Massage Therapy and Cortisol: Does a Massage Really Lower Your Stress Hormones?

Spa menus and wellness blogs often say a massage "flushes out cortisol" or lowers stress hormones by about a third. It is an appealing idea, because most people do feel calmer after a good massage. But feeling relaxed and having measurably lower cortisol are two different things, and the research on the second question is more complicated than the marketing suggests.

The "about a third" figure usually traces back to a 2005 review in the International Journal of Neuroscience by Tiffany Field and colleagues at the University of Miami's Touch Research Institute. Pooling studies largely from their own group, they reported that cortisol measured in saliva or urine fell by an average of about 31% after massage, alongside increases in serotonin and dopamine. That paper has been cited widely, and it is the main source behind many of the confident claims you see online.

A more independent look came in 2011, when psychologist Christopher Moyer and colleagues published a quantitative review in the Journal of Bodywork and Movement Therapies. They analyzed 18 studies covering roughly 700 people, using statistical methods that account for each study's size and design. Their conclusion was that massage's effect on cortisol was very small and not statistically meaningful in most studies, with one possible exception involving repeated sessions in children. The authors stated plainly that their findings did not support the common assertion that massage substantially reduces cortisol.

That does not mean massage does nothing. An earlier 2004 meta-analysis by Moyer's group in Psychological Bulletin found that massage was associated with reductions in anxiety and, over a course of sessions, in depression symptoms and some types of pain. A 2010 study by Mark Rapaport and colleagues at Cedars-Sinai, published in the Journal of Alternative and Complementary Medicine, compared a single 45-minute Swedish massage with light touch in healthy adults and found a clear drop in vasopressin, a hormone involved in the stress response, with only a small change in cortisol. The likely picture is that massage helps people feel better through several routes, such as the nervous system and pain signaling, rather than mainly by lowering cortisol.

Part of the confusion comes from how hard cortisol is to measure well. It follows a strong daily rhythm, peaking in the morning and falling through the day, so a reading taken after an afternoon massage may be lower simply because of the time. Lying still in a quiet room, the expectation of relaxation, and the stress of being in a study can all shift levels. Many massage trials are small and cannot hide from participants which treatment they received, which makes it hard to separate the massage itself from the overall experience.

So what is proven and what is trend? Reasonably well supported: massage is associated with lower anxiety in the short term and can help some kinds of pain and mood symptoms over repeated sessions. Mixed and weak: the idea that massage reliably lowers cortisol, with the most careful analysis finding the effect very small. Trend and marketing: specific percentages, "cortisol flush" promises, and claims that a massage will fix stress-related skin problems, which have not been tested. If massage helps you unwind, it is a reasonable, low-risk part of a stress routine, as long as it is valued for how it makes you feel rather than for a hormone number.
