Transcript for Project Wellness: Can Flotation Therapy Cure You?
look at the ultimate way to relax apparently floating. Everybody gets stressed out but this new treatment could be a way to feel your anxiety float a what and ABC's kayna Whitworth gave it a whirl. Reporter: It may be the ultimate way to totally chill out. Popular with celebs like Emma stone, minka Kelly and Sophia bush. Three actresses that love floating among others. Reporter: And Steph curry shows us how it's done on ESPN's hang time. It's an opportunity to just relax and get away from all the stresses on of the court and in life. Many physicians are also praising the practice. I'm a big proponent for anything that allows to us get out of our own mind. If we can turn off the thought process we have less anxiety, we'll have less stress and live healthier lives. Relaxing in a sensory deprivation tank, no gravity, no light, no noise. I had to give it a try. This is 11 inches of highly salted water so I should be able to float no matter what. I shouldn't have to force myself to float so you just kind of slide in. Okay, so before you know it you're floating and this is when your relaxation starts Jim Heffner owner of just float has seen a trend of clients coming in not just to relax but for a variety of health issues. Something about floating in water with no effort, it's nice and long, the spine and no pressure on your joints or body. A fair bit of research has been done on floating but is in its infancy. What it can do with people with severe depression. Reporter: Anne is one of those cases and started floating with help with stress and high blood pressure. Now that I've been float forego a year I'm off my blood pressure medication. My ability to manage the stress of day-to-day living is so much better from floating of the I can't imagine not doing it. Reporter: For "Good morning America," kayna Whitworth, ABC news, Los Angeles. All right. So many questions. Drop Jennifer Ashton is here. Is there any science on this and what is the science say? There is some science but as we heard in the piece it's really we need a lot more data and need rigorous scientific studies but they're studying it in the field of neuroscience using eegs or electrodes to measure brain activity and comparing functional mris to see if different areas of the brain light up, per se, particularly they're looking at it for anxiety and PTSD but as you heard maybe hypertension. I will say medically whenever you hear that something is good for everything, my medical cynic ears kind of poke up. But, again, risk/benefit, I don't think it's that risky. You just mentioned it doesn't seem that risky. Almost feels like meditation in water but doesn't seem like there could be many down sides. Are there any? The only downside if you were to pursue flotation as your sole treatment for something that requires standard, you know, and proven medical therapy. If you're going to add it, I'm always a big fan of adding not taking away or either/or, the true benefit of something complimentary, I think it could be fine. Cost would be a factor. Claustrophobia. I don't think there is a real risk of grounding because again that's the whole point of this buoyancy. Would you recommend it? I mean I would try it. As long as you're not claustrophobic because some are in tanks but the room we saw kayna in, better, go ahead and give it a shot. I think we'll learn more about it in the future. Who knew there was something call the an experienced floater. Who knew. It's right there on my business card. Dr. Ashton, I have to interrupt.
