Mental health problems can also contribute to insomnia. In particular, depression, anxiety or post-traumatic stress disorder can play a part disrupting sleep.
Does your sleeping routine and environment contribute?

What changes can I make before bed?
Making changes to your lifestyle, habits and where you sleep can help to improve your chances of falling asleep.
