Sensory Deprivation Tanks, and Other Overblown Human Closets

Sensory deprivation tanks, oxygen therapy chambers and unbelievably cold saunas - oh my! These machines are used to reduce stress, ease pain and could be useful in doing that, but these machines are generally meant to be used in very specific situations.

I've done the flotation tank thing a couple of times. The claims by floating afficianados are extreme and some of them even bizarre but I can say this; it is relaxing and I've experienced some interesting sensations. I think it's especially nice for people who love the water in general like myself. It is a bit expensive but I think of it as a treat like getting myself a massage; an hour alone in the dark warm water where no one can bother me and I don't even have to hold up my own head because the water is doing it for me.

[@jenspeeters6250]

They would if they couldn't choose to leave the tank yeah

[@garethbaus5471]

It would probably depend on if they can leave the tank voluntarily.

[@1987seminole]

I love using sensory deprivation tanks! I have hallucinations and generally come out relaxed. I do it recreationaly and I have not heard anyone making bold or wild claims about miracle cures because of it.

[@hotsistersue]

I'm not expecting any kind of miracles, but I really want to try sensory deprivation. I can only imagine the amazing daydreaming I could accomplish in that thing!

[@MRquestionable10]

[@cellogirl11rw55]

I would love to try cryotherapy. My DBT therapist had me dunk my face in ice water whenever I'm having a hard time getting ahold of myself because it triggers something called the dive response, which is basically where your brain thinks your whole body is in a frigid body of water, like a glacial lake. So, your brain tells the nervous system to slow down and focus on keeping your core warm until someone saves you. I wonder if the response would be more profound in a cryotherapy tube.

[@Hanneth]

I used to sometimes kind of do it at our indoor pool. I live in a condo and there are times where there is no one else there and you can get virtually the same affect. Though I quite enjoyed watching the light reflect off the pool creating patterns on the ceiling instead of the darkness. There were times I would close my eyes and all there would be was the very soft sounds of the pool and I would just let my mind wonder.

[@callumleask1053]

I'm not surprised the cold mice gained weight, wouldn't you assume that they would naturally try to get a thicker layer to heat them to their natural temperature?

[@pyrethorn]

As someone with Panic and Anxiety Disorder, sensory dep tanks are really helpful. Perhaps it is a placebo effect, but going once or twice a month does a lot for my state of mind. From what myself and friends have experienced, it tends to put you into a near dreamlike state. If nothing else, it is super relaxing and a very safe place.

[@elderlyperson4583]

Sensory Deprivation Tanks are actually awesome, it causes you to feel very... different, and are very good for just thinking about things. Hyperbaric Chambers are really pointless in my experience. Cryotherapy works as far as I can tell but I've only done it a couple of times so it may have just been coincidence or the placebo effect. Bottom line, the only one I'd recommend doing is the Sensory Deprivation Tank just for the experience

[@Jondude201]

Sensory deprivation tanks might be overhyped but it made for one of the funniest GMM episodes ever so I approve of them.

[@eeryglo]

I can tell you that sensory deprivation tanks certainly dont cure autism! My mother was really afraid of my little brother being autistic, so ever since he was 6 months old, she would put him into a little sensory deprivation tank we got from ebay (Man, you can find a lot of bargains on that site!). And she did this for like 2 years before giving up. And wouldn't you know it, my brother ended up getting autism none-the-less! He is like 6 years now, and only communicates in hisses. We still love him, but we try to ignore him as best as we can, so that his symptoms doesn't worsen. Thanks for a good and informative video as per usual, SciShow!

[@hermanborgan5857]

what?? why did you think that would help??

[@stefangrujic3352]

eery what

[@Guru_1092]

You don't really "get" autism, as much as you are born with it. Either way, I'm just legitimately surprised that people believe in the idea that a neurological disorder in the development of the brain can be "cured".

[@eeryglo]

Why are you making a fuzz about this. Every time he made a racket all up in there, we opened it up and said "Dont even worry about it, it's going to be O.K." just to let him know not to worry about it, and that it was going to be O.K. We tried it because my mother read it might be a good idea in a magazine. And we were really afraid of autism.

[@timelesssky]

The oxygen therapy tanks were the ones that are supposed to help autism. I think you got the wrong tank.

[@Moradollie]

This video was made 7 years ago. A LOT of science has been done since then. I work as a manager at a float spa. We treat it like a luxury medical spa. Studies show it takes 3-4+ times to start to feel genuine relief. Studies show good relief from PTSD, anxiety, and can potentially help calm adhd. It also helps chronic pain. I went into this job with 8 years experience in healthcare and a biology minor. I never did this specific type of job before. I thoroughly analyzed the science and was frankly surprised to see the good science benefits from it. Our spa DOES NOT turn it into a snake oil salesman. We are straight up with you - if we don't feel your specific circumstances won't benefit, we won't try to sell a float to you.

[@ThrottleKitty]

Sensory Deprivation Tanks are basically a short cut to meditating. You can do the same thing in your home for free with enough focus and clearing your mind. If you find it really hard to focus, visiting one of these tanks is a good way to get a taste for it!

[@fasteddiesgarage101]

Sensory deprivation tanks are awesome for meditating in.

[@MrGreFunky]

Not all changes come in psychical form, deprivation tanks are more about physiological improvement, the ability to think clearly and actually relax in a way never experienced before can be quite eye opening.

[@tooljack4439]

Flotation really works. I've done it 10 times. There are clinical trials going on right now that will show how the effects could be used to treat anxiety.

[@chickadeestevenson5440]

As someone with ASD and migraines, I'd love to OWN a sensory Dep tank, for calming me down if I hit a meltdown.

[@npc6817]

May I suggest a warm bath in the dark and some good ear plugs?

[@sellbythebell]

The float tank is totally worth at least trying once. It's very relaxing and cool feeling.

[@npiper]

You8 forgot to bring up the other part of the flotation tank experiments, the participants were often high as balls, something else linked to pain releife relaxation and increased creativity (not just anecdotally). Drugs of choice were generally barbiturates and various psychoactive compounds.

[@jackielinde7568]

"The patients were... what? What were the patients? Medicated? No, no, no... too weak. Stoned? Nope... Trippy? Uhg... no! What were the patients? Oh! They were 'high as balls'! That'll work" +Echo_Hotel probably

[@npiper]

Jack Linde no patients, just test subjects usually the experiment designer among them. High, tripping, wasted, call it whatever, the progressive intellectual class was big into altered states by 1970 and they scared the hell out of Richard Nixon, so the War on Drugs. He probably did himself and his causes a big disservice with that but who really knows.

I was thinking they sounded absolutely horrible and torturous (adhd / extrovert-leaning ambivert / inner ear chronic problems and damage, etc. etc. etc.) *UNTIL* I just saw your comment. ABSOLUTELY. I am the exact opposite of the above when I have migraines, and I am totally convinced that going into one of those when a migraine is happening would be the most absolutely M-Fing gift from God that you never even imagined would possibly exist!!!! 🤕😓

Please, from one brother to a family member, try this most wonderful way to be close to GOD.

[@JasonCaldwellBufferkiller]

This is the first time I've heard anyone talk about benefits of a sensory deprivation tank. I thought people were paying for the experience, not health benefits.

[@YourFaceisPretty]

Yeah, most of the industry is on board for the latter. There are tests being done on the benefits, if they can be substantiated. But most people are there to chill with their brains, or get away from the world.

[@JasonCaldwellBufferkiller]

That's why I did it. I never thought there were going to be any physical benefits at all. I just assumed it was going to allow me time to relax with my thoughts, and that's what it did. Some of my friends freaked out in them.

[@jasonclough8892]

Wait so you've done this rant and haven't tried it? Lol I mean what was YOUR experience of it?

[@CmdrFirewalker]

I first heard of sensory deprevation tanks when I was a teen ... on the pilot episode of Hawaii Five-O (The Jack Lord one). It was used for torture ... great episode :)

When it comes to floating in warm, dense water to relax i'll just take a couple of weeks and go snorkeling in the Maldives thanks :-)

[@vinnyaustin195]

I'm absolutely skeptical about new agey pseudo remedies, but I've tried the float tank. I have a stressful job with kids, so 90 minutes of pure stillness and quiet is worth $60 in and of itself. Second, my back felt GREAT afterwards, and my skin was smooth and looked healthier for about a week. No hallucinations, just a lot of relaxation, which is worth it to me.

[@maltava4534]

These are all kinda interesting experiences though. I did the sensory deprivation thing because some people experience hallucinations. Overall it was very relaxing but not what I expected. The salts they used to achieve neutral buoyancy though did wonders for my skin, so soft, so smooth. Would recommend at least once.

[@DrewColpurs]

I'd consider a sensory deprivation tank just for the experience.

[@MatthewBishop64]

Great to see SciShow letting people know what science ISN'T.

[@Kalleosini]

Sensory deprivation tanks are used as medicine? I only knew of them as recreational

[@mark.mazzarella]

I'm pretty sure most people use them recreationally, or because some artists say it helps boost creativity

[@KittyBoom360]

well, even then, recreational stuff is often better than medicine, else we just call it recreational medicine. how well it works depends on how well you can recreate.

[@MarkShaneHansen]

That's because in the more civilized parts of the world, they're not allowed to be marketed as medicinal, since these areas are governed by laws protecting citizens from false advertising. Marketing them as recreational is naturally less restricted. On a sidenote, nowadays I've found them to mostly be referred to as isolation tanks. I wonder if that's just me or SciShow had other reasons for referring to them as sensory deprivation tanks.

[@rcnacura]

I love the floating tanks, I use it as a way to escape the constant craziness of San Francisco. Also one of the few places I can go without hearing anything but my own breathing and actually sleep in water without drowning. Try going to sleep when you constantly here people drunk talking/shouting, fire trucks or police sirens, loud busses or cars constantly wizzing by your door/window. But for those that get psychedelic effects, this has never happened to me. Its just like closing your eyes in the night.

[@pyrusmasterdan1]

For my birthday I got to spend one hour in a deprivation tank, and damn it was nice! If you like meditation and stuff, then it's totally worth to try it out. It felt like I had a good night worth of sleep and felt rejuvenated for at least a few days. I don't have experience with the whole body cryo-therapy, but it certainly helps to apply ice on sore muscles after a hard workout, so I think that certainly helps athletes with recovery.

"except you are inherited it,and are bored,I might do it" exactly my thought

[@antti-jussikemppainen305]

For people suffering from rheumatism and are under constant medication to cope with the pains, the cold chambers or saunas offer proven ways to ease pain without painkillers. Thus helping the patient in many ways. Keeping the levels of medication lower and thus enabling longer use of current medicine and naturally keeping the side-effects of the medicines a bit lower. And of course helping with the pains. The more common way to help with the pains is to go ice swimming. Preferably daily. I couldn't find any usefull links in English on the matter, only in Finnish as the practice is well known and widely used in Finland.

[@TheSH1N1GAM1]

I wanted to go into a sensory deprivation tank just because it sounds like fun.

I finally tried a float tank this week. The floating part was awesome, since I'm a sinker and can't float to save my life. But the dark wasn't anything special. I did however get to see the fractal geometry in the back of my eyes animate for about 2-3 minutes before the animation of faint lines gave way to a more of a plasma radial effect that seemed to be in synch with my heart beat. Other than that, I don't think it was worth the $60, to do again. Do it once for the experience, sure. But I'd be more inclined to invest in the Zen Float tank for home, than I would to keep spending that kind of money to get something from it. I dunno... I live a very chill lifestyle, low stress as it is. So, the hour break wasn't anything that I felt I "needed" to recharge with. I'm glad I did it, to say I did it. But I get the sneaking suspicion that regular floaters only do it so they can brag to their friends about it.

[@Gbelk]

As an athlete I use Ice Baths for recovery sometimes when I do a lot of running, sprinting or leg work in general, but never much below 55-60 degrees Fahrenheit... I can't imagine standing in -100 degrees Celsius does much more than that and seems a lot more risky...

[@tallatech]

Plus I'd imagine a longer time in a less cold area would be more effective.

[@Izandaia]

I might do the sensory deprivation one for a lark. Probably not a whole hour though if there's shorter options.

The sensory deprivation tank was awesome just because you can veg out and feel like you're floating. It was trippy, I had to keep touching the sides and stuff to remind myself where I was. But it was super relaxing nonetheless, which was the only reason I did it. XD

If Fringe has taught me anything, is that sensory deprivation tanks can be used to transport you to another universe.

it's $45 for a float at my place - my 3rd year in biz and it's a good tool for sure. other studies about magnesium sulfate (Epsom salt) should be considered. there's. also good studies about theta brain waves. So if you get time and chance to float try it :)
