This study investigated the effects of dry flotation Restricted Environmental Stimulation (REST) on transient mood states as measured by the Profile of Mood States (POMS) and on absorption as measured by the Tellegen Absorption Scale (TAS). Thirty subjects were assigned to either a lighted REST condition (N=10), a light-free REST condition or a no treatment control condition (N=10). Experimental participants floated supine on a salt water filled bladder using dry flotation REST (Relaxation Dynamics, Boulder, CO) for six hours. Participants in the lighted REST condition wore Ganzfeld goggles while participants in the light free REST condition wore a sleeping mask. Pre-to post REST and 2 week follow-up results showed that participants exposed to dry flotation REST in the lighted condition had a significant decrease in absorption. No significant changes were found for participants in the light free REST or control condition. Participants in the light free condition reported a decrease in anger pre to post REST.
