Hot Stone Massage

Earlier uses of heated stones

A trade-magazine history by Pat Mayrhofer, founder of a company that supplies massage stones and heaters, states that heated stones were used in China more than 2,000 years ago and that stones were applied to the body in North and South America, Africa, Europe, Egypt and India. The article names no specific sources for these statements, and its author has a commercial interest, so it is best read as an industry account and not as established history.

A 2009 article on the forms of ancient Chinese stone needles, published in a Chinese medical-history journal, concludes that the use of stone needles for hot stroking, massage and knocking at the body surface, which some scholars had proposed, does not belong to the category of ancient stone needles. This is a point about how one implement is classified. It does not show whether heated-stone practices existed or did not exist, and only the English abstract was read for this page.

The modern spa and clinic method

The trade history and a university health-sciences patient page both credit Mary Nelson, an Arizona massage therapist, with introducing LaStone Therapy, and the trade history gives the year as 1993. That date rests on the trade article alone. Nelson also wrote a 2010 article on avoiding burns for the American Massage Therapy Association (AMTA) journal, which is practitioner guidance and not a historical account, so the main published descriptions of the modern method come from its originator and from suppliers.

The trade history describes a shift from kitchen appliances to heaters designed for massage, again from a supplier's viewpoint. The AMTA article lists microwaves, hot plates, slow cookers, ovens and heating pads as inappropriate for heating stones. The sources do not say how common improvised heating was, and neither source gives data on how widely the method is now practiced.

Names in use

Sources use several labels for related procedures: 'hot stone massage', 'hot-stone massage therapy', 'heat-stone massage' and 'stone massage'. A Chinese trial protocol uses 'heat-stone massage' for a standardized hospital procedure, and its authors explain it within Chinese medicine theory, in which they say heat nourishes the meridians and the stone stimulates acupoints. LaStone Therapy is the name of one branded method credited to Nelson, and it is not a synonym for every hot stone massage.

Basalt is the stone most often named. The National University of Health Sciences patient page describes it as an iron-rich rock that holds heat, and it says stones are usually smooth river stones heated in water.

Terms that overlap but differ

A 2017 case report uses 'hot stone therapy' for a traditional Thai postpartum practice in which a heated stone is pressed on the body, and a 2020 Malaysian survey groups 'hot stone compression' with massage, reflexology and body wrapping. These are different procedures from a massage session in which a trained practitioner works with stones, and findings or hazards reported for one should not be assumed for another.

Two 2024 to 2025 orthopedic trials compared 'slow-stroke back massage' with hot stone massage, which shows that hot stone massage is treated in research as one massage form among several.

Elements of a session as described by practitioners

The National University of Health Sciences page says stones are heated in water and may be placed on the back, in the palms or between the toes, and that the warmth lets a therapist use deeper pressure if the client wants it. It adds that some therapists place stones on points they regard as energy centers, which it presents as a practice and not as an established fact. Nelson's AMTA article describes using stones within Swedish massage or placing them on the body, with a sheet, towel or clothing between skin and stone.

The same article advises a detailed intake form covering injuries, medications and other treatments, hydration before, during and after a session, and repeated checks with the client about temperature. It also describes alternating hot and cold stones in some treatments. These are one practitioner's recommendations and no study is cited for them.

Equipment and temperature in practitioner guidance

Nelson's article gives 110 to 130 degrees Fahrenheit as the water temperature for heating stones, recommends a professional stone heater with temperature control and a calibrated thermometer, and says it can take about three to four minutes for a client to judge whether a stone is too hot. It suggests holding a stone for a count of five seconds as a check. The figures are the author's guidance and not tested thresholds, and other sources use other ranges.

Procedures used in research

In a trial of hemodialysis patients, basalt stones were kept in water at 49 to 55 degrees Celsius for about an hour, covered with towels, and placed for ten minutes on points the authors call chakra points, followed by a 20-minute back massage, in 12 sessions over four weeks. A Chinese trial protocol specifies a stone heated to 45 to 50 degrees Celsius, pressed and moved for 15 minutes and followed by 15 minutes of massage, three times a week for two weeks, delivered by nurses with at least five years in chronic pain management.

Two orthopedic trials gave 10 to 15 minutes of hot stone massage twice on the first or second day after surgery. These are trial protocols and do not describe typical spa sessions, which differ in length, temperature and setting.

Uses described by educators and practitioners

The university patient page says the warmth relaxes muscle, and describes circulation and calming of the nervous system as effects, without citing studies. It suggests the method for people who often feel chilled and for people with muscle tension who prefer lighter pressure. Nelson's AMTA article suggests uses including sprains, strains, acute bursitis, tennis elbow, headaches and bruises, again with no studies cited. These are practitioner and educator claims and have not been tested in the research found for this page.

Postpartum and traditional contexts

In a cross-sectional survey of 725 postpartum mothers at a Malaysian primary care clinic, 85.5% used complementary medicine, and manipulative body therapies including massage, reflexology, hot stone compression and body wrapping were the most widely used (84.1%). The survey does not separate hot stone use from the other therapies grouped with it.

The Thai case report describes a belief that reheating the body in the postpartum period helps the uterus return to its former state and helps perineal tears recover, and a patient who applied the same idea to a prolapsed uterus. These are beliefs within a traditional setting, reported by the authors as background, and the report does not test them.

Search scope

A PubMed search for hot stone massage on 11 October 2026 returned nine records. Three were randomized trials of hot stone massage, two were small physiological studies of skin temperature, and the rest were a survey, a stone-needle history, a regional clinical report and a magazine item. A second PubMed search combining hot stones with burn, adverse event, injury or complication returned the same trials and no systematic review. Searches of Europe PMC added a trial protocol and one case report. No systematic review specific to hot stone massage was found, and databases other than PubMed and Europe PMC were not searched.

Randomized trials

A trial in Iran randomized 60 men on maintenance hemodialysis to 12 hot stone massage sessions over four weeks or usual care. Using the Pittsburgh Sleep Quality Index, completed before and one month after the intervention, the authors report that global scores improved in the massage group and worsened in the control group (P below .001). The authors list limits: one hospital, men only, a small sample, self-reported scores, and no placebo comparator. The values given in the abstract and in the tables differ slightly.

Two reports from a group in Iran describe 99 orthopedic surgery patients assigned to slow-stroke back massage, hot stone massage or routine care, with two short sessions on the first or second day after surgery. The abstracts report lower anxiety (Spielberger inventory, measured 30 minutes after the intervention) and better sleep quality scores than routine care. They do not say whether hot stone massage differed from slow-stroke massage, and the two abstracts do not state whether they share one sample.

Physiological studies and a planned trial

A thermography study of 40 healthy men found a rise in surface temperature at the back of the pectoral girdle and trunk after hot stone massage, with differences of 2 to 6% after heat-based treatments. In 25 female students, hot stones applied to three abdominal sites for nine minutes raised distal foot skin temperature, while one site did not. These studies measured skin temperature, not blood flow in disease, pain or other clinical outcomes.

A 2023 protocol describes a planned multicenter trial in China of 120 adults with chronic musculoskeletal pain, comparing heat-stone massage with a flurbiprofen plaster over two weeks. The protocol notes that participants and therapists cannot be blinded. No published results were found in the searches run for this page.

What the evidence does not establish

None of the trial records reviewed compared hot stone massage with the same massage using unheated stones, so effects of heat cannot be separated from touch, attention and expectation. The trials studied particular groups, for example hemodialysis patients and people soon after orthopedic surgery, over short follow-up periods. NCCIH summaries of massage in general describe weak or short-term evidence for several pain conditions and do not mention hot stones, so those findings should not be carried over to this method.

Burn cautions in practitioner guidance

Nelson's AMTA article names four situations behind burns: clients not feeling able to speak up about heat, missing information on intake forms, improper heating methods or devices, and too little material between hot stones and skin. It advises 'less time, less temperature' when a case is uncertain. The article does not state how often burns occur and cites no studies.

The same article lists diabetes, cancer, autoimmune dysfunction, epilepsy, neuropathy, heart disease, skin conditions, recent surgery and pregnancy as contraindications, noting that the list is not exhaustive. As retrieved, it does not explain the reason for each entry, so the link between these conditions and reduced sensation or circulation is not set out in the source.

Harms reported in research

The Chinese trial protocol expects burns, bruising and excessive sweating to be likely adverse events from heat and pressure, and its exclusion criteria cover cardiovascular disease, diabetes, peripheral nerve perception disorder and pregnancy. The hemodialysis trial excluded people with fractures, infections or skin disorders on the back and placed a towel between stone and skin. These are trial eligibility rules and not clinical guidance, and none of the trial reports reviewed gave a count of adverse events.

A 2017 case report describes a 72-year-old woman with stage IV uterine prolapse who pressed a heated stone onto the prolapsed uterus as self-treatment, based on a traditional postpartum belief. The uterus was burned and became infected, which the authors linked partly to poorly controlled diabetes, and she later had a hysterectomy. This was self-treatment and not a massage session. No case report of a burn during a professional stone massage was found, which does not show that none occur.

Suitability, training and care boundaries

NCCIH describes the risk of harm from massage generally as low, with rare serious events such as blood clots, nerve injury and fracture, often linked to vigorous massage or to people at higher risk of injury. It does not discuss heat. The sources reviewed give no quantified harm rates for hot stone massage, and the skin temperature studies do not address circulation in people with vascular or nerve disease.

Nelson's article advises learning hydrotherapy basics and client health assessment, but the sources reviewed describe no hot-stone-specific professional register or training standard, and no statutory regulation was looked for here. Massage does not replace assessment of new, persistent or worsening symptoms, and people with the conditions above can raise them with their clinician and practitioner before a session.
