Massage therapy has a long history in cultures around the world. Today, people use many different types of massage therapy for a variety of health-related purposes. In the United States, massage therapy is often considered part of complementary and alternative medicine (CAM), although it does have some conventional uses. This fact sheet provides a general overview of massage therapy and suggests sources for additional information.
Introduction to massage therapy
- Scientific evidence on massage therapy is limited. Scientists are not yet certain what changes occur in the body during massage, whether they influence health, and, if so, how. The National Center for Complementary and Alternative Medicine (NCCAM) is sponsoring studies to answer these questions and identify the purposes for which massage may be most helpful.
- Massage therapy appears to have few serious risks if it is used appropriately and provided by a trained massage professional.
- Tell your health care providers about any complementary and alternative practices you use. Give them a full picture of what you do to manage your health. This will help ensure coordinated and safe care.
What is the history of massage therapy?
Massage therapy dates back thousands of years. References to massage appear in writings from ancient China, Japan, India, Arabic nations, Egypt, Greece (Hippocrates defined medicine as "the art of rubbing"), and Rome.
Massage became widely used in Europe during the Renaissance. In the 1850s, two American physicians who had studied in Sweden introduced massage therapy in the United States, where it became popular and was promoted for a variety of health purposes. With scientific and technological advances in medical treatment during the 1930s and 1940s, massage fell out of favor in the United States. Interest in massage revived in the 1970s, especially among athletes.
What are the health benefits of massage therapy?
According to the 2007 National Health Interview Survey, which included a comprehensive survey of CAM use by Americans, an estimated 18 million U.S. adults and 700,000 children had received massage therapy in the previous year.
People use massage for a variety of health-related purposes, including to relieve pain, rehabilitate sports injuries, reduce stress, increase relaxation, address anxiety and depression, and aid general wellness.

What is massage therapy, and what are the types of massage?
The term "massage therapy" encompasses many different techniques (see box for examples). In general, therapists press, rub, and otherwise manipulate the muscles and other soft tissues of the body. They most often use their hands and fingers, but may use their forearms, elbows, or feet.
Types of Massage Therapy: A Few Examples
In Swedish massage, the therapist uses long strokes, kneading, deep circular movements, vibration, and tapping. Sports massage is similar to Swedish massage, adapted specifically to the needs of athletes. Among the many other examples are deep tissue massage and trigger point massage, which focuses on myofascial trigger points -- muscle "knots" that are painful when pressed and can cause symptoms elsewhere in the body.
What do massage therapists do in treating patients?
Massage therapists work in a variety of settings, including private offices, hospitals, nursing homes, studios, and sport and fitness facilities. Some also travel to patients' homes or workplaces. They usually try to provide a calm, soothing environment.
Therapists usually ask new patients about symptoms, medical history, and desired results. They may also perform an evaluation through touch, to locate painful or tense areas and determine how much pressure to apply.
Typically, the patient lies on a table, either in loose-fitting clothing or undressed (covered with a sheet, except for the area being massaged). The therapist may use oil or lotion to reduce friction on the skin. Sometimes, people receive massage therapy while sitting in a chair. A massage session may be fairly brief, but may also last an hour or even longer.
How does massage therapy affect the body?
Although scientific research on massage therapy -- whether it works and, if so, how -- is limited, there is evidence that massage may benefit some patients. Conclusions generally cannot yet be drawn about its effectiveness for specific health conditions.
According to one analysis, however, research supports the general conclusion that massage therapy is effective. The studies included in the analysis suggest that a single session of massage therapy can reduce "state anxiety" (a reaction to a particular situation), blood pressure, and heart rate, and multiple sessions can reduce "trait anxiety" (general anxiety-proneness), depression, and pain. In addition, recent studies suggest that massage may benefit certain conditions, for example:
- A 2008 review of 13 clinical trials found evidence that massage might be useful for chronic low-back pain. Clinical practice guidelines issued in 2007 by the American Pain Society and the American College of Physicians recommend that physicians consider using certain CAM therapies, including massage (as well as acupuncture, chiropractic, progressive relaxation, and yoga), when patients with chronic low-back pain do not respond to conventional treatment.
- A multisite study of more than 300 hospice patients with advanced cancer concluded that massage may help to relieve pain and improve mood for these patients.
- A study of 64 patients with chronic neck pain found that therapeutic massage was more beneficial than a self-care book, in terms of improving function and relieving symptoms.
There are numerous theories about how massage therapy may affect the body. For example, the "gate control theory" suggests that massage may provide stimulation that helps to block pain signals sent to the brain. Other theories suggest that massage might stimulate the release of certain chemicals in the body, such as serotonin or endorphins, or cause beneficial mechanical changes in the body. However, additional studies are needed to test the various theories.
What are side effects and risks of massage therapy?
Massage therapy appears to have few serious risks - if it is performed by a properly trained therapist and if appropriate cautions are followed. The number of serious injuries reported is very small. Side effects of massage therapy may include temporary pain or discomfort, bruising, swelling, and a sensitivity or allergy to massage oils.
Cautions about massage therapy include the following:
- Vigorous massage should be avoided by people with bleeding disorders or low blood platelet counts, and by people taking blood-thinning medications such as warfarin.
- Massage should not be done in any area of the body with blood clots, fractures, open or healing wounds, skin infections, or weakened bones (such as from osteoporosis or cancer), or where there has been a recent surgery.
- Although massage therapy appears to be generally safe for cancer patients, they should consult their oncologist before having a massage that involves deep or intense pressure. Any direct pressure over a tumor usually is discouraged. Cancer patients should discuss any concerns about massage therapy with their oncologist.
- Pregnant women should consult their health care provider before using massage therapy.
Who provides massage therapy?
There are approximately 1,500 massage therapy schools and training programs in the United States. In addition to hands-on practice of massage techniques, students generally learn about the body and how it works, business practices, and ethics. Massage training programs generally are approved by a state board. Some may also be accredited by an independent agency, such as the Commission on Massage Therapy Accreditation (COMTA).
As of 2010, 43 states and the District of Columbia had laws regulating massage therapy. In some states, regulation is by town ordinance.
The National Certification Board for Therapeutic Massage and Bodywork certifies practitioners who pass a national examination. Increasingly, states that license massage therapists require them to have a minimum of 500 hours of training at an accredited institution, pass a national exam, meet specific continuing education requirements, and carry malpractice insurance.
In addition to massage therapists, health care providers such as chiropractors and physical therapists may have training in massage.

What are some other points to consider about massage therapy as complementary and alternative medicine?
- Do not use massage therapy to replace your regular medical care or as a reason to postpone seeing a health care provider about a medical problem.
- If you have a medical condition and are unsure whether massage therapy would be appropriate for you, discuss your concerns with your health care provider. Your health care provider may also be able to help you select a massage therapist. You might also look for published research articles on massage therapy for your condition.
- Before deciding to begin massage therapy, ask about the therapist's training, experience, and credentials. Also ask about the number of treatments that might be needed, the cost, and insurance coverage.
- If a massage therapist suggests using other CAM practices (for example, herbs or other supplements, or a special diet), discuss it first with your regular health care provider.
- Tell all your health care providers about any complementary and alternative practices you use. Give them a full picture of what you do to manage your health. This will ensure coordinated and safe care.
