Meditation is widely praised as a popular way to relieve stress and improve mental health, but a study by psychologist Nicholas Van Dam’s team reveals a "meditation paradox": nearly 60% of practitioners have experienced adverse effects, some even affecting daily life. This episode interprets the key findings of the study, clarifies the specific manifestations of meditation’s adverse experiences, high-risk groups, and how to rationally view this wellness practice.

Key Findings

1. Adverse experiences are far more common than previously thought
   Previous studies claimed the incidence of meditation side effects was only 1%, but this was due to vague open-ended questions—many people concealed experiences due to stigma or failure to recognize the connection. Van Dam’s team used a detailed 30-item checklist to survey nearly 900 U.S. adults, finding that nearly 60% of practitioners reported at least one adverse experience, 30% of whom found it distressing, and 9% experienced functional impairment (affecting work, relationships, or daily tasks).
2. Adverse experiences are not "minor discomfort"—they may involve serious reactions
   These adverse effects include panic attacks during or after meditation, sudden distressing memories (similar to PTSD symptoms), depersonalization (feeling unreal or detached from oneself/world), emotional numbness, and unusual sensory experiences. They are not just simple "drowsiness" or "discomfort"; some are clinically significant.
3. Two high-risk groups: people with pre-existing distress + intensive practitioners
   The study identified two key risk factors: first, individuals with significant mental health distress (such as anxiety or depression) in the 30 days before starting meditation—they sought meditation to relieve pain but are more prone to adverse effects; second, those engaging in intense practice, such as residential retreats involving hours of daily meditation for days or weeks, who have a significantly higher risk of functional impairment, similar to a "dose-response effect."
4. Core insight: Meditation requires "informed consent"
   The study does not negate meditation’s value—it truly benefits many. The key is to break the myth that "meditation is completely harmless" and disclose potential risks in advance, just like with drugs or therapies. Practitioners should choose based on personal circumstances: those with mental distress should proceed cautiously or under professional guidance; avoid blindly pursuing intense practice—gradual progression is safer.
5. Unanswered question: Causation needs verification
   Current research only proves a correlation between adverse experiences and meditation, not whether meditation worsens distress or if people with pre-existing issues are more sensitive to experiences. Longitudinal studies are needed to clarify the causal relationship.

Summary

Meditation is not a "universally applicable, zero-risk" cure—its adverse experience rate is far higher than previously thought. Understanding risk factors and rationally choosing practice methods is responsible for one’s own health. Curious about how to identify warning signs in meditation and practice scientifically?
