Links between sleep patterns and symptoms of depression, PTSD, and sleep problems in US military veterans

Circadian Biology Weekly Brief ↗PubMed ↗DOI ↗

Updated Oct 7, 2026

Abstract

Chronotype is associated with depression and PTSD in military veterans.

Chronotype refers to an individual's natural preference for being active during certain times of the day.
Military veterans experience higher rates of depression and PTSD compared to the general population.
This population also reports more severe sleep difficulties than non-veteran community-residing adults.
Limited research exists on the relationship between chronotype and mental health outcomes in veterans.
