What is disturbed sleep (insomnia and hypersomnia)?
Disturbed sleep is a change in your usual sleep pattern. It can range from insomnia (inability to either fall or stay asleep) to hypersomnia (inability to stay awake). It is estimated that nearly half the people with cancer have sleep disturbance. Sleep problems may include any or all of the following: • Difficulty falling asleep (more than 30 minutes to fall sleep). • Difficulty staying asleep (having nighttime awakenings lasting 30 minutes or more). • Waking up too early. • Non-refreshing or poor quality sleep. Hypersomnia is different from fatigue. You may have hypersomnia if you are sleeping more than 10 hours per night and still sleep during the day.
