What a Navy Warship Study Teaches Us About Mental Health in Deep Space

In August, Texas A&M Engineering reported on a study led by Dr. Ana Diaz Artiles, an associate professor of aerospace engineering, that took virtual reality to sea. Her team paired a VR headset with a compact scent device that releases smells timed to nature scenes, such as a walk on the beach or a stroll through a park. The goal is to support mental health in deep space by helping future astronauts manage the strain of long missions far from Earth. NASA funded the work.

To test the idea somewhere close to a spacecraft, the team went aboard a U.S. Navy warship during a two-week underway period. The results are published in Frontiers in Psychology. Twenty-nine active-duty personnel took part in three groups: one with no intervention, one with VR nature scenes, and one with VR nature scenes plus synchronized scents.

What did the Navy warship study find?

The group that used VR with scent showed a significant drop in negative affect immediately after a session. Participants who used VR rated the scenes as restorative. Over the full two weeks, stress, mood, and cognitive performance stayed largely stable in every group, and the authors saw no sustained benefit beyond that immediate lift.

The researchers describe the study as exploratory, with small groups, single 15-minute sessions, and no physiological measures. They call for more work on how long benefits last, how much exposure people need, and how individuals differ. That is a careful reading of the data, and it points to the right questions.

Why does a warship matter for mental health in deep space?

A warship underway is an isolated, confined, and extreme (ICE) environment, much like a spacecraft, which makes it a practical place to test support for long missions. Spacecraft, polar stations, submarines, and undersea habitats all fit the description. Crews live in tight quarters on fixed schedules, far from family and far from nature, and they still have to perform.

Our Chief Medical Officer, Dr. Marc Ó Gríofa, knows these settings firsthand as a NASA NEEMO aquanaut. After reading the Texas A&M work, he shared this reaction:

This is a very interesting operational validation, particularly the use of an underway Navy environment as an ICE analog. The distinction between immediate affective restoration and longer-term behavioral or physiological adaptation is particularly interesting to my team. Neurova Labs is approaching an adjacent problem through neuro-immersive regulation of physiological response and neurovascular function, with potential applications to long-duration spaceflight and other applications of neurophysiology linked to mental health. There may be considerable synergy between these approaches.

What helps crews adapt over a long mission?

What helps crews adapt over weeks and months is still an open question, and it is the core question for long missions. The Texas A&M team showed that a fifteen-minute visit to a virtual beach can lift mood in the moment. The next step is learning what supports adaptation over time, and how to see that change in the body as well as on a survey.

That is the problem Neurova Labs works on. Neurova Academy is a facilitator-led, neuro-immersive training program designed to support how people regulate their physiological response to stress. Its adaptive environments move through six phases (Activate, Challenge, Sequence, React, Switch, and Recover) and target 27 distinct brain regions, and the program's design is informed by fNIRS imaging. A full cycle is five daily sessions of about thirty minutes.

The program runs offline, collects no personally identifiable information in normal use, and needs about a square meter of space. Those traits matter on a ship, and they would matter on a spacecraft.

How does Neurova Labs measure what lasts?

Neurova Labs measures change at Day 30 with validated instruments and, where programs choose, with RNA gene expression in whole blood. In the 2026 cohort studies with the YMCA of Orange County, participants completed the PCL-5 and the Kessler-6 on Day 1 and again at Day 30. Trauma symptom scores improved 28 percent (29.1 to 21.0) and psychological distress improved 24 percent (14.0 to 10.6), each at p < 0.001. Sleep quality improved 22 percent.

For a physiological view, organizations can add the optional 22-marker CoreSignals Panel through iXpressGenes, a CLIA-certified, CAP-accredited laboratory. The panel measures RNA gene expression in whole blood. In a 2026 blood cohort of 103 members, the 26 who entered with the highest inflammatory burden saw their Global Inflammation Score, a composite from a 22-marker RNA panel, fall 48 percent by Day 30.

These are observational findings, and a controlled validation study is underway.

Where do the two approaches meet?

Put together, a crew could have quick restoration on a hard day and a training program that builds regulation over the course of a mission. The Texas A&M team showed that immersive technology can reach people inside an operational environment and help in the moment. Neurova Labs is focused on structured training and on tracking physiological change over time. We agree with Marc that there may be considerable synergy here, and we welcome the conversation with researchers working on spaceflight and other ICE settings.

The same need exists much closer to home. Dr. Diaz Artiles notes that the research could help Navy sailors on submarines, long-term hospital patients, and people with limited mobility. Add deployed service members and first responders on extended shifts, and the list of people living some version of isolation and confinement grows long. Our mission is to make brain training accessible to the people who carry the heaviest load, wherever they are.
