In this Healthline Original Series, host Joanna Carpenter learns the benefits of flotation therapy. A flotation tank, also called an isolation tank or a sensory deprivation tank, is used for restricted environmental stimulation therapy (REST). It is a dark, soundproof tank that is filled with a foot or less of salt water.
