Patients with depression can self-help through self-adjustment or seek help from a doctor. Clinically, the method of self-adjustment mainly involves exercise, which is also called behavioral activation training in psychology. Exercise can relax the muscles throughout the body. Additionally, exercise can stimulate the brain to release the "happiness element" endorphins, which have a significant improving effect on depression and anxiety. Other methods include venting and shifting attention. Venting typically involves expressing feelings through spoken or written words to others, especially close friends and family. By expressing these feelings, depressive emotions can also be articulated. Shifting attention, clinically, involves engaging in personal interests such as painting, fishing, or listening to music, which can increase pleasure and enhance motivation. Alternatively, seeking help from a doctor usually involves psychotherapy and medication, which often yield good results.
