Sleep Disorders

Sleep is a daily period of physical and mental rest when the body regenerates itself. It is necessary for the biological function of the person and good sleep helps conduct the daily activities and exercise.


Sleep disorders are one of the most common symptoms seen in Chronic Fatigue

Syndrome and chronic fatigue due to other causes such as cancer, rheumatoid

arthritis, Parkinson's disease and others. Sleep disorders, in general, can take three


  1. difficulties before bedtime,

  2. difficulties during the night and

  3. difficulties in the morning awakening.



The person with chronic fatigue can have one of these disorders or all together.

Often, one can sleep longer hours than normal and yet there is no rest meaning that the quality

of sleep is disturbed.


During the course of Graded Exercise Therapy a discussion of the sleep disorders takes place and techniques to improve and maintain a proper sleep, as recommended by the National Institute for Health and Care Excellence UK [1], are applied. These techniques include:


  • Explanation of the role and impact of disturbed sleep in CFS and chronic fatigue,

  • identification of changes in sleep patterns and their impact on symptoms,

  • advice on good sleep hygiene,

  • implementation of gradual changes in sleep patterns and

  • regular review of sleep cycle and sleep habits.
