In psychology, relaxation is the emotional state of low tension, in which there is an absence of arousal that could come from sources such as anger, anxiety, or fear. Relaxation is a form of mild ecstasy coming from the frontal lobe of the brain in which the backward cortex sends signals to the frontal cortex via a mild sedative. Relaxation can be achieved through meditation, autogenics, and progressive muscle relaxation. Relaxation helps improve coping with stress.
