There's a definite link between sleep deprivation and depression.
A new study now suggests that those who tend to be active at night are more likely to suffer from depression.
Researchers in Finland recruited over 6,000 individuals aged between 25 and 74. They found that those who tended to carry out their daily activities in the evening were 2.7 to 4.1 times more likely to show indicators of depression.
These indicators included a diagnosis of a major depressive episode, diagnosed depression, treated depression and the use of antidepressants.
The result is likely to be a better chance of getting a good night's sleep and perhaps even a reduced risk for depression.
