Muscles have a greater purpose to our bodies other than just movement. When we encounter stressful situations, we transfer that stress and tension to our muscles as a way to cope with the given situation. This can be anywhere from everyday work/family-related stress, to traumatic events such as a car accident or death of a person to whom you were close to. "Massage reduces the muscular tension used to suppress emotion and so can lead to emotional release," stated by Anne Williams.
With a holistic approach, massages are a great way to reconnect our bodies with our mind and soul. It is important to treat the source of the problem rather than mask the symptoms. Pain is a secondary reaction that is meant to grab our attention so that we may fix what is wrong, the trick is finding the source which may not necessarily be physiological, but rather psychological.
