Something in the world of floating have you stumped?
Show Highlights
The Parasympathetic Nervous System is the part of your body that gets really excited when the rest of your body is winding down. Taking care of the digestive and rest systems are an important part of human health and physiology. How do float tanks affect this system?
Many of the studies on floating have demonstrated an impact on the parasympathetic nervous system. Graham and Ashkahn talk about the information that’s been studied so far.

Transcription of this episode… (in case you prefer reading)
Graham: All right.
Ashkahn: Welcome.
Graham: Hello everybody.
Ashkahn: Yeah. This is Ashkahn.
Graham: I am Graham.
Ashkahn: We’re gonna answer a question today.
Graham: Which is, “have there been any studies that show floating engages the parasympathetic nervous system?” The old PNS.
Ashkahn: Yeah. Yeah. Yes.
Graham: Thank you for the question. Good luck finding them.
No, let’s start with what the parasympathetic nervous system is.
Ashkahn: Yeah. It’s not the sympathetic nervous system.
Graham: Bingo. Therein lies the entire story.
The sympathetic nervous system is generally much more active. It’s when your adrenal system activates. The parasympathetic nervous system is your rest and digest system, sometimes called.
Ashkahn: Yeah. The little phrases are fight or flight, versus rest and digest.
Graham: Yep. Parasympathetic is much more associated with things like digestion, as you can imagine, with your heart rate slowing, breathing slowing.
Ashkahn: Resting.
Graham: All these things, if you’re familiar with floating, which hopefully you are since you’re listening to us ramble on about it day after day.
Ashkahn: If not, welcome. It’s about to be really exciting to you.
Graham: Right, those are the activities we associate with floating. When you’re in the tank, your heart rate slows, your breathing slows, you calm down.
Ashkahn: People say they come out feeling very hungry sometimes.
Graham: It’s because you’re activating your parasympathetic nervous system. That’s what we’re talking about here.
Ashkahn: This is most likely a very simplified view of the entire thing, but I always think about it as our bodies react to the external environment. When there’s stuff you have to do or there’s an animal trying to eat you, or all the stuff that generally comes with staying alive, your body has to prioritize resources.
Graham: Yeah.
Ashkahn: If a bear is chasing you, your body is like, “You know what we should be doing right now is digesting food.” It allocates the resources it needs to deal with the much more important stuff that’s happening, and then when you don’t have things like that going on, your body shifts into another mode. It’s like, “Great, now we have time to do maintenance stuff. Let’s repair things, let’s rest, let’s grow.” Part of human growth can be part of the rest and digest system.
I think there’s very acute cases of children, of huge amounts of stress in their childhood actually being stunted in terms of their growth. All this stuff is our body switching the fire hose of resources around.
Graham: Yeah. As far as studies showing that that’s the system that’s being activated, for any study that actually looks at humanmetrics and is measuring heart rate, is measuring our brain wave levels even, or what’s going on to us physically in the tank, you’d be hard pressed to find any of those studies that don’t point to the parasympathetic nervous system being activated.
Ashkahn: Yeah. Like most of the stuff you hear about in terms of research, of cortisol levels, and heart rate, and blood pressure, and-
Graham: Breathing.
Ashkahn: Breathing. All these sorts of things are those kinds of effect, the effects of your body switching gears like that.
Graham: I’ll turn the question around to you listener and say, “Do you know of any studies that don’t show the parasympathetic nervous system being activated, that are focusing on humanmetrics.” ‘Cause I would say, “I can’t think of any.”
Ashkahn: Yeah. It seems like it’s just a big broad category of things that our body does, and almost everything is showing, I think that’s probably one of the symptoms of an overabundance of stress in our society, is that our bodies don’t have as much time to be in the parasympathetic nervous system mode as we used to. We used to have longer periods of activating that, and that just gets a little bit harder in modern society with cars, and blinking lights, and sound effects, and all that sort of stuff that our bodies interpret sometimes as things they need to respond to, and things they need to respond to with more of our active survival instincts.
Graham: Yeah. I remember having a discussion with Glenn Perry at some point, one of the founders of our industry, and owners of some Samadhi Tank Company. He was saying, it wasn’t that long ago where we’d finish up a day of work, and then maybe we’d sit on our porch and watch the sunset, and think about things that we done during the day. Maybe we’d reflect and say, “Oh, you know, I was a little too mean in that scenario.” Or, “Oh, my calf hurts. Maybe I should take it a little easy there.” It’s true, we’re a society of chronic stress these days. We don’t have that down time. To me, the fact that the float tanks do activate the parasympathetic nervous system, they, as Glen Perry was saying, recreate this end of the day relaxation contemplation that we used to get very naturally, is a lot of their benefit. It’s certainly at least for me, one of the big things that I take away from floating, is forcing that rest and digest system back into my busy life.
Of those, I guess just to name some, I would say the early ones like John Turner, Tom Fine, they took some really detailed metrics the best that they could do for the time when they were running research back in the ’80s, up through the ’90s. They’re some of the people whose early findings are showing this parasympathetic nervous system activating. More recently, Justin Feinstein has just been collecting a bunch of data on biological metrics and marking. Just to kick you off, those are two big ones. But I think Anette Kjellgren over in Sweden, and the Swedish researchers have also shown the same results. Again, any study that you’re looking into where it’s focusing on this biological aspect of floating, you’re probably find that same parasympathetic nervous system activation.
Question answered, I guess?
Ashkahn: Yeah. Yeah, I guess we did it. We only know so much about the technicalities of all this stuff. The same with that we’re not lawyers, or doctors, or economists. We’re also not researchers. I feel pretty good about the broad strokes of how all this stuff works, but I’m pretty sure there’s plenty of nuance too, to the human body.
Graham: I’ve never found that to be true, but if you disagree, go over to FloatTankSolutions.com/podcast and shoot in your own questions so we can embarrass ourselves with that analogy.
Ashkahn: Yeah. Please.
Graham: It’s what we live for.
Ashkahn: All right. Bye everybody.
Graham: Thanks.

Why Do Float Centers use Child Sized Earplugs? – DSP 245
When shopping around for earplugs for float tanks, there’s only a few that actually work well in the float solution. One of these is the Mack’s wax earplugs, basically the standard for swimmers as well. But why do so many float centers buy the child sized ones when stocking their float center?
Ashkahn “Big Ears” Jahromi let’s all of us know what he thinks is going on and that many people may be using these earplugs incorrectly. Graham “Normal Ears” Talley, backs him up with some facts and important reminders.
What Causes that Float Tank Twitch? – DSP 244
Graham and Ashkahn discuss what causes that mysterious twitch people sometimes experience in the float tank, called the hypnic jerk (AKA hypnagogic jerk, sleep start, sleep twitch, myoclonic jerk, or night start ). While the guys offer up some interesting theories, there’s not a lot of research that’s been done on what causes these, so we’re left with theories, more or less.
Ashkahn thinks it has to do with pancakes.
Getting Salty With Speakers – Professor Hu – DSP 242
Dr. Peicheng Hu is a researcher from China that studies floatation therapy over there. He’s speaking at the Float Conference this year so Ashkahn decided to take the opportunity to talk to him about the Chinese float industry and some of the differences in the practice as well as the type of research being done out there.
Are Google Ads Important – DSP 241
When looking at online marketing, Google Ads seem like an obvious choice, but are as relevant for Float Centers as they are for other businesses? The most useful thing these ads do is boost search result placement, but if the ads are to boost the ranking of a float center that is the only center in town, it’s not going to affect search results much.
Derek and Graham dissect the platform and really focus in on the uses (or lack thereof) of Google Ads for float centers and provide tools and tips for online marketing and how to make it as effective as possible.
How to Build Community Relationships from Home – DSP 240
Building community relationships when you’re already working 12 hour days at your float center can seem impossible. How do you make those connections when you’re busy during business hours?
Derek and Graham tackle this problem and focus on it from personal experience. When Float On was just starting up, Graham was always running around, but still found time to grab a tea with local wellness professionals in his down time just to chat and hang out. Derek also points out that there’s plenty of social media tools that you can use between transitions when you have a couple minutes.

Fancy Acronyms for your Business Plan: TAM, SAM, and SOM
In this post, we’ll be looking at those enigmatic acronyms: TAM, SAM, and SOM, which are the backbone for the market analysis section of your written plan. We’ve helped a couple hundred float centers to develop their business plans, and we’ve found that this one area generates the most questions, and seems to generally be the most difficult to wrap your head around.

The Float Tour makes a stop in Tulsa, OK to visit Dr. Justin Feinstein’s Float Clinic and Research Center at the Laureate Institute of Brain Research (LIBR).
Rather than following the usual path of incremental progress with its research, LIBR is tasked with pursuing alternative treatments that have a chance of “shooting the moon” and making potentially large leaps in medical progress. Float tanks are just the kind of technology they’re looking to explore.
Float Tank Centers for Sale
On our journey we found at least three owners who are actively looking to sell their float tank centers, and in all three cases the centers are doing well. Life often calls us in different directions than we expect.
In case you’re in the market for a pre-established business, without all the trials and tribulations of starting from scratch, here’s information on two centers that are, for the moment, available to swoop in on…
The Float Tour Blog – Issue #8
The desert is vast and the sun is harsh, but it doesn’t deter floating. We’re officially off the beaten path. From here, the float centers have become a bit more spread out. Everywhere we go, however, the people continue to be kind and eager to see us.
Everything in between Arizona and Texas is nestled in between some of the major manufacturers in the United States, providing some resources that other areas just don’t have. Areas that might find building out a center prohibitively expensive due to additional shipping costs, not to mention that real estate is cheaper than in major metropolitan areas, can save a bit of money when planning their buildout.
