Very short sleep duration (less than 6 hours per night) is strongly associated with increased risk for PTSD, depression, panic syndrome, obesity, and suicide attempts in redeployed soldiers.
If you are a soldier or veteran returning from deployment, prioritize getting more than 6 hours of sleep. Short sleep is linked to higher risks of mental health issues and physical health problems. Seek help if you are struggling with sleep, as it may be a sign of underlying health risks.

Soldiers with VSSD were at increased risk for all conditions relative to those with either short or normal sleep duration... The strongest predictor of PTSD was sleep duration < 6 h/night (AOR 4.7; 95% CI 3.2-6.9). Depression was strongly associated with sleep duration (AOR 7.9; 95% CI 2.5-25.4)... VSSD (AOR 3.3; 95% CI 1.3-8.9)... predicted obesity... Both VSSD (AOR 3.8; 95% CI 1.5-9.2) and symptoms of insufficient sleep (AOR 2.4; 95% CI 1.4-4.1) predicted suicidal ideation or having attempted suicide.
Why this rating
Cross-sectional study with large sample size but self-reported data and inability to determine causality.
