Retreat Safety and Intensive Practice: Risks, Screening and Questions to Ask

If you need help right now

In the US, call or text 988 if you are in distress, and call 911 in an emergency. [1] At a retreat, tell a staff member or teacher at once if you feel unsafe, and leave if you need to. You can always choose to leave a retreat. If you are in another country, use your local emergency number.

What "intensive" means here

Intensive practice means many hours of meditation a day, often in silence, over days or weeks. This page covers risks as the studies describe them. It does not list or recommend any retreat. For what a typical retreat involves, see meditation retreats: what to expect.

What the evidence shows

No study I found measures how often serious problems happen on retreats. Here is what exists.

1. Are unpleasant experiences common among regular meditators?

   Unclear

   In an online survey of 1,232 regular meditators, 25.6 percent reported particularly unpleasant experiences they thought were caused by practice. Having attended a retreat, and doing only insight-type practice, were linked with reporting them. [2]

   Self-selected survey. Cannot show retreats cause it.

2. What kinds of difficulty are described?

   Unclear

   Interviews with Western Buddhist practitioners and teachers produced 59 experiences across seven areas. Distress ranged from minimal and passing to severe and lasting. [3]

   Qualitative and survey. Good for variety, not for rates.

3. Can intensive practice trigger psychosis?

   Unclear

   A 31-year-old woman became psychotic on day 3 of a 7-day retreat and recovered after treatment. [4] A series of five cases described psychosis after meditation. [5]

   Case reports only. Rare, but real.

4. What conditions were linked?

   Unclear

   Reviewers listed pre-existing vulnerability, fasting, sleep deprivation, isolation and lack of screening. [4] The series authors added unsupervised practice, sudden increases in practice and mismatched expectations. [5]

   Expert opinion from cases.

Caution about the 2025 report: it is a conference abstract reviewed by a professional faculty, not by standard journal peer review. [4]

What does not apply to retreats

The finding that an 8-week MBSR course was not linked to more harm than a waitlist does not tell us about a ten-day silent retreat. [6] Those are different settings. Lindahl and colleagues also point out that Buddhist texts themselves describe a range of effects beyond health benefits. [3]

Who should check first

Talk with a clinician before an intensive retreat if you have had psychosis, mania or severe trauma, are in a depressive or anxious episode, or are unsure. Read who should check with a clinician. Case-series authors recommend collecting mental health history before enrolling people. [5]

Questions to ask before you book

These come from the risk factors above and from how a teacher code describes retreat conditions. They are a practical checklist, not a tested standard.

• Do you ask about my mental health history, and what do you do with the answer?
• Are food, water or sleep limited? The series authors advise against coupling meditation with sensory deprivation or marked restriction of sleep, water or food. [5]
• Can I take breaks, get fresh air, or switch to gentler practice, such as guided or open-monitoring meditation? [5]
• Who can I talk to if I struggle, and is any health professional available? Retreats "should offer tailored practices and provide professional mental health support," says the 2025 abstract. [4]
• Can I leave at any time, and how do I get home?
• Do you have a written ethics code, and who do I contact with a concern? One UK teacher code notes that the conditions of intensive silent retreat can amplify the power gap between teacher and student. [7] See teacher misconduct and red flags.
• What is the teacher's training? NCCIH advises asking about the instructor's training and experience. [8]

There is no government regulator for meditation teaching that I found in the sources read, so these checks fall on you. See how to find a teacher or class.

Warning signs during a retreat

Seeing or hearing things others do not, or a firm belief that you or your family are in grave danger, are urgent signs. The 2025 case began this way. [4] So are thoughts of ending your life. Call 911 or 988 in the US, and ask staff for help. For milder trouble, read when to stop or pause meditating.
