Digital Nature Experiences Reduce Anxiety, Stress, and Depression in Healthy Adults
Overview
This systematic review and meta-analysis of 24 studies demonstrates that exposure to virtual natural environments significantly reduces anxiety, stress, and depression in healthy adults. The effects are large for anxiety and moderate for stress and depression, supporting virtual nature as an effective mental health intervention.
Background
Stress, anxiety, and depression are major global public health challenges with increasing prevalence among adults. Nature exposure has been shown to alleviate these conditions, but urbanization limits access to natural environments. Virtual reality technology offers a scalable and accessible alternative by simulating immersive natural settings. Prior research on virtual nature exposure has been inconclusive for healthy adults, necessitating a focused quantitative evaluation.

Key Findings
Exposure to virtual natural environments significantly reduces anxiety levels in healthy adults with a large effect size (SMD = 0.82, p < 0.001).
Stress levels are moderately reduced following virtual nature exposure (SMD = 0.577, p = 0.003).
Depression symptoms also show moderate improvement after virtual nature exposure (SMD = 0.621, p < 0.001).
Virtual reality technology overcomes spatial and temporal barriers to nature access, providing immersive and controllable natural experiences.
The intervention methods vary widely, including 2D screens, 360° projections, and head-mounted displays with multisensory stimulation.
These findings support virtual nature exposure as a viable non-pharmacological intervention for mental health in non-clinical populations.
Clinical Implications
Clinicians can consider recommending virtual natural environment exposure as an accessible and effective strategy to reduce anxiety, stress, and depression in healthy adults, especially when direct nature contact is limited. The scalability and controllability of virtual reality interventions make them suitable for diverse settings and populations.
Conclusion
Virtual natural environment exposure produces significant reductions in anxiety, stress, and depression among healthy adults, highlighting its potential as a practical mental health intervention. This approach offers a promising alternative when real nature access is constrained.
