Massage therapy relaxes muscle tissue, which reduces painful contractions and spasms. Massage can also reduce nerve tension. To understand this, consider that when muscles are contracted, they sometimes compress the nerves around them. When these muscles are relaxed, the nerves are no longer compressed, and, in theory, can get proper nutrients and operate more efficiently. The nerves can assume their normal work of transmitting messages to and from the brain, which improves functioning of the muscles and organs.
Touching the skin or applying pressure relaxes muscles, tendons, and ligaments. In addition, while some of the deeper tissues of the body, such as deep spinal musculature, cannot be easily accessed by a massage therapist, the release of more superficial layers of muscles may also affect these deeper layers. This can lead to both superficial and deep tissues finding a better alignment and balance.
Organs can also benefit from massage, as they share neurological pain pathways with muscles, bones, and nerves. When muscles, bones, or nerves are distressed, organs can sometimes reflect distress and dysfunction. For example, low back pain can intensify menstrual cramps and menstrual cramps can cause low back muscles to tense. Massage can therefore improve symptoms associated with the functioning of both the organ and the muscles.
