Immersive 360° group mindfulness pilot lowers immediate autonomic arousal in health‑sciences students

A brief, uncontrolled pilot tested MK360 - a projection-based, group mindfulness model - with medical and nursing students at the University of Lleida and found immediate reductions in autonomic arousal alongside signals of lower perceived stress. The study is notable because it used a shared multisensory room without head-mounted displays or wearables, making the format more practical for campus wellness programs.

Authors Roma and Yuguero ran a single-site pre–post pilot over four weeks. Students attended four approximately 20-minute MK360 sessions, and heart rate plus systolic and diastolic blood pressure were recorded immediately before and after each session. The Perceived Stress Scale (PSS-14), the [...] was used to assess perceived stress across the pilot. The title supplied for the report emphasizes reduced immediate autonomic arousal; the supplied excerpts do not include numeric pre/post physiological values or p-values.

MK360 is described as “short, guided mindfulness with immersive 360° projection in a shared multisensory room environment without wearables.” The system also provides multimodal sensory input: “Our research applied innovative technology through the MK360 immersive experiences system, which provides auditory and visual stimuli to enable participants to navigate within a virtual world.” That projection-based approach preserves group presence and avoids the logistical hurdles of individual headsets, which may make it easier to scale brief interventions in student services or hospital education centers.

On subjective outcomes, the pilot recorded that “Among completers, 50.0% reported feeling somewhat better emotionally.” Overall feasibility and tolerability were positive: “MK360 was feasible and well tolerated, with signals consistent with reduced perceived stress over 4 weeks.” Those signals point toward potential practical value for trainers and campus mindfulness coordinators who need short, repeatable practices that fit into clinical training schedules.

At the same time, the authors are explicit about limits. “Given the uncontrolled design and small sample, causal inference is not warranted; controlled studies should confirm effectiveness, examine dose–response, and compare delivery formats.” The supplied materials also show a discrepancy with other descriptions of MK360 that reference six VR sessions and a non-clinical adult sample - a protocol that does not match the four-session student pilot - and further clarification from the authors would be useful.

For mindfulness program leaders, the pilot suggests projection-based group practice can deliver immediate physiological relaxation and acceptable user experience without headsets. The next steps are straightforward: replicate MK360 in randomized designs, report session-by-session autonomic data and PSS-14 scores, and map which guided practices - for example body scan or breath work - drive the strongest reductions in stress and arousal. If controlled trials confirm the signal seen here, multisensory projection rooms could become a practical, low-barrier option for campus and clinical mindfulness offerings.
