In 2026, the Journal of Clinical Sleep Medicine published a new nationally representative study regarding U.S. veterans and sleep disorders. The research was authored by Robert H. Pietrzak alongside Ian C. Fischer and Emily McCarthy. John C. DeViva and Peter J. Na also contributed to the published findings. Their work analyzed data from 2,632 veterans through the National Health and Resilience in Veterans Study.
The researchers compared these recent results with a similar veteran sample collected between 2019 and 2020. This earlier baseline provides crucial context for understanding recent trends. The study places the observed increase in sleep disruptions within the context of the acute and sustained changes associated with the COVID-19 pandemic. While prior research documented worsening sleep symptoms during the pandemic, the new study does not claim that the pandemic alone caused the higher prevalence.
Instead, it establishes an updated baseline for understanding how sleep disruptions affect the broader veteran population today. The survey was carefully designed to reflect the demographic composition of approximately 20 million adults who have served in the armed forces. The primary focus of the study was the increasing prevalence of both clinical and subthreshold insomnia. The findings show a clear upward trend in severe sleep problems since the previous data collection period.
The study authors characterize the combined prevalence of these insomnia categories as a substantial public health concern among veterans. Many service members are trained to view sleep deprivation as an unavoidable part of the job. This mindset often carries over into civilian life. Veterans may subsequently treat chronic sleep problems as a minor inconvenience rather than a medical issue.
I remember waking up after a poor night of sleep and realizing that my training recovery was taking much longer than it used to. I realized that readiness is more than just pushing through the fatigue. It requires a dedicated approach to sleep and hormonal health, which completely shifted how I view long term capability. Proper sleep is a fundamental requirement for maintaining a resilient and healthy body composition over time.
When sleep problems are ignored, they can compound existing physical and mental health challenges. The researchers present insomnia as a potentially active risk factor that spans multiple diagnoses. It is not just a secondary symptom of another condition. This means poor sleep can actively worsen other psychiatric struggles.
The study noted that veterans with insomnia classifications shared several demographic risk factors. They were younger on average and more likely to belong to racial or ethnic minority groups. These veterans were also more likely to report greater lifetime trauma exposure and military sexual trauma. Furthermore, they experienced higher rates of homelessness and chronic medical conditions.
This reality emphasizes the need to view sleep quality as a central component of veteran well-being. Good rest supports long-term physical performance and healthy aging.
The study measured sleep issues using the seven-item Insomnia Severity Index. This tool assesses difficulty falling asleep and trouble staying asleep. It also measures early waking, daytime impairment, sleep-related distress and general dissatisfaction with sleep. Veterans scoring 15 or higher were classified as having clinical insomnia.
Those scoring between 8 and 14 met the criteria for subthreshold insomnia. It is important to note that a screening category is not the same as a formal diagnosis. Individual veterans should receive clinical evaluation rather than infer a diagnosis from a survey score alone.
The researchers found that clinical insomnia increased from 11.4 percent in the 2019 to 2020 sample to 13.6 percent in the newer study. This represents a relative increase of nearly 20 percent. Subthreshold insomnia also increased from 26.0 percent to 29.7 percent across the compared samples. Taken together, more than 43 percent of veterans in the newer sample met the criteria for clinical or subthreshold insomnia.
The statistical associations between these sleep categories and mental health struggles are significant. The study observed a pattern consistent with a severity gradient. Subthreshold insomnia was linked to elevated psychiatric risk, while clinical insomnia was linked to still larger associations. After adjusting for age, trauma exposure, medical burden and other characteristics, subthreshold insomnia showed clear risks.
It was associated with two to six times higher odds of depression, anxiety, PTSD and suicidal ideation. Clinical insomnia was associated with two to twelve times higher odds of those psychiatric outcomes. The study coverage specifically reports nearly four times higher odds of future suicidal intent for those with clinical insomnia.
It is important to note that these reported associations are observational. The study design does not prove that insomnia directly causes depression, PTSD, anxiety or suicidal behavior. The newer study and the older comparison sample may not have identical recruitment procedures or response rates. However, the data strongly suggests that worsening sleep is a clear indicator of elevated psychiatric risk.
These updated statistics support a shift in how veterans and clinicians manage sleep health. The study authors argue that the large size of the subthreshold group justifies earlier identification and intervention. Veterans do not need to wait until their sleep disturbance reaches a clinical threshold before seeking help. Identifying sleep issues early can prevent the escalation of related mental health burdens.
The term subthreshold does not mean harmless. In this study, the lower scoring group was still associated with substantially higher odds of several mental health outcomes. Veterans should treat persistent difficulty falling asleep or functioning during the day as a serious health concern. This requires discussing symptoms with a primary care provider, a mental health professional or a sleep clinician.
A thorough evaluation can help identify related conditions like PTSD and depression. Clinicians can also review anxiety symptoms, medication effects and potential substance use. Veterans concerned about their sleep may also need to discuss a referral for a sleep study to check for other sleep disorders.
The Department of Veterans Affairs lists evidence-based treatment resources for insomnia and several commonly co-occurring mental health conditions. One structured treatment approach is cognitive behavioral therapy for insomnia. VA Houston describes this therapy as a structured treatment that changes sleep-related behaviors and thoughts. It does not rely primarily on medication, and some VA settings offer this program virtually or in person.
This behavioral approach is crucial because self-medication strategies are often ineffective and potentially harmful. Relying on alcohol or non-prescription sedatives should never substitute for a proper clinical evaluation. The study itself does not test self-medication strategies, so this guidance serves as clinical prudence rather than a direct finding. Family members, peers and clinicians must take the combination of worsening sleep and worsening mood very seriously.
Insomnia may be intertwined with trauma exposure, homelessness, chronic medical illness or substance use. Treating sleep in isolation may therefore be insufficient for some veterans. However, treating insomnia should still be viewed as a core component of efforts to reduce psychiatric morbidity and suicide risk.
As we recognize the profound links between sleep disturbances and severe psychiatric outcomes, will future veteran healthcare systems universally mandate early sleep interventions as the first line of defense in mental health treatment?
