“…For example, perfectionist or conscientious individuals may strenuously attempt to keep up with their usual standards despite the extra challenges, and end up more stressed and fatigued as a result (e.g., [9]). It is suggested that acute fatigue can become chronic via a number of mechanisms including level of physical activity (e.g., too high or too low; [42]), fearful beliefs about fatigue or the effects of fatigue (e.g., [38]) or emotional difficulties such as anxiety or depression [30,32]. Cognitive behavioural interventions typically aim to improve symptoms and functioning by (a) encouraging patients to achieve a balance between activity and rest, (b) gradually increasing activities, (c) establishing a sleep routine, (d) addressing unhelpful beliefs (e.g., about fatigue or high standards) and (e) paying attention to relapse prevention.…”
