“If only I could get a good night’s sleep my mood would be much better.”
Many people who suffer from chronic depression are aware of the relationship between the quality of their sleep and their levels of mood and anxiety.
A study published in the April 2016 addition of the British journal, Lancet Psychiatry, supports this view.
1100 internet users (aged 18–64 years) with insomnia and depression symptoms who did not meet criteria for major depression were randomly assigned to receive SHUTi, a 6 week, online cognitive behavioral therapy for insomnia program, or HealthWatch, an interactive internet-based placebo control program.
As you can see in the graph on the right, the SHUTi program was associated with a 
significant and rapid reduction in symptoms of depression as measured using a standard rating scale, the PHQ-9.
Scores on the PHQ-9 were reduced by 50% by week 5 of the program. And these scores remained at that same level for the full 25 weeks of follow up. Confirming our experience with the SHUTi program: it is effective at improving sleep long after the user completes the program.
The SHUTi program was associated with reductions in symptoms of depression, anxiety, and suicidal ideation.
