Sensory Deprivation

Other applications have grown out of research on altered states of consciousness produced by restricting sensory stimulation from the environment. Researchers in the 1950's completed extensive studies on the effects of prolonged sensory deprivation. Subjects placed in soundproof isolation chambers with translucent goggles to eliminate vision and padded arm tubes to minimize touch sensation often experienced negative psychological effects after about a day. Most subjects suffered from extreme boredom, slowed reaction time, and impaired problem-solving ability. Some subjects reacted to sensory deprivation by creating their own internally generated sights and sounds in the form of hallucinations. These results led to the institution of special procedures to help reduce the effects of sensory deprivation in certain occupations; for example, airline pilots on long night flights, astronauts living for prolonged periods in tiny space capsules, and individuals working in isolated weather stations. A controlled form of sensory deprivation, known as restricted environmental stimulation therapy (REST), has been used to reduce the effects of overarousal and hyperactivity. REST sessions usually involve floating in heavily salted warm water in a dark, soundproof tank. Most subjects find this floating sensation very pleasant, and there have been many reports of long-term reductions in high blood pressure and other stress-related problems.
