Sleeping with light on ‘can cause depression’ – Metro London 18/11/2010
Metro writes today that ‘Sleeping with light on ‘can cause depression’. Research shows that people who like to sleep with the light on could develop depression. Scientists say that even a small amount of light causes changes in the brain that are linked to depressive disorders. Tracy Bedrosian from Ohio State University says that even dim lights is sufficient to cause depressive like behaviours in hamsters, which could explain the changes scientists noticed in their brains/hippocampus after 8 weeks of exposure.
‘The hippocampus plays a key role in depressive disorders, so finding changes there is significant.’
