Improved circulation can enhance the delivery of oxygen and nutrients to muscle cells. As cellular health improves, tissues function more efficiently. More efficient functioning leads to the removal of waste products and may increase the absorption of excess fluids and reduce swelling in soft tissues. Massage therapy relaxes muscle tissue, which reduces painful contractions and spasms. Massage can also reduce nerve compression. 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.
