Lack of sleep associated with depression

A genetic study led by UCL specialists suggests that sleeping less than five hours per night may increase the likelihood of developing depressive symptoms. The study, which analyzed data from people with an average age of 65, found that short sleep was associated with the onset of depressive symptoms. The researchers used genetic and health data from over 7,000 participants and found that individuals with a stronger genetic predisposition to short sleep were more likely to develop depression.
