The Physiological Effects of Flotation REST

Abstract

There is an emerging research and clinical tool which may facilitate the exploration of interrelationships between mind and physiology. This tool is Restricted Environmental Stimulation Technique or (REST). This chapter will introduce you to the psychophysiological framework of REST by presenting some basic human research studies which we have performed over the past 10 years. There are several REST formats which have been investigated, with the two most common being chamber (room) REST and flotation REST. In the former, an individual is in solitude in a room with greatly limited external contact for an extended period (24 hours). In flotation REST, the individual lies supinely for 30–60 minutes in thermoneutral, buoyant fluid with minimal photic, auditory and tactile stimulation.
