Mindfulness-based interventions produce small-to-medium improvements in self-reported interoceptive awareness, according to a meta-analysis of 29 randomized controlled trials involving 2,191 participants (77.8% female, mean age 32.8 years). The overall effect size was g = 0.31, with mindfulness-based programs showing the largest effects (g = 0.41). Improvements in interoception were similar in size to improvements in self-reported mindfulness and were linked to reductions in psychological distress. No evidence of publication bias was found, and no other moderators—such as practice dosage or clinical sample—were significant. The findings suggest that mindfulness training leads to adaptive changes in how people subjectively experience bodily signals, which may contribute to better mental wellbeing.
A longitudinal study with nearly 10,000 US and UK adults found that people who used psychedelics during a two-month period reported greater increases in unusual visual experiences compared to those who did not. The effect was strongest among first-time users. These visual experiences occurred after the acute drug effects had worn off. The findings support earlier case reports and cross-sectional studies suggesting that naturalistic psychedelic use may be linked to persistent visual phenomena, though further longitudinal research is needed to clarify cause-and-effect relationships.
