About one in five people in the UK have some difficulty with sleeping.
Sleep problems can be a key sign of common mental health conditions and sleep disorders can actually trigger mood and other emotional disorders.
Sleep difficulties are particularly common in women, children, and those over 65, although everyone can be affected.
Everyone needs different amounts of sleep. You should usually feel refreshed and not sleepy during the daytime.
Poor sleep can be caused by worrying about being awake or not sleeping enough; temporary problems (e.g. a strange bed); stress, anxiety or depression; sleep apnoea (where the airways close while sleeping); other illnesses such as coughing or pain; needing the toilet; stimulants such as coffee, alcohol or smoking; illegal drugs or prescription medication.
