In psychology, relaxation is the emotional state of low tension, in which there is an absence of arousal, particularly from negative sources such as anger, anxiety, or fear. [2] 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.
Calmness can most easily occur for the average person during relaxation, but it can also be found during much more alert and aware states. [3] Some people find that focusing the mind on something external, such as studying, or internal, such as breathing, can be very calming.
Excessive stress and sleep deprivation can cause cardiovascular issues, such as high blood pressure and heart disease. In a study focusing on the impacts of chronic stress on the heart, it was found that during times of chronic stress, the body hyperactivates the sympathetic nervous system which leads to changes in heart rate variability.

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.
Thus, relaxation techniques are useful for either emotional pain caused by stress, anger, anxiety, and mood of depression, or chronic pain caused by strains, single-side muscle use, awkward position, restriction of movement in certain areas of the spine, improper form during physical activity, and stressful posture.

Electroencephalography has been used for meditation research.. The psychological and physiological effects of meditation have been studied. In recent years, studies of meditation have increasingly involved the use of modern instruments, such as functional magnetic resonance imaging and electroencephalography, which are able to observe brain physiology and neural activity in living subjects ...
Collins also sees the benefit of a device like this one for relaxation and stress reduction, stating "the Renpho mask can lower stress levels, which in turn benefits skin health by reducing flare ...
