A study in the November issue of the journal SLEEP is the first human experimental study to demonstrate that, despite comparable reductions in total sleep time, partial sleep loss from sleep continuity disruption is more detrimental to positive mood than partial sleep loss from delaying bedtime. According to the authors, the findings provide temporal evidence in support of slow wave sleep deficit as a putative biologic mechanism that could help explain the strong comorbidity between insomnia and depression.
