Isolation tank

In order to reduce thermal sensations, the water in the float tank is maintained at approximately skin temperature, around 35 °C.

The pool design is housed in a room that is soundproof and lightproof, with tightly controlled ambient air temperature and humidity.

"[9][10] Flotation has been widely advertised as a form of alternative medicine that has a number of health benefits, but the claims are often exaggerated and poorly evidenced.

[8] Despite the lack of scientific support, people have sought treatment from flotation for many conditions including muscle tension, chronic pain, hypertension, and rheumatoid arthritis to PMS.

[11] A 2005 meta-analysis of clinical trials that had been conducted at that time, found that the trials were generally small and highly prone to error, but given that limitation, use of isolation tanks, (called "flotation REST" or "restricted environmental stimulation therapy" in the literature) shows a large effect size (Cohen's d = 1.02) for stress reduction.

Example of a float tank using a pod design
An open fiberglass float pool at the Laureate Institute for Brain Research in Tulsa , Oklahoma, USA allows subjects with clinical anxiety to float comfortably, without the apprehension one might encounter in an enclosed float environment.
