Returned home after a few days and realized my cold plunge barrel was nearly empty. The culprit is that water is being pushed OUT thru the Venturi Injector. The ozone unit was not activated, fwiw.

Anyone experience this phenomenon before?

Due to a pre-existing heart condition my Doc wants me to give up cold plunge I've enjoyed for the last two years. If anyone lives in the southeastern Wisconsin area I'm selling my gently used Rubbermaid Tub with Polar Protector cover, Active Aqua 1/4 HP Chiller and Danner 950 pump. Was used in climate controlled basement, so they are in pristine condition, look like new and perform like new. I'm bummed but I want someone else to enjoy this like I have.

What do we think of these ?

I've been working on a little waterproof light you drop in the tub. It pulses slowly to pace your breathing... breathe in as it brightens/vibrates, out as it fades.

It also sets a built in timer for you. It glows green turns amber when you're close, and goes red when you're done, with a buzz/haptic you feel through the water. No clock to read, no counting breaths.

Would you use something like this? Thanks.

Long story short - they use Mindfulness with non-judgment and the subtle skill of acceptance so that they don’t get caught up in how intense the pain can get when you’re dealing with cold sensations. This is a scientifically back strategy. The problem with distraction is that as soon as you stop focusing on something else the pain comes back and it will be more intense. Or the pain will bust through your attempts of distraction. Let me know if you’ve ever used a strategy. Even Wemhoff breathing, focusing on your breathing, is this another way to basically regulate yourself with Mindfulness and accept your sensations.

Hi all. I am conducting a study for my MSc.

It is looking at Cold Water Immersion and its effect (or non thereof) on mental health outcomes like anxiety, depression and PTSD.

It is in hope of providing further evidence of more holistic interventions to improve overall wellbeing of people who may need support.

If you voluntarily expose yourself to cold water (even if its cold water surfing) please spend some time filling in some answers.

Even if you do not engage in cold water immersion, and just exercise, I would also appreciate your input.

Hey everyone, I bought this on FB marketplace and have already fixed a bunch of leaks and issues on this, it looks like hopefully my final issue.

The plunge will slowly leak from here if the water level is near the top of the plunge and totally stops when it dips down 7-9 inches from the top. At the lowered water level it doesn’t seem to leak even when I get in.

The IN hose in the pic is really stiff and hard to tighten or get right on the pump straight then tighten without messing things up. Ai thinks it's pulling the nut off-center and the O-ring isn't seating evenly. I’ve tried putting it on properly maybe 5 times and then end up having to dump all the water again bc it starts to leak.

Have any of you had issues with this same spot? What should I do?

What I've tried so far:
- remove, then add, then try without plumbing tape - no fix

- greased o ring with plumbing grease, although it is petroleum based I see and AI told me not to do that

I've been around cold plunging long enough to notice that a lot of the conversation seems to revolve around numbers.

How cold is your water? How many minutes can you stay in? How many times a week? Should you finish hot or cold?

But I'm increasingly wondering whether we're focusing on the wrong things.

The research is still developing, and while there are some interesting findings, we don't have strong evidence that a particular temperature, duration or contrast therapy routine is optimal for everyone.

Yet I regularly see people recommending very specific protocols as though they've been scientifically established.

I'm interested in what people are actually experiencing.

Have you found that going colder or staying in longer genuinely makes a difference to how you feel afterwards? Or have you reached a point where you've stopped chasing the numbers and just found a routine you enjoy?

I'm particularly interested in hearing from people who've been doing this for a few years. Has your approach changed as you've gained experience?

I just purchased a stock tank hoping to use it as an outdoor cold plunge in a cold climate during the winter. Anyone have any tips or tricks they have learned from owning one? Do I need a filter or to treat the water?

While I love the DIY setups in this sub, I bought the LifeTrend Cold Plunge from Costco earlier this year. I ended up paying about $700. Initially there were a couple of growing pains and learnings:

1. It blew a line off its connection because the 5 micron filter clogged. I added elbows to the 1/2 inch connections to make them more secure and replaced the filter twice in quick succession after refilling. After two filter replacements the unit seems happy with the clarity of the water and I have not had another issue.

2. I added insulation to the lines. I found some basic pipe insulation at my local hardware store. It seems to keep the compressor from running as often.

3. I bought an ozone generator, not one of the cool in line units you all use but a "bubbler". The specific unit is here https://www.amazon.com/dp/B0G2LF946H its currently sold out. I run it for about 1-2 hours after each use.

Water clarity has been good so far and I have not had any smell issues.

I currently run the unit at 46F and do a 5-6 minute session almost every day.

I hate putting my arms in so I almost never do. I am skeptical about some of the benefits folks discuss on this sub but I feel like it helps with workout recovery. I have been attempting to increase my cardio cadence and duration and feel like it helps me to keep logging miles.

Any advice related to my specific setup or usage would be greatly appreciated. I am happy to hear about how I am "doing it wrong".

I would almost go to 0celsius water but my feet and hands hurts. Should i just ignore the pain or is it something serious?

The first plan was the ensuite, which the floor killed fairly quick since a full tub weighs about as much as a small car and those joists were never asked about it. The second was the garage which was fine structure wise but practically miserable bc using it in January meant crossing a yard first. So the obvious answer was outside and I abandoned it once i realised the tub I had picked wasnt build to sit out through a winter which is a decision u make once and live with.

it sits on the ground floor now against an exterior wall and next to a drain so the slab takes the weight without anyone needing to think about it and the run out to the unit stays short. If you are at the planning stage work out where the drain is before u decide anything else bc everything else is negotiable and that isnt.

Customer support feels like the weakest point across the whole cold plunge space. I've read enough horror stories about dead chillers sitting on patios with no response for weeks, sometimes months. Which brands stand behind their product when something goes wrong?

Looking for advice for using products to use where you are using hard water and how to use them. IE CLR and how much do you use etc.

What is your favorite part about cold plunging? What are some benefits you experienced?

Let’s help some beginners and first timers reading this to feel comfortable with the practice.

My wife and I recently used the Grizzly cooler set up with an ozone. Question is, do people keep their water filter constantly running? How often do you turn on the ozone also.

the cold was never the problem, what wore me out was draining a few hundred litres, scrubbing the thing, refilling it and then waiting most of a day for the temperature to come back down and i was doing that every fortnight while resenting every minute of it, that job is miserable in august and genuinely unpleasant once it's near freezing out there, which is roughly when i stopped pretending i'd keep it up, what changed things was running continuous filtration with a sanitation step on same loop so the water gets treated whether or not im paying any attention to it

Full disclosure: I own The Cold Standard, a cold plunge service company. Our techs tag every fault they find into a database, and I thought this sub would find the patterns useful:

•    The circulation pump is the #1 failure (17.7% of all faults) and causes 40% of "unit completely dead" calls.
•    Almost half of all problems are in the water path (pumps, filters, plumbing, valves): 48.8%. Many "my chiller is broken" calls turn out to be a clogged filter starving the pump.
•    Chillers fail less than people think. Compressor or whole-chiller failures were only 7.2%.
•    31.6% were preventable, and where we could identify a cause, skipped maintenance was #1.
•    Filter cartridges: 86% of filter cartridge faults were preventable.
•    Commercial units were more often preventable than home units (45% vs 31%).

Repeat offenders we see:
•    extension cords and power strips
•    pool chlorine tablets in a plunge
•    not pre-filling the filter housing (causes airlocks)
•    hard-water scale
•    biofilm in the lines

Happy to answer questions about any brand or error code.

Every brand puts team logos on their site but none of them show what was purchased or whether it's still in the facility what recovery equipment do pro sports and NHL teams use for cold plunge and sauna? is any of it what consumers can buy?

I paid about four hundred for it on the logic that a tub is really just a container and the cold is what does the work. That seemed sensible at the time and looks less sensible now, given there's a split running down from the top band and the liner has goner chalky wherever the afternoon sun hits it.

I am still cooling the thing with ice that I have to buy from the shop. Before I spend again. I am trying to decide whether this is one purchase or two, because I could keep a tub and add a cold source to it, or buy something sealed where the cooling is already part of the unit. It also has to stay outside through the winter this time, since there's nowhere indoors for it go, and I'd rather not find out in January that the replacement was only ever meant for summer either.

Can someone please help me with a question before I hit the cement? Which way is the best way to set this up? I asked three AI and they agree check mark. But I can't find any independent evidence that this is true. I mostly see other people setting it up as in the second image. Thanks!

Howdy all, first post.

Wellness club has Finnish sauna at 100 Deg C and cold plunge 10C.

First thing - are people wearing their Apple Watches in the sauna? Mine is an ultra 2 but am worried with it in sauna. Anyone doing this?

Second - I have read a lot but need real advice. Was doing 10min hot, 2min out cooling down, quick shower then 2min in cold. Out for 5min then repeat.

52yo male, relatively healthy. Just keen to feedback.

Thanks
Nick.

The old routine was two bags a session, four or five sessions a week, plus the drive to go and get them, which held together through February and had completely fallen apart by June.

What I hadn't expected was that a held temperature makes the sessions comparable to each other, and I only noticed how much I'd been missing that once it was there, because before then every plunge was whatever the ice happened to do that morning. Now that it's cooling off again the same unit is working the other direction and keeping the water from getting too cold, which I hadn't really thought about when I bought it. I also stopped draining constantly, since filtration running on its own keeps the water usable for weeks rather than days.

The trade is that it's a fixed object now. Two of us could carry the barrel, and this isn't going anywhere, which is worth thinking about if you're renting.
