1. Alleviate Anxiety
In conventional medicine, double-blind, placebo-controlled studies are the gold standard. But massage and most other forms of bodywork don’t lend themselves well to such studies. Therefore, scientific “proof,” both for massage’s efficacy and its means of function, runs a little thin. But convincing clinical evidence is accumulating.
For example, in 2004, Christopher Moyer, PhD, a psychologist at the University of Wisconsin–Stout, published a meta-analysis on massage therapy research and found that, on average, research subjects who received massage had a lower level of anxiety than those who did not.
“My research consistently finds that massage does have an impact on anxiety,” says Moyer. “We don’t know exactly why, but people who get massage have less anxiety afterward.”
One popular explanation is that massage lowers the body’s levels of cortisol, the hormone notorious for triggering the body’s fight-or-flight response. “No matter how we measure cortisol — in saliva or urine — or how often, we always find that massage has a beneficial effect,” says Tiffany Field, PhD, a researcher at the Touch Research Institute at the University of Miami’s Miller School of Medicine.
Although Moyer is yet to be convinced of the cortisol connection, both he and Field agree that massage is potentially very therapeutic for what’s known as “state” anxiety. Unlike generalized anxiety disorders, state anxiety is a reaction to something you can pinpoint, such as a troubling or traumatic event, circumstance, or setting.
Although more research is needed, says Moyer, “some experts posit that the reported alleviation of state anxiety could be a result of something as simple as the social and psychological environment where massage takes place.”
2. Relieve Lower-Back Pain
Aside from stress, if there’s one thing that drives people to the massage table in droves, it’s pain. Especially lower-back pain, which up to 85 percent of Americans experience at some point during their lives.
In 2008, the Cochrane Collaboration (a global, independent, nonprofit organization that reviews the usefulness of healthcare interventions) published an examination of the evidence linking massage to relieving lower-back pain. Reviewing 13 clinical trials, they found massage to be a promising treatment.
“Physical pain is like the alarm system of a house,” says Andrea Furlan, PhD, a clinical epidemiologist who specializes in massage at the Institute for Work & Health in Toronto. “With acute pain, like a burn or a broken bone, the pain signal indicates something is wrong. But, if you have pain every day, like chronic back pain, the alarm is malfunctioning. Massage may not be able to turn off the alarm, but it can lower the volume.”
Theories abound on how massage interrupts the body’s pain loop. One of the oldest and most well-regarded explanations is called the gate-control theory. Proponents surmise that pain signals to the brain are muffled by competing stimuli. More specifically, pain travels on small-diameter nerve fibers, while massage stimulates large-diameter ones. Larger nerve fibers relay messages to the brain faster than smaller ones. In essence, says Furlan, the sensation of the massage “wins” over the sensation of pain.
One word of advice from fitness experts, though: You’ll get more lasting, long-term relief of lower-back pain by supplementing massage with isometric core exercises, such as planks, that focus on strengthening the muscles that support and guide the spine’s movements.
3. Soothe Tension Headaches
Tension leads to headaches, so it follows that massage would help ease them. And for many, trigger-point therapy can prove particularly effective.
“A trigger point is an area of tightly contracted muscle tissue,” says Albert Moraska, PhD, a researcher focused on complementary medicine at the University of Colorado in Denver. “Trigger points in the shoulder and neck refer [relay] pain to the head. By reducing the activity of trigger points, we can reduce headaches.”
Moraska’s work, funded by the National Center for Complementary and Alternative Medicine, explores how massaging the neck and shoulders can ease tension-type headaches. “We think massage can disrupt trigger points by forcing apart the tightly contracted sarcomeres (proteins responsible for contraction) within the muscle cells; as a result, the cells relax and subsequently muscle tension dissipates.”
4. Restore Deep Sleep
Roughly one in five Americans suffers from sleep deprivation, according to the American Academy of Sleep Medicine. That’s a problem, because lack of sleep alters the body’s biochemistry, making it more vulnerable to inflammation and lowered immunity, and more sensitive to pain.
“The relationship between pain and sleep deprivation is a vicious cycle,” says Tiffany Field. “Your body doesn’t get the rest it needs to heal.”
Although studies of massage therapy and sleep quality are few, the findings suggest that massage can promote deeper, less disturbed sleep, especially in people with painful chronic conditions such as fibromyalgia. Massage therapy indirectly promotes good sleep by relieving pain and encouraging relaxation.
Because massage therapy stimulates the body’s parasympathetic “rest-and-relax” nervous system (the opposite of its sympathetic “fight-or-flight” response), it counters both physical and mental stresses — giving you a better shot at enjoying the sleep you need to repair tissue during the night and to cope better during the day.
5. Reduce Symptoms of Depression
It may seem surprising that physically manipulating the body can help counter a malady we associate with the brain. But, in his oft-cited 2004 review, Christopher Moyer found that depression is particularly responsive to massage.
The average research subject who received massage had a level of depression that was lower than 73 percent of those who did not. These findings are on par with more conventional approaches to treating depression, including psychotherapy.
Field’s research on depression shows that massage boosts the body’s natural levels of serotonin, a substance that works “much like Prozac” in the brain. Her studies show that massage also encourages the brain to release the neurotransmitter dopamine, a mood enhancer, as well as oxytocin, a hormone that generates feelings of contentment.
While the exact mechanisms are unclear, it seems evident that a good massage has a variety of positive psychological implications as well, from receiving nurturing touch from another person, anticipating that the experience will be beneficial, or feeling empathy from the therapist.
6. Lower Blood Pressure
Given how positively it affects the rest of the body and mind, and how well it moderates stress, it probably comes as no surprise that massage therapy can also benefit the heart — in part by reducing blood pressure. In his meta-analysis, Moyer found that massage significantly lowers blood pressure, at least temporarily.
He notes that the findings are consistent with the theory that massage can trigger the body’s parasympathetic nervous system, which helps prompt the body to return to biochemical balance and emotional ease after enduring a stressful event.
But perhaps the bigger takeaway here is that massage can help unlock the body’s healing potential not by any one means, but rather by many. As epidemiologist Andrea Furlan points out, “Well before drugs or surgical procedures were developed, people used massage to treat almost everything.” Still, today, she notes, “when we get hurt, our first instinct is to rub.”
