Though the loud groans associated with catathrenia can be disturbing to a bed partner, the condition usually isn’t considered to be dangerous. In some cases, it can interfere with a good night’s sleep, but it’s generally not a symptom of any harmful health condition.
One other risk associated with catathrenia is that it may mask OSA or other sleep disorders. If your bed partner notices snoring, paused breathing at night, or other potential sleep disorders, such as parasomnia (sleep walking or sleep talking), be sure to talk with a doctor or other healthcare professional soon.
