REST (Restricted Environmental Stimulation Technique)

Restricted Environmental Stimulation Technique (REST) is a relaxation method that involves limiting sensory input to the brain. Usually, individuals are placed in a comfortable, quiet environment—like a flotation tank filled with warm, buoyant water—reducing external stimuli such as light, sound, and touch. This minimal stimulation helps the brain relax deeply, often leading to meditative or altered states of consciousness. REST is used for stress relief, meditation, and personal insight, allowing individuals to experience a calm mental state by temporarily shutting out outside distractions.
