Causes can include stress and anxiety, too much caffeine or alcohol, or uncomfortable beds.

Some people seek professional help, with cognitive behaviour therapy for insomnia (CBT-I) being one course of action.

BBC Wales' Erin Sharrocks looks at some of the causes of insomnia, and considers when it might be time to see a doctor.
