Deep tissue massage releases tension in muscles by applying slow strokes, direct pressure and friction across the grain of muscles. When you go in for a deep tissue massage, your masseuse will stroke your body to detect stiff or painful areas and determine the texture of the deep layers of your muscle. He or she then will work those areas will specific hand positions and strokes to provide you with the most relief. When you receive a deep tissue massage, cellular debris and toxins in the body are released, thus strengthening your immune system. This type of massage improves circulation by increasing oxygen flow throughout your body. In particular, deep tissue massage improves circulation to the feet.
