It is common to sometimes struggle with our sleep; from time to time, we might find it difficult getting off to sleep or we might wake up in the night. These difficulties often settle down after a short while, but if they continue over a longer stretch of time it can start to affect our lives. 

If you regularly have problems sleeping well, this is known as having a sleep disturbance. Some sleep disturbances may be caused by circumstances in your life, such as a stressful event, or there may be an underlying health condition.
