This systematic review and meta-analysis examines the impact of immersive virtual nature (IVN) on nature connectedness in the general population. The study included six eligible papers (n=730) that compared IVN to non-immersive virtual nature, immersive virtual built environments, non-immersive virtual built environments, and actual nature. The risk of bias was predominantly low or some concerns. Meta-analyses showed a statistically significant overall effect for IVN compared to non-immersive virtual nature (g=0.26, 95% CI=0.06–0.45, I²=35%) and actual nature (g=-1.98, 95% CI=-3.21 to -0.75, I²=96%). Subgroup analyses revealed that computer-generated IVNs had a significant effect on nature connectedness (g=0.49, 95% CI=0.25–0.72, I²<0.5%), while 360° videos did not (g=0.03, 95% CI=-0.18 to 0.24, I²<0.5%). Shorter IVN exposures (<5 min) were more effective in eliciting nature connectedness (g=0.46, 95% CI=0.27–0.67, I²<0.05%), while longer exposures (>5 min) showed a marginally significant effect in favor of the comparison condition (g=-1.41, 95% CI=-2.80 to -0.01, I²=89%). The study concluded that IVN may be an effective tool for promoting nature connectedness, but the evidence is limited and mixed. Recommendations for future research are discussed.This systematic review and meta-analysis examines the impact of immersive virtual nature (IVN) on nature connectedness in the general population.
