An irregular sleep schedule can increase a person's risk of depression over the long term as much as getting fewer hours of sleep overall, or staying up late most nights, a new study suggests.

Researchers assessed sleep with a wearable device, daily mood with a smartphone application and depression through the 9-item Patient Health Questionnaire (PHQ-9) over the demanding first year of physician training (internship).

The outcomes show;

--In 2115 interns, reduced total sleep time (TST), later bedtime, along with increased variability in TST and in wake time were associated with more depressive symptoms.

--Overall, the aggregated impact of sleep variability parameters and of mean sleep parameters on PHQ-9 were similar in magnitude.

--Within individuals, increased TST, later wake time, earlier bedtime, as well as lower day-to-day shifts in TST and in wake time were associated with improved next-day mood.

Conclusively, variability in sleep parameters substantially impacted mood and depression, similar in magnitude to the mean levels of sleep parameters. Interventions that target sleep consistency, along with sleep duration, hold promise to improve mental health.
