An ozone sauna is a type of sauna which combines ozone gas with sweating. The sauna itself has to allow for the head of the person to remain outside in order to prevent breathing ozone in. Steam comes in from one side and ozone gas from the other side. Infrared saunas can also be used for ozone purposes. Unfortunately, only few infrared saunas are resistant to ozone. It’s possible to turn most portable sauna tents into ozone saunas.
Here is what you need in order to set up an ozone sauna.
1. Oxygen source (tank or concentrator) including low flow regulator
2. Ozone generator
3. Extra silicone tubing
4. Sauna tent with a steamer pot, or an infrared sauna tent
5. Mask and a fan
6. Extras: Several towels, a chair
1. Oxygen source:
Either an oxygen tank or an oxygen concentrator can be used which produces oxygen of at least 90% purity. Ozone saunas require a relatively high flow of oxygen of around 0.5 LPM (= 1/2 LPM). The heat inside the sauna continuously destroys a lot of ozone, so a higher volume of gas is required to make up for the constant destruction. Because of the relatively high flow, more oxygen is used up than with other ozone applications. For ozone saunas, oxygen concentrators offer an advantage over oxygen tanks because they cannot run out of oxygen. Some high flow (0 to 5 LPM) oxygen concentrators can be set to as low as 0.5 LPM, in which case you won’t need an external low flow regulator. Others turn themselves off at flows below 1 LPM, so you will need an additional low flow regulator. Same if you use an oxygen tank.
2. Ozone generator:
It should be an oxygen fed generator which can produce ozone concentrations of at least 15 mcg/ml at a flow of 1/2 LPM. Any of the recommended generators on this page will do the job. The one in the pictures above is the EliteO3 Dual Cell from Promolife.
3. Silicone tubing:
This is how the ozone is transported from the ozone generator into the sauna and what turns a regular sauna into an ozone sauna. Use a fairly long piece of tubing of around 5 feet. Just drop it through the neck hole of the sauna tent.
4. Sauna tent with a steamer pot:
This type of saunas can be bought on ebay or amazon for sometimes under $100. I prefer to use steam saunas instead of infrared saunas since the infrared models are not always ozone compatible. Most of those foldable tents come with a pot which creates steam by boiling water.
Some foldable saunas already come with a chair. With others you will have to buy one separately.
6. Towels and a chair:
You will need a lot of towels: one around your neck to block the steam and the ozone, at least one for the chair, a few to put inside the sauna, and a few underneath the sauna to protect your floor (or you use a piece of plastic cover). So you will need many more towels than I show in the pictures above. Best is to use either all white or old towels since ozone will bleach them.
Most foldable saunas already come with a chair. But often the chair is not comfortable enough. So be prepared to make a trip to your local Home Depot to pick up a better option or check out amazon.
1. Assemble the sauna according to the instructions that came with it. Remember to place either towels underneath the tent or a plastic sheet to protect your floor. Pour some distilled water into the steamer pot and turn it to the highest setting so that it starts to boil quickly.
2. In the meantime prepare everything else: put some additional towels at the bottom inside the sauna (to collect the water), put the chair inside the sauna, and place the fan in front of the sauna.
3. Connect the oxygen source with the ozone generator, plug both into the power supply, connect the extra long silicone tubing to the ozone output port on the ozone generator. Slip the other end of the silicone tubing through the neck hole of the sauna. Have the mask close by.
4. Once the water starts to boil, turn the oxygen concentrator on, set the flow to 1/2 LPM.
5. Get undressed.
6. Put the mask on.
7. Turn the ozone generator on, set it to an ozone concentration of around 20 mcg/ml. You can also use higher concentrations. Just keep in mind that the higher the concentration, the more severe the rash can be, see below.
8. Turn the fan on.
9. Take a towel and wrap it around your neck. Step into the sauna and close the zipper. While in the sauna make sure you are not sitting on the hose, otherwise the ozone outflow will be blocked. You can hold the hose against any part of your body you want like the liver, your lungs or your back.
10. Remain in the sauna for ideally 30 min.
11. When done, unzip the sauna, step out, turn off the fan, then the ozone generator, the oxygen concentrator, and the steamer pot. Take the mask off and dry yourself with the towel. Or take a shower.
12. Remember to collect the water at the bottom of the sauna tent and to dry it out properly, otherwise it will start to mold.
1. What kind of sauna can be used as an ozone sauna?
Any sauna which satisfies the following four criteria can be used as an ozone sauna:
A) Your head remains outside of the sauna (to be able to breathe air instead of ozone. Breathing ozone should be avoided as much as possible during ozone treatments.)
B) It generates enough heat to make you sweat. (Theoretically, both steam and infrared saunas can be used but there are only few infrared saunas which are made entirely of ozone compatible materials. Most cheap, foldable infrared saunas can contain non-ozone resistant wire linings and heaters which can get destroyed by ozone and in rare instances cause fires.)
C) It offers an opening through which you can introduce the ozone output hose. Usually, the ozone output is slipped into the sauna through the neck hole. Some saunas have extra zippers for hands which can also be used.
D) It is made of ozone compatible material. Hard shell saunas made from fiberglass or acrylic offer the ideal solution. Foldable cloth saunas have proven to be surprisingly ozone resistant and offer a great and affordable alternative.
Full body walk-in-saunas should not be used for ozone therapy because they do not allow to leave the head outside of the steam/ozone mixture, hence they make it impossible not to breathe in ozone, something which should be avoided during ozone treatments.
2. Are foldable saunas toxic?
Many people worry that the foldable sauna tents might emit toxic chemicals which could then be absorbed through the skin.
Most portable saunas are made of PVC or vinyl cloth. PVC is a very ozone resistant material. The problem is that some types of PVC use plastic softeners which can be hazardous to human health. Fact is that many of the simple sauna tents emit a strong chemical scent when new. An effective way to get rid of the smell is to run ozone through it. After 30 min the scent is in most cases gone. So it’s possible that the ozone prevents any further release of chemicals.
There are many people (me included) who have used the simple foldable saunas for ozone purposes for years. Even after hundreds of ozone applications, the saunas remain intact without any holes or other visible damage to the material.
3. What do you think of hard-shell saunas?
I think they are the ultimate and best solution when it comes to ozone saunas. They are made out of highly ozone resistant materials (glass fiber or acrylic) and are more spacious than the tent saunas. Overall, they offer a much better ozone experience.
The drawback is the price which can run up to several thousand dollars. And: they can’t be disassembled, so they require more space.
4. Have you heard of HOCATT saunas?
Yes, the HOCATT is a type of ozone sauna. It also adds carbonic acid which is supposed to enhance the ozone experience by improving blood circulation.
The HOCATT is the crème de la crème of ozone saunas. There is at least one account of a woman having seen great improvement in her MS symptoms after regular HOCATT treatments.
5. I’m heat intolerant. What can I do instead?
If you’re heat intolerant, I suggest to do either shorter sauna sessions of 10 minutes and see if you can work it up over time.
Another solution is the body suit. There is no heat involved, apart from what your own body produces.
6. Where can I buy a foldable ozone sauna?
There are no ready-to-buy foldable ozone saunas. You need to build them by combining a separately bought foldable sauna tent with the ozone equipment. I explain it in this video.
7. Are ozone saunas useless? Doesn’t the heat destroy all the ozone?
Here is my answer:
Risk: extremely itchy, sometimes oozing rash, mostly over the abdomen and back. Usually looks like small red dots, but can also look like slightly bigger red round circles or streaks.
- once the rash sets in reduce frequency, ozone concentration and/or length of time of the saunas, but do not stop entirely
- apply a stream of hot and cold water to the itching skin for a few minutes each
- apply any of the following:
- Previous stroke (this is for saunas in general, not exclusively ozone saunas)
- Pregnancy (this is for saunas in general, not exclusively ozone saunas)
- Transplanted organ (ozone is known to stimulate the immune system which could lead to a rejection of the foreign organ)
- Hyperthyroidism (light forms of hyperthyroidism are not a contraindication; more severe, untreated cases could be problematic. Ozone is known to stimulate hormone production, but also to be a hormone modulator.)
- High blood pressure
