It’s often been suggested that insomnia is a purely psychological problem. Recently, however, scientists have been able to demonstrate that this is not the case. Analysing data from over 100,000 people, they were able to identify seven genes associated with an increased risk of the condition. They also noted a genetic relationship with traits like depression and anxiety disorders. According to neuroscientist Anke Hammerschlag, "these characteristics tend to go hand in hand with insomnia. We now know that this is partly due to the shared genetic basis".
