Hot yoga warrants clinician review for people with heart conditions, cardiologists say

Current assessment: The available evidence supports a cautious version of the reported warning: people with a heart condition should not assume hot yoga is safe without individualized medical advice, and some people,particularly those with unstable symptoms, impaired blood-pressure control, certain rhythm disorders, heart failure, or medications that affect heat tolerance,will be advised to avoid it. The record does not support a universal claim that every person with every heart condition must avoid all heated yoga.

Reported facts: Yahoo Health published or republished an August 23 item under the headline “Cardiologists Warn: People with Heart Conditions Should Avoid Hot Yoga.” The underlying report, published by Parade on August 22, quoted cardiologist Dr. Travis Benzing and interventional cardiologist Dr. Said Ashraf. They described heat, exertion, sweating and fluid loss as factors that can increase cardiovascular workload or alter blood pressure, and said people with heart conditions should discuss hot yoga with their cardiologist before participating.

Supporting evidence: The reported concern is consistent with established institutional guidance, although that guidance is generally framed as individualized precaution rather than a categorical ban. Mayo Clinic Orthopedics & Sports Medicine describes hot yoga as vigorous exercise in a warm, humid studio and says it is probably best skipped by people with heart disease, dehydration problems, heat intolerance, or a prior heat-related illness. ([sportsmedicine.mayoclinic.org](https://sportsmedicine.mayoclinic.org/news/what-is-hot-yoga/?utm_source=openai)) The National Center for Complementary and Integrative Health similarly identifies overheating and dehydration as special hot-yoga risks and advises older adults and people with health conditions to discuss individual needs with their health-care providers and instructors.

Physiological evidence gives the warning a plausible basis. In a small uncontrolled study of 16 apparently healthy, experienced female Bikram-yoga practitioners, heart rate and estimated myocardial oxygen consumption rose substantially during a 90-minute class, while diastolic blood pressure fell during much of the session. Those findings do not measure risk in cardiac patients, but they are consistent with the concern that heat, postural changes and exertion can create a more demanding setting than non-heated yoga. ([pubmed.ncbi.nlm.nih.gov](https://pubmed.ncbi.nlm.nih.gov/30698456/?utm_source=openai)) The American Heart Association also advises people with cardiovascular disease to consult a health professional before beginning exercise or moving activity into hot conditions, noting that several common cardiovascular medicines can intensify the body’s response to heat.

Limitations and competing evidence: The Parade/Yahoo report is clinician commentary, not a new clinical guideline or a study of hot-yoga injuries among people with diagnosed heart disease. Its quoted advice applies to a broad group of conditions that differ materially in risk. The small Bikram-yoga physiology study involved healthy regular participants, not people with coronary disease, heart failure, arrhythmias or valve disease; it therefore cannot quantify adverse-event risk for those groups. Conversely, evidence that some forms of yoga can be beneficial in cardiac rehabilitation does not establish that heated, vigorous yoga is appropriate for cardiac patients. The relevant distinction is the added thermal and dehydration stress, not yoga as a single uniform practice.

There are also condition-specific reasons for caution. European Society of Cardiology sports guidance advises people with Brugada syndrome to avoid increases in core temperature above 39°C and gives warm, humid exercise conditions as an example. That is not a guideline directed specifically at hot yoga or at all heart conditions, but it illustrates why diagnosis-specific advice matters.

Current conclusion: A cautious reading is that the Yahoo/Parade story identifies a legitimate safety issue but overstates it if interpreted as a blanket prohibition. The available record supports advising people with diagnosed heart conditions to obtain clearance from the clinician managing their condition before attending hot yoga, rather than treating heated classes as equivalent to gentler, room-temperature yoga. It does not establish a single rule for all cardiac diagnoses or prove that hot yoga causes cardiac events in all such participants. Information that would materially sharpen this assessment includes diagnosis-specific guidance from cardiology societies, medication considerations, class heat and humidity levels, and studies measuring adverse events in cardiac populations.
