Learning about yoga includes understanding the demands of a practice and how instruction can be tailored to the person taking part. Research on injuries and teaching offers useful context for that conversation. The studies below examine emergency-department records, published case reports, and feedback from a chair-based yoga trial. Each looks at a different question, so its findings need to be read within that setting.
A national estimate of injuries treated in emergency departments describes that group of injuries. A collection of case reports describes particular events. A teaching evaluation describes feedback about delivery. Keeping those distinctions in mind allows a reader to ask informed questions without turning a research figure into a prediction about their own practice.
A 2025 study in the Journal of the American Academy of Orthopaedic Surgeons examined US emergency-department data from 2004 through 2023. Researchers searched the National Electronic Injury Surveillance System for injury codes including yoga, then reviewed the narratives. The study reports 1,615 entries included in its analysis, corresponding to a national estimate of 63,280 yoga-related injuries over that period.
Strains and sprains were the most common injury type, accounting for 32.5% of the injuries. The lower trunk accounted for 24.2%, while shoulder and knee injuries each accounted for 9.0%. The study also reports that hip injuries represented a markedly larger proportion of total injuries among patients aged 45 and older.
The time period and setting matter. The national estimate covers injuries represented in emergency-department data across 20 years; it is not a count for a single year or a rate per yoga session. The percentage for an injury type describes its share within the study's injury data. It does not mean that the same percentage of everyone who practices yoga will experience that injury.
A 2026 Journal of Integrative Medicine systematic review identified 84 yoga-associated adverse events across 70 case reports and case series. The review describes these events as uncommon. Headstand was the most frequently implicated practice, appearing in 15 cases, or 18%, followed by forceful pranayama in eight cases, or 10%. The review reports pre-existing vulnerabilities in 54% of the people affected.
These are counts from published reports. The review does not provide a denominator of all people practicing yoga or all practice sessions, so it cannot establish an overall event rate. Nor do its counts provide a head-to-head comparison of the safety of different class styles. The useful distinction is between identifying practices in reported cases and measuring how often an event occurs across all practitioners.
The authors call for systematic pre-practice screening, tailored instruction, and targeted instructor training. That conclusion gives a clear focus for questions before class: how the teacher learns about individual circumstances, how instruction is adapted, and how particular practices are selected. It does not supply a universal sequence or a personal assessment.
The emergency-department study's finding about hip injuries among people aged 45 and older is a finding within its injury records. A separate 2025 BMJ Open evaluation of the Gentle Years Yoga trial considered teaching chair-based yoga to adults aged 65 and older with two or more long-term health conditions. These studies concern different populations and questions; the teaching evaluation is not an explanation for the emergency-department findings.
In the evaluation, 25 participants and 11 yoga teachers contributed feedback through interviews about a 12-week chair-based intervention. Their feedback generated a 21-item teaching exemplar. It covers class size, delivery formats, appropriate physical content, inclusion of personal beliefs through non-physical content, proactive teaching, communication, and visibility. The guidance addresses both face-to-face and online formats.
For someone considering chair-based practice, those topics suggest useful questions about delivery. How will demonstrations be made visible? How can a participant ask for an explanation? How is physical content chosen? What choices are available in the non-physical parts of a session? The evaluation presents teaching guidance for safe, accessible delivery, rather than a claim that a chair-based format guarantees a particular outcome.
A conversation before practice can begin with your experience of yoga, the parts of a class you want explained, and circumstances you want the teacher to understand. Ask how the teacher approaches pre-practice screening and tailored instruction, the priorities identified in the case-report review. Questions about headstands or forceful breathing can also be raised in light of the practices most frequently implicated in those reports.
If you have a health condition, check with a health professional. Research summaries provide context for discussion, while an individual conversation can address the questions particular to your situation. You do not need to turn survey percentages or case counts into a judgment about yourself to make that conversation useful.
Read each finding alongside its population, time period, and study design. Use the questions about screening, communication, and tailored instruction to guide a discussion before practice.
