What Works

Most treatments offered to veterans for sleep disorders aren’t the best treatments. The VA defaults to what’s available, what’s covered, and what’s familiar, not always what the evidence supports.


This pillar lists every treatment with a real evidence base for veteran sleep disorders, ranked by how strong that evidence is, with explicit notes on what each treatment doesn’t do and where it fails.

Seven evidence-graded treatments

Ranked by what the evidence says

Every entry below is a treatment with peer-reviewed evidence in veteran or military populations. The grade reflects the strength of that evidence, not the popularity of the treatment.

First-line by clinical guideline; multiple high-quality RCTs.

Useful for the right patient; evidence is mixed or context-dependent.

Biologically plausible; evidence base too thin to grade higher.

CBT-I (VA Settings)

Chronic insomnia

First-line; APA & VA/DoD CPG

Doesn’t address apnea, nightmares, or untreated PTSD as primary.

Treatment is necessary, not always sufficient

The treatments above work best when the diagnosis is correct, the underlying cause is named, and any active duty-driven disruption is being managed alongside.

Sleep Disorders

Make sure you know which disorder you actually have before choosing a treatment. Misdiagnosis is the most common cause of treatment

For Example

Nightmare Disorder in PTSD

Duty vs Biology

If duty is still actively producing the problem, treatment alone won’t be enough. The structural causes that need to be managed in parallel.

For Example

Watch Schedules and Circadian Biology

VA Assistance

If the treatment you need is denied or limited by the VA, this pillar covers your appeal options. Treatment records also strengthen disability claims

For Example

Sleep Disorders and Military Discharge

A note from the editors

Treatment is necessary but not always sufficient. The evidence-graded interventions on this page work best when the underlying cause has been correctly identified and when the duty environment that produced the disorder has stopped, or, when it can’t stop, when it’s being managed alongside the treatment. Treatment without diagnostic accuracy is guessing. Treatment without environmental management is bailing water with the tap still running.
