Restricted environmental stimulation therapy (REST or peceptual isolation therapy) is an intervention based around sensory deprivation i.e. minimizing sensory inputs such as sound, lights and smells.
The individual is placed in an environment with minimal distractions, such as a dimly lit room or isolation tank, for several hours or days at a time.
REST is designed to encourage an extremely deep level of relaxation.
