Neurohormonal Effects of Massage Therapy
Massage tends to elevate the levels of dopamine, a neurohormone released by the hypothalamus. Dopamine influences fine motor activity like painting or playing a musical instrument. It affects intuition, inspiration, joy, and enthusiasm. Those lacking in dopamine will likely exhibit clumsiness, poor focus, and be easily distracted.
Massage can also raise the availability of serotonin, a neurohormone that regulates behavior in terms of emotions, acting to quell irritability and cravings for sex and food. Those low in serotonin often have difficulty sleeping and tend to suffer from depression and obsessive-compulsive disorders.
Research has shown that massage can achieve a number of positive results. For example, a 15 minute seated massage can elevate epinephrine (adrenaline) levels by stimulating the sympathetic nervous system. This can increase a person's alertness. A slower, longer, deeper, and more rhythmic massage can, on the other hand, reduce epinephrine levels, creating a feeling of relaxation, and facilitating deep sleep.
Acupressure and trigger point therapy (applying pressure to tender muscle tissue to relieve pain and dysfunction) are further examples of massage techniques that provide a number of important benefits. These techniques create endorphins, which are compounds known to reduce pain and produce a sense of euphoria.
Oxytocin is another neurohormone produced by massage therapy. It supports feelings of attachment and can help during pregnancy, birthing, and lactation. Massage therapy has also been shown to reduce levels of Cortisol -- the stress related neurohormone produced by the adrenal glands. Finally, by encouraging sleep, massage can increase the availability of growth hormones which promote cell division, and is involved in tissue repair, regeneration, and healing.
