ScienceDaily (2007-11-06) — Relaxation in large, sound- and light-proof tanks with high-salt water — floating — is an effective way to alleviate long-term stress-related pain. Sleep was improved, patients felt more optimistic, and the content of the vitalizing hormone prolactin increased. Anxiety, stress, depression, and perception of pain declined.

Scientific research on the pain relief benefits of floatation tanks have been going on for decades. You can see a small sample of the research by clicking here. You can click here to watch a TV segment where my wife and I were interviewed when we ran a floatation center. Also interviewed was one of our regular customers who floated for relief from fibromyalgia. 

For me, floating put an end to 6 years of progressively debilitating back pain caused by a pinched nerve in my lower back. Little surprise then that I’m such a big fan!
