue lasting six months or longer. Thus, identifying the characteristic that aligns with worsening symptoms following exertion is crucial for understanding CFS.
