It addresses both psychological and physiological effects of stress such as increased heart rate, sweating, and muscle tension. [2] There are many variations of relaxation techniques, including progressive muscle relaxation , autogenic training , guided imagery , biofeedback -assisted relaxation, and other techniques.
Stress is the leading cause of mental and physical problems, [citation needed] therefore feeling relaxed is often beneficial for a person's health. When a person is highly stressed, the sympathetic nervous system is activated because one is in a fight-or-flight response mode; over time, this could have negative effects on a human body .

[7] It is important to breathe throughout the entire exercise, [7] because some sources recommend breathing in while tensing the muscles and breathing out as the muscles are released. [7]
Experimentally, stress relaxation is determined by step strain experiments, i.e. by applying a sudden one-time strain and measuring the build-up and subsequent relaxation of stress in the material (see figure), in either extensional or shear rheology. a) Applied step strain and b) induced stress as functions of time for a viscoelastic material.
