The main aim of this study was to reduce stress and consequently depression to children (age 6 to 9); a stress, which gave them problems linked to physiological perceptions (vomiting, sweat, shallow and frequent breaths, a sense of choking and muscle pain) and psychological disorders derived from either a sense of separation or social anxiety, excessive shyness, fear of new situations involving new people and new environments, etc. The children were divided into two groups of ten. One belonged to the middle-class native children, and it acted as a control group, the other to immigrant low-class families. We tried to raise their self-esteem by providing them physical exercises under the listening of music, since physical activity and music release neurotransmitters and endorphins, chemicals in the brain that relieve depression. The focus of the experiment was to link the activities controlled by the right as well as the left hemisphere.
