Recovery period is prolonged, usually taking 24 hours or longer or prolonged recovery after exertion refers to the recovery time after over-exertion causes post-exertional malaise (PEM) or post-exertional symptom exacerbation. Symptoms caused by PEM do not stop when the over-exertion ends, even when the exertion may be minimal.[1]

The prolonged recovery time in ME/CFS patients is one of the compulsory criterion of post-exertional neuroimmune exhaustion (PENE), which is defined by the International Consensus Criteria for ME, and is required in many other diagnostic criteria definitions of ME/CFS including the current CDC criteria.[2][1]
