For thousands of years, the power of touch has been considered an important part of the healing process for people suffering from a wide variety of ailments all over the world. One of the most popular of these therapies is massage, the manipulation of the muscles and soft tissues of the body.

Some may consider massage a relaxing indulgence meant only for pampering, but today, modern medicine recognizes that it actually has physical, emotional, and mental health benefits. According to the National Institutes of Health, there are more than 80 different types of massage, including Swedish (widely considered the most popular), shiatsu, deep-tissue, and sports massage. When provided by a trained professional, this bodywork can have therapeutic effects all over the body for everyone from cancer patients and pregnant women to weekend athletes and those of us who just need to relax.

The American Massage Therapy Association® estimates that roughly one in six adults—or 39 million Americans—had at least one massage in 2006. And the use of massage continues to grow as its benefits become even clearer.

Here are some of the major ways massage helps rejuvenate and heal our bodies and minds:

Relieve pain.

Massage stimulates the release of endorphins, the body's natural painkillers, to alleviate the soreness, aches, and pains associated with everything from chronic conditions such as arthritis to general joint and muscle pain.

Improve circulation.

The rubbing and kneading motions of massage can increase blood flow throughout the body, with many benefits including reducing heart rate, lowering blood pressure, and relaxing muscles.

Enhance immune system.

Some studies show that massage stimulates an increase in the number of cells in the body that help protect us against illness and disease.

Rehabilitate.

Whether you're recovering from surgery or an injury, massage can reduce swelling, relieve muscle aches and stiffness, and improve range of motion to help you get back on your feet.

Reduce stress.

Not only does massage feel good, but it relaxes your body and your mind, fostering reduced anxiety and a general sense of well-being.
