About Floating

Floating is a wonderful way to reach deep relaxation, ease pain, and tap your full creative potential. We’re excited about the possibilities and can’t wait to bring floating back to Boston!

Other names for float tanks include isolation tanks, sensory deprivation tanks, and R.E.S.T. – which stands for Restricted Environmental Stimulation Therapy (or Technique). They all involve floating in ten to twelve inches of warm water semi-saturated with Epsom salt — 800 lbs to a tank! The Epsom salts increase the density of the water to greater than the Dead Sea, allowing you to float effortlessly — easily keeping your nose and mouth above the waterline.

We hope to bring a commercial float center back to Boston area, after too long an absence. But many things need to occur first — we’re still in the planning stages.

Introduction to Floating

“Float Nation”, teaser trailer for a 2013 documentary about various float experiences. “Sixty minutes of relaxation, pain free. And for someone who lives with pain every single day, every minute – that’s priceless.”

“Seeking serenity? Flotation therapy offers an inexpensive way to achieve it,” Washington Post, Sep 23rd, 2013.  “I didn’t just feel relaxed, I felt like the giant baby at the end of Stanley Kubrick’s ‘2001: A Space Odyssey’.”

“Embracing the Void: the profound, ecstatic state of nothingness I achieved while floating naked in a sensory deprivation tank”, Slate, May 13th 2013. “I emerged in a profound daze. I spoke slowly and quietly, like a smooth-jazz DJ, to the person at the spa desk who inquired how my session had gone. I felt more rested than if I’d slept for 16 hours on a pile of tranquilized chinchillas.”

“Postcards From the Edge of Consciousness”, Nautilus, Aug 14th 2014. “The only way I can describe it is that floating feels like being meditated. As if the tank does it for you, from the outside in.”

“After the post about sensory deprivation tanks, I thought I’d let you guys in on my experiences with them,” photo essay by imgur user iLikeCoffeeAndKittens, Feb 7th, 2014.  “The more you go, the easier it gets to get to that state of meditation that you will hallucinate more and sooner. But don’t expect anything crazy. You’ll probably see weird colors. I personally hear a lot of different tones and muffled voices. It’s actually pretty cool.”

Time Out: The Rise of Sensory Deprivation Tanks“, The Atlantic, Oct 12, 2012. “To experience complete sensory deprivation is, ideally, to delve into one’s psyche. It forces contemplation of facets of life, that — similar to less ‘heavy’ types of meditation — is meant to leave us healthier and happier.”

“The Nothing Eaters”, Portland Mercury, Feb 2nd, 2012.  “Additionally, I begin to write creatively for the first time in months, but with an uninhibited ease that I haven’t experienced in almost five years. In short, I was astounded by the changes I saw in myself.”

Why nothing really matters (my trip inside an isolation tank). “The way you phys­i­cally feel after­wards is like get­ting a mas­sage, doing a full work­out, and get­ting 8 hours of sleep all at once… Until you try it, you won’t under­stand what I’m talk­ing about.”  Posted March 28th, 2012.

“In the Tank”, The Nation, Oct 14, 2013.  “Some of sensory deprivation’s sublime attraction seems to lie in the way it fortifies the floater against the perceived harm of twenty-first-century culture.”

Science & Medicine

“Much Needed REST: The world of sensory deprivation tanks”, Psychology Tomorrow, Aug 2014.  “Lilly, Suedfeld, Borrie, and other researchers in the field published dozens of studies that concluded REST could be beneficial in countless ways: improving memory, increasing hand-eye coordination, even reducing spasticity in sufferers of cerebral palsy.”

Fibromyalgia Flotation Project. Have you been diagnosed with fibromyalgia? Consider participating in the non-floating control group while waiting for our center to open.

Rod Borrie, The Fibromyalgia Flotation Project, 31:35. An investigator talks about the disease, his research, and the project results.  “Without exception, the immediate intervention effects (average pre-post change) are highly significant [improvements] for all variables.”  Slide set.

David Manfield, Post-traumatic Stress Disorder (PTSD), 18:38.  There are no published controlled studies on flotation REST and PTSD specifically.  PTSD is a stress disorder notable for elevations in cortisol, ACTH and epinephrine; research on flotation clearly shows it can reduce all of these. Slide set.

Sensory Deprivation Boosts Musicians’ Skill Level“, Pacific Standard, May 16, 2011. Half of a university-level jazz improvization class does a month of floating, and has significantly greater performance improvement.

“Meditation’s positive residual effects”, Harvard Gazette, Nov 13, 2012. “These results are consistent with the overarching hypothesis that meditation may result in enduring, beneficial changes in brain function, especially in the area of emotional processing.”

“Mid-life stress ‘precedes dementia'”, BBC News, Sep 30, 2013. “In a study of 800 Swedish women, those who had to cope with events such as divorce or bereavement were more likely to get Alzheimer’s decades later. … The study authors say stress hormones may be to blame, triggering harmful alterations in the brain.”

“How does meditation change the brain?”, Scientific American, Oct 30, 2013. “Although areas of the brain responsible for sustaining attention usually shrink as we age, meditation counteracts this decay.”  The relationship between meditation and REST is virtually unstudied, but anecdotally many people expect there to be similarities.

“Like Valium and Oxycontin, without the Side Effects,” Scientific American, Oct 14, 2014.  “A Buddhist monk—this one with a doctorate in cell biology—has teamed with two prominent neuroscientists to present the latest findings on what meditation does to the brain and how those changes to neural circuits have some of the trappings of what might be labeled a perfect drug—Prozac-like muting of depression symptoms or prophylaxis against PTSD (just two on the list).”  

“The Emergence of Contemplative Neuroscience,” Richard Davidson, Meng Wu Lecture, Oct 29, 2012. (video, 1h36m).  Compassion meditation vs mindfulness practices, history of research, impacts on brain activity and gene expression, and investigations with children.

“Lupus and Flotation Therapy,” What is Flotation? Oct 3, 2014.  There’s no published research, but the benefits of floating match well with the symptoms and pain of lupus.


Spiritual Development

“FLOAT TANKS: The Lilly Path to Freedom (Part I ~ Experience, Part II ~ History, Part III ~ Benefits)”, Hyperborean Health, Oct 23, 2014.  “Learning how sit still and meditate has ironically been the biggest challenge of all. It turns out that besides the ambitious goal of spiritual enlightenment, meditation is simply good for our over active, reason-stuffed minds. My own personal best breakthrough as an adult came after a ten-day silent Vipassana retreat. But that was back in 2011. I needed a practice that I could do without becoming a temporary acetic or going nuts. Something gentle that I could fit into my daily life.”

“We had a Zen master who visited my lab once, and he asked to go in the tank for an hour. Most of his life he had meditated every day for four or five hours or more. And he thought the depth of meditation he reached in the tank was on par with a level he reached maybe once a year in his normal meditation environment—which was not exactly the middle of Times Square. He was amazed.” – Peter Suedfeld

“Why Yogis Should Try Isolation Tanks”, My Yoga Online, Sep 16, 2013. “Pratyahara [withdrawal of the senses] is considered by BKS Iyengar to be the ‘hinge’ or pivotal point in the yogic journey, because it is the step where we move from our behaviors and action in the outside world, to diving deep within in order to ‘gain knowledge of the self’.”

“Floating into Hoop Flow”, Oct 11, 2013.  Katelyn Selanders lost touch with her art, and got it back in the tank.  “As she continued to float, the feeling of Hoop Joy swept over her, that magic energy you feel when the hoop beats rhythmically across your core, when you shoot it off your body up into the sky like a shooting star, and when you break the hoop against the beat and don’t know or care what your next move is going to be. Without even being aware of it, she had floated back into her flow.”

“Float Tanks: Gateway to Infinite Being,” Jul 28, 2014.  “Being freed from the gravitas of gravity and allowing the nervous system to switch from the sympathetic to the parasympathetic state, the body can now focus on regeneration … No matter what your particular physical or emotional or mental issue is, this state is the one you want to be in to begin to heal it. And, in my opinion, floating is the quickest and safest way to get you there.”

On the train, I wasn’t angry and stressed. I didn’t listen to music to distract myself. My head maintained a soft buzz. I had a doctor’s appointment, so I got off at Sixth Avenue and 14th Street and walked west at dusk. These kinds of nights are rare but there was a pleasant glow in the sky, the kind that manifests itself on Instagram in photos of our glorious skyline, reds and yellows and sharp blue.”
